Determine the force of gravitational attraction between the earth and a 60 kg physics student if the student is standing at sea level, a distance of 9 m from earth's center. The mass of the earth is 6x10^24 kg.

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

Contrast the force of gravity between these pairs of objects: 1-kg mass and a 2-kg mass that are 1 m apart; a 1-kg mass and a 2-kg mass that are 2 m apart; and two 2=kg masses that are 1 m apart. i dont understand.

Mark creates a graphic organizer to review his notes aboutelectrical force. which labels belong in the regions marked x and y?
