If gravity is always pulling things down how does helium rise?
In a vacuum, a balloon with helium (for example) would also fall down. The point is that gravity pulls on the surrounding air with more force, because it is heavier; this pushes the balloon up. The situation is similar to a boat floating in water. The water displaces the boat - pushing it up precisely because of gravity.
What is the answer for the question rise and fall of water caused by friction of wind on water surface?
wave
Does gravity force a hellium balloon to rise?
No, not directly ... it needs gravity to be present, but gravity alone won't do it. There's plenty of gravity on the moon, but a helium balloon won't rise there. A helium balloon floats in air, for exactly the same reason that a block of wood floats in water. Look up "Archimedes' Principle" and read about it.
What vehicle can overcome earth's gravity because it expels a gas with a force equal to the pull of gravity?
That sounds like a "hovercraft", which doesn't rise or fall, but just exactly hangs there.If the vehicle expels a gas with a force GREATER than the pull of gravity ... like a rocket for example ...then it can actually rise.
Why do air bubbles in water rise?
Bubbles are comprised of gases, which have a lesser density than water. Since they are less dense, they get pushed up to the surface, and they rise, lighter than the liquid around them.
The rise and fall in sea level caused by gravity is called?
tide
What is the rise and fall of water called?
Tide.
What is the rise and the fall of ocean water called?
The tide
Why do earth's oceans rise and fall in rise?
Because of gravity.
What does Sir Isaac Newton have to do with tides?
he proved that there was a force called gravity. the moon's gravity causes water to rise.
The daily rise and fall of earths water on its coastlins are called?
Tides
The rise and fall of ocean water are called?
Tides are the rise and fall of ocean water. They are the combined effects of the gravitational forces exerted by the sun and moon on the rotation of the Earth.
What is the name of the sudden rise and fall of Lake Michigan?
The rise and fall of lake michigan's water, and any other lake or ocean is called a wake.
Why does a paper fall differently on the moon than on earth?
because of gravity. the paper will not actually fall onto the moon but rise up. earth has 10.0n of gravity and the moon has much less, so it wont fall but rise.
What is the alternate rise and fall in the level of sea water?
The rise and fall is the tides.
What is the cyclical rise of fall of ocean water?
The cyclical rise or fall of the waters of the ocean is called tide. The tides are caused by the attraction of gravities of the moon, sun, and Earth
The periodic daily rise and fall of ocean water?
The cyclical rise or fall of the waters of the ocean is called tide. The tides are caused by the attraction of gravities of the moon, sun, and Earth
