Answer:
The magnitude of the force of friction equals the magnitude of my push
Explanation:
Since the crate moves at a constant speed, there is no net acceleration and thus, my push is balanced by the frictional force on the crate. So, the magnitude of the force of friction equals the magnitude of my push.
Let F = push and f = frictional force and f' = net force
F - f = f' since the crate moves at constant speed, acceleration is zero and thus f' = ma = m (0) = 0
So, F - f = 0
Thus, F = f
So, the magnitude of the force of friction equals the magnitude of my push.
Answer:
Explanation:
Wind is caused by the uneven heating of the atmosphere by the sun, variations in the earth's surface, and rotation of the earth. ... Wind turbines convert the energy in wind to electricity by rotating propeller-like blades around a rotor. The rotor turns the drive shaft, which turns an electric generator

Answer: Well you didn't give any answers so my guess would be it depends how much force you put into it and where you throw it.
Explanation:
B) The wall pulls with a force of 250 N against the force
Explanation:
We can answer this question by using Newton's third law of motion, which states that:
<em>"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"</em>
In this situation, the student is applying a force of 250 N on the wall. We can identify this force as the action. Therefore, this means (according to Newton's third law) that the wall will also apply a force (the reaction) of equal magnitude (so, 250 N), in the opposite direction to the original force.
Therefore, the correct statement is
B) The wall pulls with a force of 250 N against the force
