What is it called when two or more bodies orbit at multiples of the same orbital period?

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:

D = 18 / 3 = 6 cm

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.

The electron would have a greater speed because it has a smaller mass. The moving particle has a greater speed when the collision occurs.

A collision is an event in which two or more objects come into contact with each other, resulting in a transfer of energy and/or momentum. Collisions can range from relatively mild, such as two cars lightly bumping into each other in a parking lot, to extremely energetic and destructive, such as two asteroids colliding in space or a high-speed train crash. The outcome of a collision depends on the relative velocity and masses of the objects involved, as well as any forces between them, such as friction or electrical forces.

In physics, collisions are often studied as a means of understanding the underlying laws of motion and the behavior of objects in motion. By analyzing the motion of objects before and after a collision, scientists can determine the changes in energy, momentum, and velocity that occur as a result of the collision. This information can be used to design safer vehicles, improve the accuracy of simulations, and gain a deeper understanding of the physical world.

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. The magnitude of the resulting vector can be calculated as the square root of the sum of the squares of the magnitudes of the two vectors.

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)

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.
