A certain rain cloud at an altitude of 1.90 km contains 3.20 107 kg of water vapor How long would it take for a 2.89-kW pump to raise the amount of water from Earth's surface to the cloud's position?

The gravitational potential energy of that water relative to the ground is [ M G H ] =
(3.2 x 107) x (9.8) x (1,900) = 5.9584 x 1011 Joules
Power = (energy)/(time)
Time = (energy)/(power) = 5.9584 x 1011 joules/2,890 watts = 206.2 million seconds = 6.53 years

At what altitude above the earth surface the value of 'g' reduces to half of its value at the surface?
at about 9km above the surface of the sea.
What units would be used to measure the surface temperature of a plane?
Surface temperature is the temperature of a body at a particular location. Factors that affects this temperature are altitude, and environmental temperature. The surface temperature declines or goes up as the plane changes altitude.
Why does a helicopter lose altitude when flying over a water surface?
A helicopter needs a solid surface to fly over.
Height of an object above earths surface?
Altitude. Height. Depends on what you are measuring.
Does the mass of an object change with location or altitude above the Earth's surface?
No it does not. Its weight, however, does.
What is the measure of height above earth surface is called?
Altitude
How do you spell altitude?
That is the correct spelling of "altitude" (height above the surface).
why is it colder at altitude?
Because when the sun's rays hit the Earth's surface, they make it hot. As we, by whatever means, move upwards, the heat of the Earth's surface will decrease because we move away from it. The higher the altitude, the lower the temperature, up to a certain height, and from there it stabilizes. And this within the terrestrial domain
What the height above the surface of the Earth?
altitude
What is sailing by the stars?
Astral navigation. By using a sextant (instrument used to measure the altitude of a celestial object) a clock and logarithms you can work out your position on the earth's surface hence 'sailing by the stars'
Is the altitude greater at the top of a mountain?
A mountain top is higher (greater) in altitude. That is the definition of altitude : height above a surface, or above sea level.
What is the defference between latitude and altitude?
latitude is how north or south a place is from the equator. altitude is how high you are from earth's surface
At what altitude above the earth surface the value of 'g' reduces to half of its value at the surface?
at about 9km above the surface of the sea.
A measure of height above earth's surface is called?
altitude
What is absolute altitude?
The vertical distance of the aircraft above the surface.
When does altitude occur?
Altitude is a measure of the height of something above sea level, or above some point on Earth's surface.
Is it possible to place a satellite in geosynchronous orbit at a much lower altitude?
No. To remain in orbit it needs to have a certain speed, and that speed will only match the surface speed of the earth on a certain height. To go lower it'd have to go slower, and then it'd fall.
