Answer:small barrel gun
Explanation:
Given
Muzzle velocity of bullet is greater in short barrel gun as compared to larger barrel gun
acceleration is given by change in velocity with respect to time

In case of short barrel bullet time taken by bullet to reach its muzzle velocity is less therefore acceleration of small barrel bullet is more compared to long barrel bullet.
Answer:

Explanation:
Recall that the formula for an inductance (L) for coil on N turns, are A and current I is given by:

Then, for the first coil we have;

and for coil 2 we have:

then, the quotient L1/L2 can be written as:

You've described two (2) axes of motion.
The third one would have been up-and-down.
Well it depends it has to be some kind of metal material if not then it will not pick it up Hope this helps:)
