0.400. The system starts from rest.
What is the speed of the ball of mass m2 5.00 kg
when it has fallen a distance h = 1.50 m?
Ans. 3.74 m/s

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

that would be because of both gravity and friction. so     c

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
