Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
