While discussing with another group regarding the amount of charge calculated to be on a piece of tape, you see they calculated a value of 4.5 x 10^-24 C. Why do you know that there must be a mistake in either their measurements or calculations? a) We are not working with distances small enough to get a charge that small. b) You cannot have less than the charge of a single electron on the piece of tape.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
