Explanation:
rectangular plate is supported by three cables as shown. knowing that the tension in cable ac is 60 n, determine the weight of the plate.
The weight of the plate is equal to -(60 × LAC)/LAB - 60.
What is plate?Plate is a flat dish used for serving food. It is usually made of ceramic, glass, metal, or plastic, and is sometimes decorated with patterns or designs. Plates are usually round, but can also be rectangular, square, or oval. They are used for a variety of meals, from casual to formal.
Using the principle of static equilibrium, we can set up a system of equations to solve for the weight of the plate.
Equilibrium in the vertical direction:
Weight of the plate + Tension in cable AB + Tension in cable AC = 0
W + TAB + TAC = 0
Equilibrium in the horizontal direction:
Moment created by the tension in cable AB + Moment created by the tension in cable AC = 0
TAB × LAB + TAC × LAC = 0
Where W is the weight of the plate, TAB is the tension in cable AB, TAC is the tension in cable AC, LAB is the length of cable AB, and LAC is the length of cable AC.
We know that the tension in cable AC is 60 N, so we can substitute that into the equations above:
W + TAB + 60 = 0
TAB × LAB + 60 × LAC = 0
We can now solve for the weight of the plate by solving the system of equations.
Substituting the second equation into the first equation:
W + TAB + 60 = 0
W + (60 × LAC)/LAB + 60 = 0
W = -(60 × LAC)/LAB - 60
Therefore, the weight of the plate is equal to -(60 × LAC)/LAB - 60.

Rocket observations show that dust particles in Earth's upper atmosphere are often electrically charged.a) Find the distance separating two dust particles if each has a charge of +e and the Coulomb force between them has magnitude 1.00x10−14−14N.b) Calculate the mass of one of the dust particles if this Coulomb force would accelerate it at 4.50x1088m/s22. (In the upper atmosphere, effects from other nearby charges typically result in a small net force and acceleration.)
a. The distance separating two dust particles if each has a charge of +e and the Coulomb force is 2.5 × 10⁻³ m
b. The mass of one of the dust particles if this Coulomb force would accelerate it is 2.22 x 10⁻²³ kg.
What is force?
Force is a physical quantity that represents the interaction between two objects that cause changes in motion of the objects. Force can be defined as the push or pull effect on an object. It is a vector quantity, which means it has both magnitude and direction. The unit of force in the International System of Units (SI) is the Newton (N), which is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared.
a) The force between two charged particles can be calculated using Coulomb's law, which states that the force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them:
F = k × q1 × q2 / r²
where k is the Coulomb constant (8.99 x 10⁹ N m²/C²), q1 and q2 are the charges of the two particles, and r is the distance between them.
Given that the force between the two particles is 1.00 x 10⁻¹⁴ N and each particle has a charge of +e, we can rearrange the equation to solve for r:
r = [tex]$ \sqrt{\frac{k \times q_1 \times q_2 }{ F} }[/tex]
= [tex]$ \mathrm{ \sqrt{\frac{8.99 \times 10^2 N m^2/C^2 \times 2e^2 }{ 1.00 \times 10^{-14} N} } }[/tex]
= 2.5 × 10⁻³ m
b) To calculate the mass of one of the dust particles, we can use Newton's second law, which states that the net force acting on an object is equal to its mass times its acceleration:
F = m × a
where F is the force, m is the mass, and a is the acceleration. Given that the acceleration of the particle is 4.50 x 10⁸ m/s², we can rearrange the equation to solve for m:
m = F / a
[tex]$ \mathrm{= \frac{1.00 \times 10^{-14} N}{ 4.50 \times 10^8 m/s^2} }[/tex]

(h) The magnitude of the net electric force on particle C is 1.01 x 10⁻⁷ N.
Net Electric ForceThe electric force exerted by a particle on another particle can be calculated using Coulomb's Law, which states that the force between two point charges is given by:
F = k * q1 * q2 / r²
where k is the Coulomb constant (8.99 x 10⁹ Nm²/C²), q1 and q2 are the magnitudes of the charges, and r is the distance between the two particles.
(a) The x component of the electric force exerted by particle A on C can be found by considering the x direction only. The distance between A and C can be found using the Pythagorean theorem:
r = sqrt((4.00 m)² + (3.00 m)²) = 5.00 m
The electric force in the x direction can then be found as follows:
F_x = k * q1 * q3 / r² * cos(θ)
where q1 is the charge of particle A (3.24 x 10⁻⁴ C), q3 is the charge of particle C (1.01 x 10⁻⁴ C), and θ is the angle between the line connecting the two particles and the x-axis. Since the line is in the first quadrant, cos(θ) is positive:
θ = arctan(3.00 m / 4.00 m) = 0.93 radians
cos(θ) = cos(0.93) = 0.80
F_x = k * q1 * q3 / r² * cos(θ) = (8.99 x 10⁹ Nm²/C²) * (3.24 x 10⁻⁴ C) * (1.01 x 10⁻⁴ C) / (5.00 m)² * 0.80 = 2.29 x 10⁻⁷ N
(b) The y component of the force exerted by A on C can be found in a similar manner:
F_y = k * q1 * q3 / r² * sin(θ)
sin(θ) = sin(0.93) = 0.60
F_y = k * q1 * q3 / r² * sin(θ) = (8.99 x 10⁹ Nm²/C²) * (3.24 x 10⁻⁴ C) * (1.01 x 10⁻⁴ C) / (5.00 m)² * 0.60 = 1.72 x 10⁻⁷ N
(c) The magnitude of the force exerted by B on C can be found using Coulomb's Law:
F = k * q2 * q3 / r²
where q2 is the charge of particle B (-5.64 x 10⁻⁴ C) and r is the distance between the two particles:
r = sqrt((4.00 m)² + (3.00 m)²) = 5.00 m
F = k * q2 * q3 / r² = (8.99 x 10⁹ Nm²/C²) * (-5.64 x 10⁻⁴ C) * (1.01 x 10⁻⁴ C) / (5.00 m)²= -3.96 x 10⁻⁷ N
(d) The x component of the force exerted by B on C can be found by considering the x direction only:
F_x = k * q2 * q3 / r² * cos(θ)
where q2 is the charge of particle B (-5.64 x 10⁻⁴ C), q3 is the charge of particle C (1.01 x 10⁻⁴ C), and θ is the angle between the line connecting the two particles and the x-axis. Since the line is in the first quadrant, cos(θ) is positive:
θ = arctan(3.00 m / 4.00 m) = 0.93 radians
cos(θ) = cos(0.93) = 0.80
F_x = k * q2 * q3 / r² * cos(θ) = (8.99 x 10⁹ Nm²/C²) * (-5.64 x 10⁻⁴ C) * (1.01 x 10⁻⁴C) / (5.00 m)² * 0.80 = -3.17 x 10⁻⁷ N
(e) The y component of the force exerted by B on C can be found in a similar manner:
F_y = k * q2 * q3 / r² * sin(θ)
sin(θ) = sin(0.93) = 0.60
F_y = k * q2 * q3 / r² * sin(θ) = (8.99 x 10⁹ Nm²/C²) * (-5.64 x 10⁻⁴ C) * (1.01 x 10⁻⁴ C) / (5.00 m)² * 0.60 = -2.38 x 10⁻⁷ N
(f) The x component of the resultant force can be found by summing the x components from parts (a) and (d):
F_x_resultant = F_x(A on C) + F_x(B on C) = 2.29 x 10⁻⁷ N + (-3.17 x 10⁻⁷ N) = -0.88 x 10⁻⁷ N
(g) The y component of the resultant force can be found by summing the y components from parts (b) and (e):
F_y_resultant = F_y(A on C) + F_y(B on C) = 1.72 x 10⁻⁷ N + (-2.38 x 10⁻⁷ N) = -0.66 x 10⁻⁷ N
(h) The magnitude of the resultant force can be found using the Pythagorean theorem:
F_resultant = sqrt(F_x_resultant² + F_y_resultant²) = sqrt((-0.88 x 10⁻⁷ N)² + (-0.66 x 10⁻⁷ N)²) = 1.01 x 10⁻⁷ N

A 11-kg cannonball is fired with a velocity of 19m / s from 28 m above the ground . It hits a target that is 11 m above the ground . With what velocity does it hit, in m / s ? (Round your answer to one decimal place if necessary .)
The required cannonball hits the target with a velocity of 26.25 m/s.
What is the law of conservation of energy?The law of conservation of energy states that sum, when the object is in motion the sum of the initial energy, is equal to the sum of the final energy.
The velocity of the cannonball just before it hits the target can be determined using the law of conservation of energy, which states that the total energy of a system is constant.
The initial potential energy of the cannonball is given by:
PE(i) = mgh
PE(i) = 11 kg * 9.8 m/s^2 * 28 m
PE(i) = 3018.4 J
The final potential energy of the cannonball is given by:
PE(f) = mgh
PE(f) = 11 kg * 9.8 m/s^2 * 11 m
PE(f) = 1185.8J
The initial kinetic energy of the cannonball is given by:
KE(i) = 0.5 * m * v^2
KE(i) = 0.5 * 11 kg * 19 m/s^2
KE(i) = 1985.5 J
Since the total energy of the system is conserved, we have:
PE(i)l + KE(i) = PE_(f) + KE_(f)
3018.4 J + 1985.5 J = 1185.8 J + KE(f)
KE(f) = 3791.1 J
Finally, the velocity of the cannonball just before it hits the target can be calculated from its kinetic energy:
v^2 = 2 * KE / m
v^2 = 2 * 3791.1J / 11 kg
v = √(2 * 3791.1 J / 11 kg)
v = 26.25 m/s
So the cannonball hits the target with a velocity of 26.25 m/s.

determine the direction of the resultant force, measured counterclockwise from the positive x axis. express your answer using three significant figures.
Resultant force direction = 11.08 degrees counter-clockwise from the positive x-axis.
In order to address this issue, we must first divide these forces into their corresponding x and y components, which we must then combine to determine the final force.
Given the magnitude of force (F1) = 32kN
The angle of direction (θ1) = 30°
F1x = -32k x cos(30°) = -27.7kN
F1y = -32 x sin(30°) = -16kN
Given a triangle, let cos(θ) = 5/13 = 0.99 then θ = 67.3°
The magnitude of force F2 = 26kN
The angle of direction (θ2) = 0.99°
F2x = -26 x cos(67.3°) = 10.03kN
F2y = 26 x sin(67.3°) = 23.9kN
Frx = F1x + F2x = -37.73kN
Fry = F1y + F2y = 7.9kN
Let the resultant force = Fr then,
Fr^2 = Frx^2 + Fry^2
Fr^2 = (-37.73)^2 + (7.9)^2
Fr = √1423.55+62.41 = √1485.96 = 38.5kN
Hence the resultant force = 38.5kN

A 5.7 diameter horizontal pipe gradually narrows to 3.6 cm. The the water flows through this pipe at certain rate, the gauge pressure in these two sections is 32.5 kPa and 24.0 kPa, respectively. What is the volume of rate of flow?
The volume rate of flow is approximately 102.3 cm if a 5.7 diameter horizontal pipe gradually narrows to 3.6 cm.
To determine the volume rate of flow in a pipe, we can use the equation for the continuity of fluid flow:
[tex]A1 * v1 = A2 * v2[/tex]
where A1 and A2 are the cross-sectional areas of the two sections of the pipe and v1 and v2 are the velocities of the fluid in each section.
We can first convert the diameter measurements to cross-sectional areas:
[tex]A1 = (π / 4) * (5.7 cm)^2 = 40.2 cm^2A2 = (π / 4) * (3.6 cm)^2 = 10.1 cm^2[/tex]
Next, we can use the formula for the velocity of a fluid in a pipe:
[tex]v = (2 * ΔP / ρ)^0.5[/tex]
where ΔP is the pressure difference across the pipe, and ρ is the density of the fluid.
Using this formula, we can find the velocities in each section of the pipe:
[tex]v1 = (2 * (32.5 kPa - 0) / 1000 kg/m^3)^0.5 = 2.53 m/sv2 = (2 * (24.0 kPa - 0) / 1000 kg/m^3)^0.5 = 1.94 m/s[/tex]
Finally, using the continuity equation, we can find the volume rate of flow:
[tex]V = A1 * v1 = A2 * v2V = 40.2 cm^2 * 2.53 m/s = 10.1 cm^2 * 1.94 m/sV = 102.3 cm^3/s[/tex]

a = W / m
Where m is the mass of the person, which can be calculated using the acceleration due to gravity:
m = W / g = 414.2 N / 9.8 m/s^2 = 42.3 kg
Substituting the mass into the equation for acceleration:
a = 414.2 N / 42.3 kg = 9.8 m/s^2

ax = dvx/dt = 32.0 - 6.00[tex]t^2 m/s^2[/tex].
The particle achieves its maximum displacement in the positive x-direction when its velocity is zero, which occurs when vx = 0. Solving for t in the equation vx = 32.0t - 2.00[tex]t^3[/tex] = 0, we find that t = ±√(16/3) s. The particle achieves its maximum displacement in the positive x-direction, so we want the positive value of t, which is t = √(16/3) s. Plugging this value of t into the expression for ax, we find that the acceleration of the particle is ax = 32.0 - 6.00(16/3) = -6.00 [tex]m/s^2[/tex].

The ranking of the gravitational force acting on the asteroid are asteroid: sun, asteroid: earth, asteroid: moon, asteroid: asteroid, asteroid: hydrogen atom
What is an asteroid explain?
An asteroid is a small, rocky object that orbits the Sun. Asteroids are much smaller than planets, and are composed mostly of rock and minerals. They range in size from less than 1 meter to hundreds of kilometers across. Most asteroids are found in a region of space between the orbits of Mars and Jupiter known as the asteroid belt. On average, about 100 tons of material from asteroids and comets hits Earth's atmosphere each day. Most of this material is small dust-sized particles that burn up in the atmosphere before they reach the ground.
The gravitational force solely depends on the product of the masses because the distance is the same in each of the five scenarios. The mass of the object on the right determines the relative strength of gravitational force because the same asteroid is in each of the five scenarios on the left. Explore what transpires if we inquire about the gravitational force operating on the object on the right in Part B.

while standing at the edge of a building's roof, chad throws an egg upward with an initial speed of 8.00 m/s. the egg subsequently smashes on the ground, 12.0 m beneath the height from which chad threw it. ignore the effects of air resistance.At what speed does the egg pass the point from which it was thrown?v= _____m/sHow much time t does the egg spend in the air? t=___sWhat total distance d does the egg travel? d=___m
The result is obtained by using the equations in uniformly accelerated straight motion.
Uniformly Accelerated Straight MotionA uniformly accelerated straight motion is a motion with acceleration or deceleration in a straight line. The equations apply in vertical dimension are
v₁ = v₀ + gt
v₁² = v₀² + 2gh
h = v₀t + ½ gt²
Where
v₀ = initial velocityv₁ = final velocityg = acceleration due to gravityt = timeh = heightWhile standing at the edge of a building's roof, Chad throws an egg upward.
Initial speed, v₀ = 8.00 m/sIt finally falls 12.0 beneath the height at which Chad threw it. No air resistance.Find
The speed of the egg when passes the point which it was thrown!The time spent by the egg in the air!The total distance the egg travels!See the illustration picture in the attachment!
The distance between the egg when it was thrown and the highest point it could reach is
v₁² = v₀² - 2gh₁
0 = 8² - 2(10)h₁
64 = 20h₁
h₁ = 3.2 m
The egg then moves downward. The speed when it passes the initial point is
v₂² = v₁² + 2gh₁
v₂² = 0 + 2(10)(3.2)
v₂² = 64
v₂ = 8 m/s
The speed is the same with the initial speed.
The time spent by the egg from initial point to the highest point is
v₁ = v₀ - gt₁
0 = 8 - 10t₁
8 = 10t₁
t₁ = 0.8 s
The time spent from the highest point to the ground is
h = v₀t + ½ gt²
(3.2 + 12) = 0 + ½ (10)t₂²
15.2 = 5t₂²
t₂² = 3.04
t₂ = 1.74 s
The total time spent in the air will be
t = t₁ + t₂
t = 0.8 + 1.74
t = 2.54 s
The total distance traveled by the egg is
= 2(3.2) + 12
= 6.4 + 12
= 18.4 m

Find the magnitude of the electric field, in newtons per coulomb, at the location of q a in the figure, given that q b = q c = q d = 4.9 nC , q = - 0.25 nC , and the square is 12 cm on a side
At the location of q a in the figure, given that q b = q c = q d = 4.9 nC , q = - 0.25 nC , and the square is 12 cm on a side. The magnitude of the electric field at the location of qa is 2.16 x [tex]10^{7}[/tex] N/C.
The electric field at a point due to a point charge is given by the formula:
E = k . q / r^2
where,
k = Coulomb's constant (8.99 x 10^9 Nm^2/C^2),
q = the charge producing the field,
r = the distance from the charge.
Let's call the side length of the square L. The charges qb, qc, and qd are located at the corners of the square, and are equidistant from the point where we want to calculate the electric field, so we can calculate the field due to each of them separately and then add them up.
The distance between the charges and the point of interest is L/√2. The electric field due to each charge can be calculated as:
E = k * 4.9 x 10^-9 C / (L/√2)^2 = k * 4.9 x 10^-9 C / (12/√2)^2 = k * 4.9 x 10^-9 C / (12/1.4142)^2
Adding the contributions from the three charges, the total electric field due to qb, qc, and qd is:
E = 3 * k * 4.9 x 10^-9 C / (12/1.4142)^2
Next, we need to calculate the contribution from the charge q. The electric field due to q can be calculated in the same way, but since q is negative, the direction of the field will be opposite to that due to the other charges:
Eq = - k * -0.25 x 10^-9 C / (L/√2)^2 = k * 0.25 x 10^-9 C / (12/√2)^2
Finally, the total electric field at the point is the sum of the contributions from all the charges:
Etotal = E + Eq = 3 * k * 4.9 x 10^-9 C / (12/1.4142)^2 + k * 0.25 x 10^-9 C / (12/√2)^2
So, the magnitude of the electric field at the location of qa is:
Etotal = √(Ex^2 + Ey^2) = √((3 * k * 4.9 x 10^-9 C / (12/1.4142)^2)^2 + (k * 0.25 x 10^-9 C / (12/√2)^2)^2)Etotal = √((3 * 8.99 x 10^9 Nm^2/C^2 * 4.9 x 10^-9 C / (12/1.4142)^2)^2 + (8.99 x 10^9 Nm^2/C^2 * 0.25 x 10^-9 C / (12/√2)^2)^2) = √((3 * 8.99 x 10^9 Nm^2/C^2 * 4.9 x 10^-9 C / (12/1.4142)^2)^2 + (8.99 x 10^9 Nm^2/C^2 * 0.25 x 10^-9 C / (12/√2)^2)^2) = 2.16 x 10^7 N/CSo the magnitude of the electric field at the location of qa is 2.16 x [tex]10^{7}[/tex] N/C.
