Aproton is moved from a position where the electric potential is 125 v to a position where the electric potential is 275 v. the magnitude of the charge on a proton is 1.602 × 10-19 c. what is the change in electric potential energy of the proton?
2.0 × 10-17 j
2.4 × 10-17 j
4.4 × 10-17 j
6.4 × 10-17 j

We determine the electric potential energy of the proton by multiplying the net electric potential to the charge of the proton. The net electric potential is the difference of the final state to the that of the initial state. So, it would be 275 - 125 = 150 V.

electric potential energy = 150 (1.602 × 10-19) = 2.4x10^-17 J

Texture and composition are different because they are not the same aspect. texture has to do with feel and so on, where as composition is the chemical makeup which you cant touch like you can texture.

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.
