To recharge a 3.7V Lithium-ion battery, a battery charger must move 1320 mAxh of charge from the negative terminal to the positive terminal. How much work is done by the charger? Hint: This is not a capacitor! Convert mAxh to C first. (I don't know how to do this).
An object of mass "m" is thrown up an inclined plane of angle "theta" with an initial velocity "v knot". If the motion is resisted by retarding force Fr=-kv (where k is a force coefficient and v the velocity of the object.)
Find the direction of the net electrical force electrons will exert on the proton. Enter your answer as an angle measured relative to the line connecting the proton and the right electron with counterclockwise being positive.
A 0.7 kg block of ice is sliding by you on a very slippery floor at 3.5m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with ice block for 0.003 seconds.
