7) Calculate the force of gravity between the earth and the satellite: F, -Gm. me/r?. (G = 6.7 x 10-11 Nm2/kg. Mass of earth = 6.0 x 1024 kg.) 8) Calculate the acceleration of the satellite using Newton's 2nd Law. a - F/m. a - Gx (mass of earth) /radius? (Mass of earth = 6.0 x 1024 kg.)

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.
