A rocket blasts off from the Earth on its way to the moon. As the rocket travels, it loses mass due to burning fuel and ejecting stages of the rocket. When the mass of the rocket has been reduced to one-half of its original mass it has traveled a distance equal to the radius of the Earth away from the surface of the Earth, where it took off. At this point, how does the gravitational force between the rocket and the Earth compare to the gravitational force at lift-off?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

On a day when the barometer reads 75.23 cm, a reaction vessel holds 250 ml of ideal gas at 20 celsius. an oil manometer ( ρ= 810 kg/m^3) reads the pressure in the vessel to be 41 cm of oil and below atmospheric pressure. what volume will the gas occupy under s. t.p.?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
