Answer:
Correct option C. "The two objects stick together"
Explanation:
There are two types of collision. First one is elastic collision and other one is inelastic.
In inelastic collision, the linear momentum before and after the collision is same but the kinetic energy after the collision is not constant. It is used in the form of heat, light etc.
For an inelastic collision, two objects after collision sticks together and move with a common speed. It is one of the important factor for inelastic collision.
Answer:
1. False
2. True
3. True
Explanation:
1- False —> The relation between electric potential and electric field is given such that
Therefore, for a uniform E field, electric potential is linearly proportional to the distance.
2- True —> The electric field lines always cross the equipotential lines perpendicularly.
3- True —> In order to be a potential difference, one source of electric field is enough. The electric potential will decrease radially according to the following formula:
There is no test charge in the formula, only the source charge. Even when there is no test charge, the potential difference between points in space can exist.
