Work done = Potential Energy = (mg)h
mg = weight of the ball
= 1000 N * 2.5 m = 2500 Joules.
The work done during the 5 second is 2500 Joules.
Answer:
<em>Friction, force that resists the sliding or rolling of one solid object over another.</em>
A is the correct answer. It is an example of mutualism, where both species involved benefits.
Answer:
Net force of the object is zero.
Explanation:
When an object is going to the left at constant velocity, this means there is no acceleration. Hence, no force. Had there been force,acceleration had been inevitable. Therefore, we can say that when an object moves with a constant velocity and in same direction, the net force on the object is zero.
The kelvin temperature/scale i think
