Answer true, false, or Cannot tell to teach of the five statements below.
A) A 2 kg ball and a 3 kg ball are dropped from a tower. The net forces on each other are the same.
B) An astronaut stands on a bathroom scale on the surface of the moon; the scale reads the astronaut's true weight.
C) A box with a 100 kg passenger is catapulted straight into the air. The passenger's true weight is zero once the box is airborne.
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 ascending and speeding up.
E) The mass of an object depends on its location.
No equations, just theory.
The Attempt at a Solution
A) False, net force in free fall = weight of an object, and a 2 kg ball and a 3 kg ball have different weights.
B) False, gravity is different on the moon and the bathroom scale would read differently.
C) False, the passenger's apparent weight would be zero once box was airborne, but their true weight would remain the same.
D) Unsure about this one, but I believe it would be "Cannot tell", because I'm unsure if "speeding up" = acceleration.
E) False. Mass is constant.
I have already tried entering these answers (False, false, false, cannot tell, false) and it is not correct. Does anyone have any advice or comments about how my reasoning is incorrect?
