When you release the mass, what do you observe about the energy?
anygoal [31]

Explanation:

Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale.

A train is moving with a velocity of 70 km/h.
hodyreva [135]

Answer:

B: It is moving north.

We are told that a train is moving with a velocity of 70 km/h.

Now, we are also told that the positive direction is north.

This means that the train is moving in the northern direction.

We can't say if it is speeding up or not because we are not given the acceleration.

Thus, option B is correct
