You are helping your friend move a new refrigerator into his kitchen. You apply a horizontal force of 280 N in the positive x direction to try and move the 63 kg refrigerator. The coefficient of static friction is 0.55.

The photo scale at point A is approximately 1:19,720.

The local coordinates of point A are approximately

{xA = 78898;

yA = 99751.85} meters.

To determine the photo scale at point A and the local coordinates of point A, we can use the principles of photogrammetry.

a. The photo scale at point A can be calculated using the following formula:

Photo Scale = (Focal Length / Flying Height)

Given:

Focal Length = 152 mm

= 0.152 m

Flying Height = 3000 m

Photo Scale at point A = (0.152 m / 3000 m)

= 0.00005067

Therefore, the photo scale at point A is approximately 1:19,720.

b. To determine the local coordinates of point A, we need to use the principle of collinearity. This principle states that corresponding points in the object space (terrain) and the image space (photograph) are collinear with the perspective center (principal point of the photograph).

Using the local coordinates of the photo principal point (xP = 78898;

yP = 99752) and the photo scale, we can calculate the local coordinates of point A as follows:

Local x-coordinate of point A = xP

Local y-coordinate of point A = yP - (Photo Scale * (Flying Height - Terrain Elevation of A))

Given:

Terrain Elevation of A = 50 m

Local x-coordinate of point A = 78898

Local y-coordinate of point A = 99752 - (0.00005067 * (3000 - 50))

Calculating the values:

Local x-coordinate of point A = 78898

Local y-coordinate of point A = 99752 - 0.1500517

Local x-coordinate of point A = 78898

Local y-coordinate of point A = 99751.8499483

Therefore, the local coordinates of point A are approximately

{xA = 78898;

yA = 99751.85} meters.

Explanation:

Now

Look at it this way. This box is in equilibrium... Meaning forces around balanced out.

Now...

The Earth's pull on it is 98N

What Minimum external forces is needed to pick this up....

Now... The Minimum Force is 98N

Why?

Since This Box is under the influence of gravity...

Gravity is acting as a resistance

If you apply a force less than 98N... Let's say 50N on this box... It won't budge because your applied force is less than the resisting force on it(98N).

So We need a force ≥98. So the least force is 98N. Nothing below this will move the Box

When a 1,500 kg car hits a brick wall with a force of 60.0 N in 1.75 s, the change in the momentum of the car is 105 kg.m/s.

A 1,500 kg car (m) hits a brick wall with a force of 60.0 N (F) in 1.75 s (t). We want to determine the change in the momentum of the car.

The impulse-momentum theorem states that the change in momentum (Δp) of an object equals the impulse (I) applied to it.

This is represented through the following formula.

I = Δp

F × t = Δp

Δp = F × t = 60.0 N × 1.75 s = 105 kg.m/s

The term that you are referring to is an action potential. An action potential is a rapid and brief wave of positive electrical charge that sweeps down the axon of a neuron.

It is initiated by a depolarization of the cell membrane and results in the transmission of an electrical signal from one neuron to another.

Action potentials are a crucial part of the nervous system and are responsible for a wide range of behaviors and functions, including movement, sensation, and cognition.

The process of generating an action potential involves a series of changes in the electrical potential across the neuron's cell membrane. Normally, the neuron's membrane has a resting potential, which is a stable negative charge inside the cell compared to the outside.

This resting potential is maintained by the balance of ions, such as sodium (Na+), potassium (K+), and negatively charged proteins, across the membrane.

When a neuron receives a stimulus, it can cause a brief depolarization of the cell membrane. Depolarization is a change in the electrical potential, resulting in a temporary reversal of the charge across the membrane.

This depolarization triggers the opening of voltage-gated ion channels, primarily sodium channels, in the neuron's membrane.

When a rubber cylinder is rubbed with a piece of wool, the cylinder accumulates a negative charge. The charge on the wool would be positive. This occurs as both the rubber and wool exhibit the triboelectric effect.

When two materials rub against each other, electrons are transferred from one to another, causing one material to become positively charged while the other becomes negatively charged. However, the direction of the charge transfer depends on the materials involved. Certain materials, such as wool and rubber, have a greater ability to hold on to electrons, which means that they will accumulate more electrons and become negatively charged.

As a result, the rubber cylinder acquires a negative charge when it is rubbed with wool, while the wool acquires a positive charge. This is because wool has a higher tendency to lose electrons, causing it to become positively charged.The transfer of charge can be explained by Coulomb's law, which states that like charges repel each other, while opposite charges attract each other. The charges on the wool and rubber cylinder will cause them to attract each other, since they have opposite charges.

Answer:

The normal force exerted on the skateboarder by the bump is less than the weight of the skateboarder

Explanation:

The given parameters are;

The location of the skateboarder = The top of the circular bump

The direction of motion of the skateboarder = Rightward

Therefore, given than the skateboarder has both horizontal angular motion (moving rightward) and vertical angular motion (over the bump), The effect of the weight of the skateboarder on the ground is reduced by the centripetal forces acting on the skateboarder and the normal force exerted on the skateboarder by the bump is equal to the reduced weight and is therefore less than the actual weight of the skateboarder.

The normal force exerted on the skateboarder is less than the weight due to the effect of centripetal force.

Given data:

The position of skateboarder is at top of the circular bump.

And direction of motion of Skateboarder is towards rightward.

Since, the skateboarder is undergoing the motion over the circular path, then it will have both horizontal angular motion (moving rightward) and vertical angular motion (over the bump).

The effect of the weight of the skateboarder on the ground is reduced by the centripetal forces acting on the skateboarder and the normal force exerted on the skateboarder by the bump is equal to the reduced weight and is therefore less than the actual weight of the skateboarder.

Thus, we can conclude that the normal force exerted on the skateboarder is less than the weight due to the effect of centripetal force.

Inverse relationships are common in nature. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

Explanation:

Two ways to decrease the electric force between two charged objects:

As a result of their electric charge, particles or objects are attracted to or repelled by the Coulomb force, also known as electrostatic force or Coulomb interaction. Charles-Augustin de Coulomb, a French scientist who published the findings of an experimental inquiry into the proper quantitative description of this force in 1785, gave the electric force its name. The electric force is one of the fundamental physical forces.

Positive or negative electric charges that are similar to one another repel one another in a straight line between their centers. Positive and negative charges that are opposite each other are drawn together along a straight line connecting their centers.

Answer:

\(0.361\ \text{m}\)

Explanation:

\(f_s\) = Frequency of source = 375 Hz

\(\Delta f\) = Difference between the maximum and minimum sound frequencies = 2.75 Hz

v = Speed of sound in air = 343 m/s

T = Time period = 1.8 s

\(v_m\) = Maximum speed of the microphone

We have the relation

\(\Delta f=2f_s\dfrac{v_m}{v}\\\Rightarrow v_m=\dfrac{\Delta fv}{2f_s}\\\Rightarrow v_m=\dfrac{2.75\times 343}{2\times 375}\\\Rightarrow v_m=1.26\ \text{m/s}\)

Amplitude is given by

\(A=\dfrac{v_mT}{2\pi}\\\Rightarrow A=\dfrac{1.26\times 1.8}{2\pi}\\\Rightarrow A=0.361\ \text{m}\)

Answer:

800 Newtons.

Explanation:

Work is defined as the force applied to an object multiplied by the distance over which the force is applied. The formula for work is W = F x d.

In this case, the force required to lift the box is equal to the work done divided by the distance.

F = W / d

F = 800 J / 5 m

To convert Joules to newtons, we need to use the relation 1 Joule = 1 Newton x Meter

F = 800 N

So the box weighed 800 Newtons.

When two disks of identical mass but different radii are brought slowly together while spinning on frictionless bearings at the same angular speed but in opposite directions, the resulting frictional force increases due to the increase in angular velocity caused by the change in moment of inertia of the system.

Angular momentum is given by the equation L = Iω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity. The moment of inertia of a rotating object depends on its mass and how that mass is distributed around its axis of rotation.

In this scenario, the disks have the same mass but different radii. The moment of inertia of a disk is given by the equation I = (1/2)mr^2, where m is the mass and r is the radius. Since the disks have the same mass, their moments of inertia will be proportional to their radii squared.

Since the disks are rotating in opposite directions, the change in angular momentum due to their interaction will be the sum of their individual angular momenta. The change in angular momentum is given by ΔL = Lfinal - Linitial.

As the disks are brought closer, their moments of inertia decrease. Therefore, in order to conserve angular momentum, the angular velocity ω will increase. This increase in angular velocity results in an increase in frictional force between the disks.
