Translational motion is a type of motion in which objects move with a change in position. The situation that best shows the translational motion is leaf blowing in the field.
Translational Motion:
It is a type of motion in which objects move with a change in position.
For example- leaf blowing in the field.
- Coin spinning on the desk does not change its position.
- A car in the parking lot with running engine does not change its position.
- Standing in feet is not any kind of movement.
Therefore, the situation that best shows the translational motion is leaf blowing in the field.

Answer:
The answer to the question is A.
Explanation:
The definition of moment is Force multiplied the distance to the point of interest.
So the external moment at point O is equal to ⇒ EMо= F×d
Knowing the definition of moment of inercia (I) and a newtonian Force ( m.a)
We can say that te moment of the externals force at point O is EMо= IGa
Because the rotation of a body in a inmovil point is implicated by the moment of inercia an the action of the gravity in that moment.
Answer:
an 85 kg person run to equal the kinetic energy of an 8.0 g bullet fired at 410 m/s? The speed is, it might be argued,
v=4.0m/s
Explanation:
Typically, the mathematical formula for kinetic energy is as follows:
KE=
K.E= kinetic energy
M=mass
V= speed
so,
KE=1/2*0.008*(420)*420
K.E=672.4J
Therefore,
v*v=672.4/85
v*v=15.821
v=4.0m/s
Therefore
v=4.0m/s
What is Kinetic Energy?
The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.

The resulting positive amplitude of the two waves after the superimposition is 4.30 cm.
<h3>
Amplitude of the waves</h3>
The amplitude of the waves is the maximum displacement of the wave. This is the vertical position of the wave measured from the zero origin.
After the superimposition of the two similar waves, the resulting amplitude will be less than the initial amplitude of the wave with the highest vertical height since the superimposition creates destructive interference.
Resulting amplitude of the two waves is calculated as;
A = 5.4 cm - 1.10 cm
A = 4.30 cm
Thus, the resulting positive amplitude of the two waves after the superimposition is 4.30 cm.

Just because there is more mass in a certain substance doesn’t mean it’s density will change. In this case, water, will not change density simply because there is more of it. I.e the ocean. The bottom of the ocean may have more pressure to it because of the weight of the water above it but if you were to take a cup of it and take it to the surface it wouldn’t sink.
