Solar cells convert solar energy into electrical energy

A photovoltaic cell, commonly called a solar cell or PV, is the technology used to convert solar energy directly into electrical power. Solar-powered photo-voltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. The solar panels collect particles of light, called photons, which knock electrons free from their atom hosts.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
