Given the graph below, the resistance of the wire in Ohms is: a 0.25
b 4
c 3.75
d 0

Distinguish between a transverse wave and a longitudinal wave.

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?
