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.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

i think the answer is tomato juice? not entirely sure though

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
