What kind of objects float above water?
Any item that is lighter than the water will float on the surface of the water.
Which surface has the lowest friction?
The surface that has the lowest friction is a wet surface, or a surface that has been oiled with light oil, or the air cushion underneath a hovercraft. Then there is the train that runs on magnetic rails, hovering above the rails without physically touching.
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.
Why does salt water affect the way objects float?
salt water is different from tap water. when salt is added to water it converts the tap water to salt water. This increases the density of the water, and allows more objects to float above it. remember, when objects are mixed like that, the greater the density, the further it is from the surface.
How does air above a cooled surface move?
Air above a cold or cooled surface contracts and falls.
What kind of objects float above water?
Any item that is lighter than the water will float on the surface of the water.
Why is the gravitational potential energy of an objects 1 meter above the moons surface less than its potential energy 1 meter above Earths surface?
because the value of gravitational force of earth is greater than that of moon.
Which do hyphae, which extend above the surface of wherever a fungus is living, typically support?
reproductive structure
Which instrument is used to observe objects on the surface from a submarine?
A periscope is used to observe the surface from a submarine
The support disks hold cable off the pavement surface what is the minimum cable height above the pavement?
2 inches
How does air above a cold surface?
how does air above cold surface move

Epicenter?
the location on the surface directly above the focus
Where does ionosphere begin above Earth's surface?
it begins at 559327 feet above aerths surface
What is epiphytes?
Epiphytes are plants that grow above the ground using other plants or objects as support or platforms to grow from. They are not parasite plants. There are thousands of these plants all over the world.
