What is the difference in neil armstrong’s weight on the moon and on earth? neils mass is 160kg including his spacesuit and backpack. the moon’s gravitational pull is only 17% of the earths gravitational pull. assume the earth’s gravitational pull is 10n/kg (if you can show working out.)

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
