A box is being pushed but two stellar science students, one on each side of the box. Peter is pushing box with a force of 10 N to the left. Josh is pushing the box with a force of 15 N to the right. Who is the stronger individual and what is the net force and direction on the box?

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.

A20 cm long spring is attached to a wall. the spring stretches to a length of 22 cm when you pull on it with a force of 100 n. what is the spring constant
