In a collision, a vehicle that rebounds off the object it strikes experiences the same force as it exerts on that object, assuming the time is the same in both situations.
true
false

True

Explanation:

The exerted force in both cases will be same because the object is same in both scenarios.The only difference is that rebounds energy will be lesser in second case. The reason behind this reduction is that some part of rebounds energy will be used in deforming the shape of the car. Hence, the given statement is true.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
