1. The problem statement, all variables and given/known data
Answer True, False, or Cannot tell to each of the five statements below.
E.g., if the answer to the first statement is `true' and to the rest, `cannot tell', enter TCCCC.
A)You pour 100 g of salt onto a spring scale in an elevator accelerating upward. The scale reads a value greater than 100 g.
B)A 2 kg and a 3 kg ball are dropped from a tower. The net forces on each are the same.
C)Mass and weight describe the same thing, although in different units.
D)You are standing on a jet-powered platform that can move straight up or down. Your apparent weight is greater than your true weight if the platform is descending and speeding up.
E)An astronaut stands on a bathroom scale on the surface of Jupiter; the scale does not read his true weight.
2. Relevant equations
3. The attempt at a solution
I have tried attempted many solutions (13 out of 15 tries used up). I am fairly sure that B), C), and D) are false. Quick help would be appreciated, time is running short.
