If the velocity of a particle is nonzero, can its acceleration be zero? Explain

How can acceleration be zero if velocity is non zero?

Find the magnitude and direction of the vector represented by the following pairs of components: (a) A. = -8.60 cm, Ay = 5.20cm; (b)A.= -9.70m,Ay = -2.45m; (c) A. = 7.75krn, Ay = -2.70krn.

Does any one know about a method to find magnitude and direction of vector pairs?

Suppose you remove two eggs from the refrigerator, one hard-boiled and the other uncooked. You wish to determine which is the hard-boiled egg without breaking the eggs. This can be done by spinning the two eggs on the floor and comparing the rotational motions. Which egg spins faster? Which rotates more uniformly? Explain.

First time, its in my knowledge that it can be known without breaking.

"How could you increase the entropy of 1mol of a metal that is at room temperature? How could you decrease its entropy?"

Determind entropy and let me know as well.

Is it possible to change the translational kinetic energy of an object without changing its rotational energy?

If yes, how? If not, why not?

Must an object be rotating to have a nonzero moment of inertia?

Can a static object have nonzero moment of inertia?
