A small glass ball is given a charge of +2.0 µC. It is placed 12 cm from a small charged rubber ball with a charge of –3.5 µC. What is the electric force between the two balls?

0.93xc=0.93x3x10^8m/s

2.54cm is 1 inch

360seconds i 1 hr

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
