a block with a mass of 3.8 kilograms slides with a velocity of 6 m/s on a frictionless surface. it hits a horizontal spring with a spring constant of 200 n/m. how much work does the block do on the spring?

a. is the answer because they are not shared

double the distance = divide strength by 4

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
