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
R =√52,913.7
R = 230.03 km/hour

Three blocks in contact with each other are pushed across a rough horizontal surface by 63 N force as shown. The acceleration of gravity is 9.8 m/s 2 kg kg 2.5 kg K = 0.1 If the coefficient of kinetic friction between each of the blocks and the surface is 0.1, find the magnitude of the force exerted on the 9 kg block by the 2.5 kg block_ Answer in units of N.
The 2.5 kg block pulls on the 9 kg block with an 87.2 N force.
Newton's Third Law, often known as the law of action and reaction, can be used to determine the force that the 2.5 kg block exerts on the 9 kg block. The force applied to the 9 kg block is equivalent to, but applied in the opposite direction from, the force applied to the 2.5 kg block. Since they are in touch, the force of friction operating on the 9 kg block is equal to the force of friction acting on the 2.5 kg block.
Calculating the friction force is as simple as multiplying the normal force, or weight of the object, by the coefficient of friction:
Step 1: Determine the normal force or weight of the object. The weight of a 9 kg object can be calculated as 9 kg x 9.8 N/kg = 87.2 N.
Step 2: Determine the coefficient of friction. In this case, the coefficient of friction is 0.1.
Step 3: Calculate the friction force by multiplying the normal force by the coefficient of friction.
Friction force = Normal force x Coefficient of friction
= 87.2 N x 0.1 = 8.72 N.

The restoring force and acceleration are always in the same direction for a simple harmonic oscillator.
A simple harmonic oscillator is what?
A driven or dampened oscillator is known as a simple harmonic oscillator. It typically consists of a mass "m" that is pulled in the direction of the point x = 0 by a single force "F" that solely depends on the body's position "x" and a constant "k."
Consider a straightforward pendulum that displays SHM at low displacements. The location vector points upward while the acceleration and velocity vectors point downward during the downswing. The acceleration vector points downward while the location and velocity vectors point upward during an upswing. Therefore, unless they are both 0 at equilibrium, the acceleration always points in the opposite direction to the position vector. The acceleration and force of restoration are always in same direction .

Which of the following is the correct statement?(a) Throughout its motion, the ball's velocity is zero(b) At the highest point in its motion, the ball's acceleration is zero(c) At the highest point in its motion, the ball's velocity is zero(d) Throughout its motion, the ball's acceleration is zero(e) At the highest point in its motion, the ball's velocity and acceleration.
The correct statement is (c): At the highest point in its motion, the ball's velocity is zero.
This is due to the fact that when anything is thrown straight up, it has a starting velocity and then accelerates as it descends towards the Earth. Its velocity is equal to zero as it reaches its highest point (due to the gravitational pull of the Earth). The ball's acceleration varies continuously as it travels because it accelerates towards the Earth when it is travelling upward and decelerates when it is travelling downward.
The ball is briefly at rest, and the only force acting on it is the gravitational pull of the Earth, therefore at its fastest point in motion, the acceleration is equal to zero.

Starting with an energy balance on a rectangular volume element, derive the one- dimensional transient heat conduction equation for a plane wall with constant thermal conductivity and no heat generation.
The transient heat conduction equation for a plane wall with constant thermal conductivity and no heat generation can be derived from the energy balance equation for a rectangular volume element.
Consider a plane wall with constant thermal conductivity, k, and no heat generation. Let's assume that the wall is at temperature T at time t and T + ΔT at time t + Δt. The energy balance equation for a rectangular volume element of the wall can be expressed as:
ΔQ/Δt = -kA(ΔT/Δx), where
ΔQ/Δt is the rate of heat transfer into the volume element k is the thermal conductivityA is the cross-sectional area of the wallΔT/Δx is the temperature gradient across the wall.Rearranging the equation:
ΔT/Δt = -(k/A)(ΔT/Δx)
The above equation represents the one-dimensional transient heat conduction equation for a plane wall with constant thermal conductivity and no heat generation.
This equation can be further simplified by using the thermal diffusivity, α, which is defined as:
α = k / (ρCp) where,
ρ is the density of the material Cp is the specific heat capacity.Substituting α into the equation:
ΔT/Δt = -α(ΔT/Δx^2)

Answer:
Work = 1243.17 J
Explanation:
Work = Force × Distance × Cosine (Angle)

A person jumps off a diving board 4.1 mm above the water's surface into a deep pool. The person's downward motion stops 2.3 mm below the surface of the water. Estimate the average deceleration of the person while under the water.
The average deceleration of the person while underwater can be estimated as 875 m/s².
To calculate the average deceleration, we need to find the change in velocity over the change in time. The change in velocity can be calculated as the initial velocity (which is assumed to be zero) minus the final velocity, which is the velocity just before the person stops moving downward. The change in time can be found by subtracting the starting height from the stopping height.
Starting height = 4.1 mm = 4.1 × 10⁻³ m
Stopping height = 2.3 mm = 2.3 × 10⁻³ m
Change in velocity = final velocity - initial velocity
Change in velocity = 0 m/s - (-√(2gh))
Change in velocity = √(2gh)
where g is the acceleration due to gravity (9.8 m/s²) and h is the height (4.1 mm)
Change in velocity = √(2 × 9.8 × 4.1 × 10⁻³)
Change in velocity = √(79.26 × 10⁻³) = 8.9 m/s
Change in time = final time - initial time
Change in time = 0 s - (stopping height - starting height)
Change in time = (starting height - stopping height)
Change in time = 4.1 × 10⁻³ - 2.3 × 10⁻³ = 1.8 × 10⁻³ s
Change in time = 1.8 × 10⁻³ s
Average deceleration = change in velocity / change in time
Average deceleration = √(2 × 9.8 × 4.1 × 10⁻³) / (h2 - h1)
Average deceleration = 8.9 / (1.8 × 10⁻³)
Average deceleration = 875 m/s²

Block 1 is moving to the left and strikes Block 2, which is at rest. 100% of the momentum of Block 1 transfers to Block 2. So Block 2 now moves to the left at 4 m/s (you didn't specify a unit) and Block 1 comes to a complete stop and is now at rest.
if a 12 V battery is connected to the circuit shown, and R1 and R2 are EACH 2 ohm resistors; what must be the resistance of R4 be if R3 is 4 ohms and the total current is 2 amp?
Answer:
Explanation:
First find the total resistance of the combination circuit:
R = V/I = 12 V / 2 A = 6 Ω
6Ω = R1 + R2 + 1/(1/R3 + 1/R4)
6Ω = 2Ω + 2Ω + 1/(1/4 + 1/R4)
2Ω = 1/(1/4Ω + 1/R4)
2Ω(1/4Ω + 1/R4) = 1
(1/4 + 1/R4) = 1/2
1/R4 = 1/4
R4 = 4Ω
Note: R1 and R2 are in series, so you just add them together. But R3 and R4 are in parallel, so Req = 1/R3 + 1/R4
A thin layer of liquid with thickness h has a laminar velocity profile of u=Uo(2yh−y2h2) where Uo is the surface velocity and y is the distance from the wall along the thickness of the liquid. If the liquid thickness is 0.5 in and the flow rate per foot of channel is 1.25 gal/min, determine the surface velocity Uo
The surface velocity is approximately 2.07 m/s.
The average velocity of the liquid flow per unit depth,
Q/A = 1.25 [gal/min]/[1 ft x 0.5 in x (1/12) ft/in] = 10 [ft/min]
where Q is the flow rate and A is the cross-sectional area of the channel.
Use the laminar velocity profile to determine the velocity at the center of the channel (y=0),
u(y=0) = Uo(2(0) - 0^2)/(2h) = 0
Since there is no slip at the wall, the velocity at y=h/2,
u(y=h/2) = Uo(2(h/2) - (h/2)^2)/(h)
= Uo(2-h/2)
= 2Uo - Uh/2
Equating this to the average velocity,
2Uo - Uh/2 = 10 [ft/min]
Solving for Uo = (10 + Uh/2)/2
Uh = Ahu(y=h/2) = AhUo(2-h/2)/(h) = A*Uo(2-h/2)
Substituting A = 1 [ft^2] and h = 0.5 [in] = 0.042 [ft], we get:
Uh = Uo(2-0.042/2) = 0.979Uo
Uo = (10 + 0.979Uo/2)/2
Uo = 6.8 [ft/min] or 2.07 [m/s]

An electric field is a physical field that surrounds electrically charged particles and acts as an attractor or repellent to all other charged particles in the vicinity. It can also refer to a system of charged particles' physical field.
When charge is present in any form, every point in space has an electric field associated with it. The value of E, often known as the electric field strength, electric field intensity, or just the electric field, expresses the strength and direction of the electric field.
[tex]$$The $\mathrm{x}$ component of $\vec{E}_q$ is given as:$$\begin{aligned}\vec{E}_{q, x} & =E_q \cos 45^{\circ} \hat{x} \\& =k \frac{\left|-1.1 \times 10^{-9}\right|}{1.25 \times 10^{-3}} \times \frac{1}{\sqrt{2}} \hat{x}\end{aligned}$$And its y component is given as:$$\begin{aligned}\vec{E}_{q, y} & =-E_q \sin 45^{\circ} \hat{y} \\& =-k \frac{\left|-1.1 \times 10^{-9}\right|}{1.25 \times 10^{-3}} \times \frac{1}{\sqrt{2}} \hat{y}\end{aligned}$$[/tex]
[tex]$$Therefore, the net electric field at the location of $q_a$ is given as:$$\begin{aligned}\vec{E} & =\vec{E}_b+\vec{E}_c+\vec{E}_{d, x}+\vec{E}_{d, y}+\vec{E}_{q, x}+\vec{E}_{q, y} \end{aligned}[/tex]

[tex]\begin{aligned}& =\left(9 \times 10^9\right) \times 10^{-9} \times(-2572.13 \hat{x}+2572.13 \hat{y}) \\& =23149.17 \times(-\hat{x}+\hat{y}) \mathrm{N} / \mathrm{C}\end{aligned}[/tex]
[tex]$And its magnitude is given by:$$\begin{aligned}|\vec{E}| & =23149.17 \times \sqrt{1^2+1^2} \\& =23149.17 \times \sqrt{2} \\& =32737.87 \mathrm{~N} / \mathrm{C}\end{aligned}$$[/tex]
Thus, the magnitude of the electric field, in newtons per coulomb, at the location of qa in the figure is 32737.87 N/C.

find an expression for the magnitude of the electric field that enables the block to remain at rest.
To keep the block at rest, an electric field with a magnitude equal to the gravitational force divided by the block's charge is required.
What is magnitude?A physical quantity's magnitude can be used to gauge its size or strength, such as in the case of a vector. The term "magnitude" in the context of an electric field refers to the field's amplitude.
The "equilibrium electric field" is the electric field needed to hold an object still. A force will be applied to a charged object in an electric field, either in the direction of or away from the source of the field. The net force must be zero in order to maintain the item at rest, which necessitates counteracting the electric field's force with another force.
E = k * q / d2, where k is the Coulomb constant, q is the charge on the object, and d is the separation between the item and the field source, can be used to calculate the size of the electric field necessary for equilibrium. According to this equation, the electric field is inversely proportional to the square of the distance between the item and the field source and directly proportional to the charge on the object.
As a result, if an object is charged and placed in an electric field, the size of the field needed to keep the object at rest will depend on the object's charge and the distance between it and the field source.

According to this equation, the electric field is inversely proportional to the square οf the distance between the item and the field source and directly proportional to the charge on the οbject.
As with a typical inclined plane problem, we need tο find the compοnent of the gravitational fοrce parallel to the incline.
That is
[tex]\mathrm{ m \times g\times sin(\theta) }[/tex]
For the blοck to remain stationary, we set this equal to the coulοmb force
[tex]\mathrm{ qE = m \times g\times sin(\theta) }[/tex]
since E is parallel to the incline,
sοlving for E, we find the answer tο part a:
[tex]\mathrm{ E = \dfrac{m \times g\times sin(\theta) }{q} }[/tex]
Thus, an expression fοr the magnitude οf the electric field that enables the block tο remain at rest is:
