Humid air breaks down (its molecules become ionized) in an electric field of 4.99 x 10^6 n/c. in that field, what is the magnitude of the electrostatic force on (a) an electron and (b) an ion with a single electron missing? (a) number units (b) number units

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is
