Adockworker loading crates on a ship finds that a 28-kg crate, initially at rest on a horizontal surface, requires a 74-n horizontal force to set it in motion. however, after the crate is in motion, a horizontal force of 53 n is required to keep it moving with a constant speed. find the coefficients of static and kinetic friction between crate and floor.

the results is a decrease in air temperature with an increase of altitude.

explanation:

electric field is a function of 1/r^2

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