In this scenario, if you push the wall with a force of 38 N, the wall will push back on you with an equal and opposite force of 38 N. So, the wall would push on you with a force of 38 N.

According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction.

If object A exerts a force on item B, object B must respond with a force of same size and opposite direction. This rule reflects a natural symmetry: forces always occur in pairs, and one body cannot exert a force on another without also suffering a force.

According to the first law, an object's motion will not alter unless a force acts on it. According to the second law, the force acting on an object is equal to its mass multiplied by its acceleration. When two objects contact, they apply forces of equal magnitude and opposing direction to each other, according to the third law.

The magnitude of the weight that can be supported by the right side of the jack can be calculated using the equation:

w = (force) * (distance)

where force is equal to the weight density of the material times its volume and distance is equal to the difference in elevation.

Since weight is equal to mass times acceleration due to gravity, we can write:

w = m * g

where m is the mass and g is the acceleration due to gravity, 9.8 m/s^2.

So the weight that can be supported by the jack can be calculated as follows:

w = m * g

w = (density * volume * g) * (distance)

w = (density * volume * 9.8 m/s^2) * (2.4 ft)

Explanation:

Inertia. The physical law that states that objects in motion have a tendency to remain in motion also plays a role in keeping the planets in orbit.

The ball will go for a maximum height of roughly 62.25 feet.

Given that the acceleration due to gravity is 32 feet per squared second, we can integrate it with respect to t to calculate the velocity equation.

  a(t) = -32 ft/s²
  v(t) = ∫a(t) dt = ∫-32dt = -32t + C

The given initial velocity is 60 ft, so:

  v(t) = -32t + C
  v(0) = -32(0) + C
     C = 60

Thus, the formula for v(t) in this case is -32t + 60.

Since velocity is always 0 (zero) at maximum height, you can calculate the time needed for the ball to reach maximum height:

  v(t) = -32t + 60
    0 = -32t + 60
     t = 1.875 s

Put the time aside to calculate the formula for the distance equation.

  s(t) = ∫v(t) dt = ∫(-32t + 60)dt = -16t² + 60t + C

Now, since we have the initial distance/height at 6 feet, we can calculate the C for the formula above. Remember that the initial time is 0.

  s(t) = -16t² + 60t + C
  s(0) = -16(0)² + 60(0) + C
     6 = C

Thus, the calculation for distance is s(t) = -16t² + 60t + 6

Since we already found out the time needed to reach maximum height earlier, we can plug the number into the formula above:

        s(t) = -16t² + 60t + 6
s (1.875) = -16(1.875)² + 60(1.875) + 6

              ≈ 62.25 feet.

Using mirror's equation, The smallest diameter mirror in which the observer can just see the reflected edge of the coin is 6 cm.

We must compute the size of the mirror's produced image in order to identify the lowest diameter mirror that would allow the spectator to just view the coin's reflected edge.

We must first determine how far the picture is from the mirror. In order to compute this, use the mirror equation:

[tex]\frac{1}{f} = \frac{1}{d} + \frac{1}{d'}[/tex]

where f is the mirror's focal length, d and d' are the object's and image's distances from the mirror, respectively.

Since the mirror is flat, the focal length is determined by dividing the radius in half. Therefore, we may apply the formula:

[tex]f = \frac{R}{2}[/tex]

This results from substituting it into the mirror equation:

[tex]\frac{2}{R} = \frac{1}{3} + \frac{1}{d'}[/tex]

Calculating d':

[tex]d' = \frac{3R}{ (R-6) (R-6)}[/tex]

The mirror's diameter, D, is equal to 2R. As a result, the minimal diameter of the mirror, at which the spectator can only see the coin's edge reflected, can be calculated as follows:

[tex]D = 2R = \frac{2d' (R - 6)}{ 3}[/tex]

d' = 9, thus we can condense it to:

Gravity is an attractive force, meaning that it pulls objects towards each other. It is considered a relatively weak force compared to other forces in the universe, but its strength is proportional to the mass of the objects involved and the distance between them. Over large distances and for massive objects, gravity can be a very strong force.

The attractive force of gravity is caused by the masses of objects and the distance between them. According to Newton's law of universal gravitation, the strength of the gravity force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. The greater the masses of the objects and the closer they are to each other, the stronger the attractive force of gravity will be between them. This fundamental principle helps to explain why objects are pulled towards each other, creating the attractive force of gravity.

When white light moves from air into a different material, such as glass, it is refracted (bent) due to a change in speed produced by the difference in refractive index.

The explanation for the above answer is

Refraction is the bending of light as it travels through different media. White light slows down and bends when it transitions from the medium of air to another one, such as glass. Because glass has a higher refractive index than air, light penetrates glass at a different speed than it would outside of it.

As a result, at the point where the air and the glass meet, the light is refracted or twisted. Snell's law describes how the angle of incidence and the difference in refractive indices affect how much bending occurs. The functioning of lenses and prisms is based on the phenomenon of refraction, which is essential for many optical systems.

When the sheet of paper starts moving southeast at a constant speed, the motion of the ant relative to the table becomes a combination of two motions: the ant's original motion due east and the motion of the sheet of paper southeast.

To describe the motion of the insect relative to the table, we need to take into account both the ant's original motion and the motion of the sheet of paper. The ant's original motion due east at a constant speed can be represented as a vector, and the motion of the sheet of paper southeast can be represented as another vector. The sum of these two vectors represents the motion of the ant relative to the table.

Mathematically, if we represent the ant's original motion due east as a vector with magnitude and direction, and the motion of the sheet of paper southeast as a vector with magnitude and direction , then the motion of the ant relative to the table can be represented as the sum of these two vectors.

In this case, the ant's original motion due east and the motion of the sheet of paper southeast are both at right angles to each other, so the sum of the two vectors can be represented using the Pythagorean theorem.

If a person walks up the moving escalator with a speed of 0.49 m/s relative to the escalator, it will take 26 seconds to get to the top.

Velocity and speed describe how quickly or slowly an object is moving. We frequently encounter circumstances when we must determine which of two or more moving objects is going faster. If the two are traveling on the same route in the same direction, it is simple to determine which is quicker. It is challenging to identify who is moving the fastest when their motion is in the other direction. The concept of velocity is useful in these circumstances. Learn what velocity means, how it is measured, an example of velocity, and how it differs from speed in this article.

The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction. Since it is a vector quantity, the definition of velocity requires both magnitude (speed) and direction.

The time it takes a person to walk up the escalator can be calculated using the equation:

t = d / (v_p + v_e)

where,

d = 13 m (length of the escalator)

v_p = 0.500 m/s (velocity of the person relative to the ground)

v_e = 0 (velocity of the escalator relative to the ground, since the person is walking against it)

Now, we get:

t = 13 / (0.500 + 0) = 26 s

As you speed up while driving through the rain, the angle of the rain relative to the horizontal that you observe from inside the car will become more perpendicular. This is because the raindrops are being deflected by your car's movement, making them appear to be coming straight down.

When you're driving through the rain, the raindrops are initially hitting the windshield of your car at an angle. If you speed up, the velocity of your car increases, and this increases the deflection of the raindrops as they hit your windshield. The result is that the angle at which the raindrops hit the windshield appears to be more perpendicular, making it appear as though the rain is falling straight down. This is simply an optical illusion caused by the increased deflection of the raindrops due to your car's movement.
