Answer:
<h3><u>If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.</u></h3>
Answer: e ven though the man exerts force on the wall , the wall does not move. Work done = force applied * displacement and since the displacement of the wall is zero. , work done is also zero
Explanation:
Voltage - An electromotive force or potential difference expressed in volts.
Current - A flow of electricity which results from the ordered directional movement of electrically charged particles.
Answer:
True
Explanation:
If the object moves at constant speed then it means that the velocity changes instantaneously although the speed does not change. The change in velocity brings out acceleration and where there is a mass that undergoes acceleration there must be an external resultant force. this force is centripetal force.
