A certain rain cloud at an altitude of 2.07 km contains 3.20 ✕ 107 kg of water vapor. How long would it take for a 2.55-kW pump to raise the amount of water from Earth's surface to the cloud's position?
A certain rain cloud at an altitude of 1.70 km contains 3.20 x 107 kg of water vapor. How long would it take for a 2.63-kW pump to raise the amount of water from Earth's surface to the cloud's position?
7. (Work and Energy) Atmospheric conditions near the Great Lakes are such that a cloud at an altitude of 1.50 km contains 3.20 ✕ 107 kg of water vapor. How long (in years) would it take for a 2.63 kW pump to raise this amount of water (at a constant speed) from Earth's surface to the altitude of the cloud?
Please help me with both questions. I don't have any more
questions left and its really urgent. Please!

One cubic centimeter of a typical cumulus cloud contains 360 water drops, which have a typical radius of 10 μm. (a) How many cubic meters of water are in a cylindrical cumulus cloud of height 3.2 km and radius 1.1 km? Answer in m^3. (b) How many 1-liter pop bottles would that water fill? (c) Water has a density of 1000 kg/m3. How much mass does the water in the cloud have? Answer in kg.

[Extra point]A typical comet contains 1013 kg of water ice. How many comets would be needed to account for the 2 × 1021 kg of water presently found on our planet? If this amount of water accumulated over a period of 0.5 billion years, how frequently must Earth have been struck by comets during that time? Chapter 5 (10) Because of tidal forces, the Moon is in a synchronous orbit around Earth True False (11) Explain how the Moon produces...
A well-insulated rigid tank contains 5.80 kg of a saturated liquid-vapor mixture of water at 225 kPa. Initially, one-quarter of the mass in the liquid phase. An electric resistor placed in the tank is connected to 240-V source, and a current of 6 A flows through the resistor when the switch is turned on. Determine how long it will take to vaporize all the liquid in the tank in minute.
