The greenhouse effect was discovered by Joseph Fourier in 1824
It's a runway guard light. It's to advise aeroplanes that they are approaching the runway and should stop until advised to the contrary.
The crankshaft has counterweights which are placed in such a way as to provide momentum when the the power stroke of any piston is absent. This drives the crankshaft to spin until the next power stroke of a piston drives it further.
Since Newton is the unit for Force. And as we know "Force = Mass * Acceleration" Newton = Kg * 9.81 Therefore , Kg = Newton / 9.81 Hence, Mass = 22000/9.81 = 2200 (approx)
there is gravity on the moon you prick its just less
Probably neither. Cars are not air tight. Any air trapped in the car to begin with would leak out through the vents and around the doors and windows.
Gravitational attraction is caused by the mass of the earth. As you go down in the earth, the amount of mass of earth still between you and the centre of earth decreases. Thus as this effective mass decreases, the gravitational attraction decreases.
