Q. A sculptor has asked you to help electroplate gold onto a brass statue. You know that the charge carriers in the ionic solution are gold ions (Au+1), and you have calculated that you must deposit 0.871 g of gold to reach the necessary thickness. How much current, in mA, do you need to plate the statue in 4.08 hours? Assume that the atomic weight of gold is 197 amu.

Q. A small plane climbs with a constant velocity of 240 m/s at an angle of 24° with respect to the horizontal. Which statement is true concerning the magnitude of the net force on the plane?
