Determination of unknown resistance In order to determine the nature of an electric component (D) we set up an electric circuit as follows → The electric component (D) is connected to a DC generator of adjustable voltage * An ammeter (A) is connected to measure the current I that traverse (D) A voltmeter (V) is connected to measure the voltage U across (D) 1- Draw a diagram that represent this electric circuit.​

The force exerted between the charges q1 and q3 is   -5.25 × 10⁻⁶ N and that between q2 and q3 is -2.93   × 10⁻⁶ N. Hence the net force is - 8.18  × 10⁻⁶ N .

According to Coulomb's law of force, the electrostatic force between two charges separated by a distance of r is given as follows:

Fc = Ke q1 q2 /r²

where Ke = 8.9 × 10⁹ Nm²/C²

Given the charge of  q1 = 3.97  × 10⁻⁹ C

charge of q3  = -5.95 × 10⁻⁹ C

distance r = 0.200 m

then Fc =  8.9 × 10⁹ Nm²/C²  ( 3.97  × 10⁻⁹ C) (-5.95 × 10⁻⁹ C)/(0.200 m)² = -5.25 × 10⁻⁶ N

Similarly, the force on q3  by the charge q2 is calculated as follows:

distance to q2 = 0.30 m

charge of q2 = 4.99 × 10⁻⁹ C.

Then Fc =   8.9 × 10⁹ Nm²/C²  (4.99 × 10⁻⁹ C ) (-5.95× 10⁻⁹ C)/(0.30 m)² = - -2.93 × 10⁻⁶ N

The net electric force acting on A =  3.9 × 10⁻⁵ N - (-1.9 × 10⁻⁵ N) = 5.8 × 10⁻⁵ N.

Therefore, the net electric force acting on q3 is  8.18  × 10⁻⁶ N.

Two point charges are placed on the x-axis as follows: charge  3.97 nC is located at 0.200 m (q1) and charge 4.99 nC (q3) is at -0.304 m .What is the magnitude of the total force exerted by these two charges on a negative point charge q3

= -5.95 nc that is placed at the origin?

Answer:

-11.29 m

Explanation:

The length of the incline can be calculated using the following formula:

L = (Vf^2 - Vi^2) / (2 * a)

where:

L = length of incline

Vf = final speed (15 m/s)

Vi = initial speed (2 m/s)

a = acceleration due to gravity (9.8 m/s^2 on the surface of the Earth)

Since the skier is going downhill, the acceleration is negative.

Substituting the given values into the formula:

L = (15^2 - 2^2) / (2 * -9.8)

L = (225 - 4) / -19.6

L = 221 / -19.6

L = -11.29 m

So the length of the incline is approximately -11.29 meters. This negative value indicates that the skier's final position is lower than the starting position.

The resultant speed of the plane would be 230.03 km/hour

Vectors are the units that have both magnitude and direction. We can directly add and subtract if they are going in the same or the opposite direction. If they are all going in the same direction, we employ the formula that will take the square root of each vector's sum of squares. In this case, the vectors are inclined to one another with angle 45° (plane flying from east to northeastern)

The formula below is used to calculate the resultant vector from two vectors that are inclined to one another. The resultant vector, R, is created when the vectors A and B are inclined at an angle Ø to one another:

                                  R² = A² + B² + 2ABCosØ

Thus, the resultant speed of the plane would be

R² = 200² + 40² + (2 × 200 × 40 × Cos 45°)

R² = 40,000 + 1,600 +11,313.7

Answer: approximately 13.6 m/s.

Explanation: The sled's speed after it has traveled the first 100 m can be determined using the principles of kinematics.  We can use the equations of motion to solve this problem.

First, let's identify the given information:

- Initial speed (v₀) = 9.2 m/s (sled's top speed before starting down the track)

- Distance traveled (s) = 100 m (the first 100 m of the track)

- Angle of the slope (θ) = 9.0° (angle of the track)

To find the sled's speed after traveling 100 m, we need to determine the final speed (v) using the equation of motion that relates initial speed, final speed, distance, and angle:

v² = v₀² + 2as

Here's how we can calculate it step by step:

Convert the angle from degrees to radians:

θ = 9.0° = (9.0° * π) / 180 ≈ 0.157 radians

Determine the acceleration (a) using the gravitational acceleration and the angle of the slope:

a = g * sin(θ)

g ≈ 9.8 m/s² (acceleration due to gravity)

a ≈ 9.8 m/s² * sin(0.157) ≈ 1.36 m/s²

Substitute the known values into the equation of motion:

v² = (9.2 m/s)² + 2 * (1.36 m/s²) * (100 m)

Simplify and solve for v:

v ≈ √(9.2² + 2 * 1.36 * 100) ≈ 13.6 m/s

Therefore, the sled's speed after traveling the first 100 m is approximately 13.6 m/s.

Speed defines the direction in which a body or object is moving. Speed is primarily a scalar quantity. Velocity is basically a vector quantity. Rate of change of distance. Rate of change of displacement.

(a) The rate of change of displacement is known as velocity. It can be calculated by finding the ratio of displacement and total required time. The SI unit for velocity is "m/s", just like velocity.

The work done by the forward force is:

W1 = F1d = 1143 N × 7 m = 8001 J The work done by the second force is:

W2 = F2d = 909 N x 7 m = 6363 J The net work done on the car is the sum of the following he two works.

[tex]\mathrm{W_{net}}[/tex] = W1 + W2 = 8001 J + 6363 J = 14364 J According to the work energy principle, the net work done in a car is equal to the change in its kinetic energy.

[tex]\mathrm{W_{net}}[/tex] = ΔK where ΔK is the change in kinetic energy. Since the car starts from a standing start, the initial kinetic energy is 0, so ΔK equals the final kinetic energy. So it looks like this:

[tex]\mathrm{W_{net}}[/tex] = 14364 J Finally, we can convert this energy to Joules using the following formula:

1 J = 1 kg m²/s²

So it looks like this:

K = 14364 J = (2.2 × 10³ kg) × v² where v is the final velocity of the car. Solving for v gives:

v = √(K / (2.2 × 10³ kg))

= √(14364 J / (2.2 × 10³ kg))

= 4.67 m/s

So when the car reaches 7 m it has a kinetic energy of 14364 J and a terminal velocity of 4.67 m/s.

Velocity is described as the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time.

The momentum of the boy after he pushes off is given by m_boy * v_boy = -747 N * 0.540 m/s = -405.08 N * m/s.

The momentum of the girl after she pushes off is denoted as   m_girl * v_girl, where m_girl is the mass of the girl and v_girl is her velocity.

The principle of conservation of momentum requires that the total momentum of the two-person system before and after the push off must be the same, hence we have:

m_boy * v_boy + m_girl * v_girl = 0

Substituting in the values for m_boy and v_boy, we find:

-405.08 N * m/s + m_girl * v_girl = 0

the initial speed of the bullet as it was fired horizontally into the wooden block resting on a horizontal surface is 265m/s.

A conservation law states that the total linear momentum of a closed system remains constant through time, regardless of other possible changes within the system.

Given, A 5.00g bullet is fired horizontally into a 1.20kg wooden block resting on a horizontal surface.

In our case,

Mass of bullet = 5 gram = 0.005 kg

Mass of wooden block = 1.2 kg

the initial velocity of block = 0

Kinetic friction = 0.20

First, we get the velocity of the Wood.

From Conservation of Energy:

1/2m v² = μ mgs

v = √(2 μgs)

Where v is the velocity of the block,

μ is the coefficient of kinetic friction,

s is the displacement of the bullet

g is the acceleration due to gravity (9.81)

v = √(2 *0.2*9.81 * 0.31)

v = 1.1 m/s

so, the velocity of the wooden block after the collision will be 1.10 m/s

Now, we determine the velocity of the bullet. Using Conservation of Momentum.

m₁v₁ + m₂v₂ = MV

0.005 *v + 0 = (1.20 + 0.005) * 1.1

v = 1.325/0.005

v = 265 m/s

Therefore, the initial speed of the bullet as it was fired horizontally into the wooden block resting on a horizontal surface is 265m/s.

0.00455 moles of air must be released from the tire to restore the pressure to 210 kPa at 50 degrees C.

The pressure rise in a 0k tire when the air temperature rises from 25 degrees C to 50 degrees C can be calculated using the ideal gas law. The formula is

PV = nRT

where P is the pressure, V is the volume, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature. In this case, the temperature is rising from 25 degrees C to 50 degrees C, so the pressure will increase with the temperature.

By plugging these values into the equation, we can calculate that the pressure increase is 45.5 kPa.

To restore the pressure to its original value of 210 kPa at 50 degrees C, we need to bleed off the amount of air equal to the pressure increase. This is equal to 45.5 kPa, or 0.00455 moles.

For part 4 after solving the equation the the rotation rate is 0.74 rev/s.

What is rotation rate?

Rotation rate is the angular velocity of a body or object in a circular motion. It is typically measured in rotations per minute (RPM) and is the number of times a full rotation is completed in one minute.

Part 1 of 4 - Conceptualize: Look carefully at the figure and imagine you are the astronaut sitting in the seat at the far right. As the centrifuge rotates, you are experiencing an acceleration toward the center of the device.

The faster the centrifuge spins, the larger is that acceleration. The problem is asking for a rotation rate, measured in revolutions per second. Because the period of circular motion is the number of seconds per revolution, we see that the rotation rate will be the inverse of the period.

Part 2 of 4 - Calculate: To calculate the rotation rate, we need to find the period of the motion. The period of circular motion is given by:

T = 2π√(L/2a)

Where L is the length of the centrifuge and a is the centripetal acceleration.

Part 3 of 4 - Calculate: In this problem, L = 59.0 ft, and a = 20.0g. Since gravitational acceleration is equal to 9.8 m/s2, we need to convert the acceleration from g to m/s2. We can do this by multiplying the acceleration by 9.8. Thus, a = 20.0g × 9.8 m/s2 = 196.0 m/s2. Substituting the numerical values into the equation, we get:

T = 2π√(59.0 ft/2 × 196.0 m/s2) = 2π√(29.5 ft × 9.8 m/s2) = 2π√(291.1 m2/s2) = 2π√(291.1) s = 5.15 s

Part 4 of 4 - Calculate: Since the period of circular motion is the number of seconds per revolution, the rotation rate is equal to the inverse of the period. Thus, the rotation rate is:

Rotation rate = 1/T = 1/5.15 s = 0.74 rev/s

The velocity of the ball before it hit the ground was (3.59 m/s, -3.32 m/s) in the horizontal and vertical direction

Explanation:

The velocity of the ball can be calculated using the equation of motion:

v^2 = u^2 + 2as,

where

u = initial velocity,

v = final velocity,

a = acceleration due to gravity (9.8 m/s^2),

s = vertical height fallen (0.86 m).

Solving for u:

u = sqrt(v^2 - 2as)

We know the final velocity, v = 0 (the ball lands on the ground and stops), so

u = sqrt(2as) = sqrt(2 * 9.8 * 0.86) = 3.32 m/s.

The direction of the velocity before it hit the ground can be determined using horizontal distance traveled and time of flight.

The time of flight, t, can be found using:

t = sqrt(2s/a) = sqrt(2 * 0.86 / 9.8) = 0.39 s.

The horizontal velocity, vx, can be found using:

vx = d / t = 1.4 / 0.39 = 3.59 m/s.

The resultant force acting on the gate is equal to zero, the gate will not rotate and the pin can be placed at any location on the circumference of the gate.

To determine the placement of the pin on the circular gate, we need to consider the forces acting on the gate when the water reaches a height h = 10 ft.

When water reaches a height h = 10 ft, the gate is subjected to two types of forces: (1) buoyant force and (2) weight of the gate. The buoyant force acts upwards and is equal to the weight of the fluid displaced by the gate. The weight of the gate acts downwards and is equal to the mass of the gate multiplied by the acceleration due to gravity (g).

Let's assume that the gate has a uniform thickness and its density is equal to the density of water (ρ). Then, the volume of the gate can be calculated as follows:

V = (π/4) * d² * t

where d is the diameter of the gate and t is its thickness. The mass of the gate can be calculated as follows:

m = ρ * V

The buoyant force can be calculated as follows:

F_b = ρ * g * V

The weight of the gate can be calculated as follows:

F_w = m * g

The net force acting on the gate can be calculated as the difference between the buoyant force and the weight of the gate:

F_net = F_b - F_w = ρ * g * V - m * g = (ρ - ρ) * g * V = 0

Since the net force is equal to zero, the gate will not rotate and the pin can be placed at any location on the circumference of the gate.

The tension in the cord will be 6.99 N. To solve this problem we will refer to the laws of Mersenne. Mersenne's laws are regulations relating to the frequency of oscillation of a stretched string or monochord, helpful in musical tuning and musical instrument building.

This law suggests that the velocity in a string is directly proportional to the root of the applied tension and inversely proportional to the root of the linear density, that is,

v = √T/μ

Here,

v = Velocity

μ = Linear density ( mass per unit length)

T = Tension

Rearranging to find the Period we have that

T = v²μ

T = v²(m/L)

As we know that speed is equal to displacement in a unit of time, we will have to

T = (L/t)² (m/L)

T = (7.3/0.72)² (0.50/7.3)

T = 6.99 N

Therefore, the tension in the cord will be 6.99 N.
