Question Use the work-energy theorem to calculate the potential energy, kinetic energy, and velocity at different points on the diagram below. The mass of the
ball is 5 kg.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

so easy. just google the electromagnetic waves and it’ll pop up.

the maxium height is 34m/s

because if the tool that you are using is not balanced it there would be false mass.
