Which are the sports in which friction is not useful?
There is not a sport in which friction is not useful. In hockey, for example, there seems to be no need for friction. However, in order to get moving or stand at all, the players rely of the friction between their skates and the ice. The friction between their skates and the ice also creates a thin layer of water while they skate, allowing them to glide over the ice. even chess relies on friction so the pieces do not move off the board.
Can you give a conclusion about friction?
friction is the force resisting the relative motion of solid surfaces,fluid layer,or meterial elements in contact
Can a liquid experience friction?
As liquid flows on an inclined surface there will be frictional force between the bottom most layer and the surface of inclined plane. More over there will be a friction between the successive layer of the liquid. This is termed as viscous force.
How does lubicus help to reduce friction?
Lubricants reduce friction by various means. Here are some:They form a layer between surfaces that are moving with respect to each other that keeps those surface from contacting each other. The lubricant keeps the surfaces apart.The lubricant washes away particles that might cause friction between the surfaces. It acts as as cleanser.Some lubricants harden the surfaces of the parts they are lubricating to make them less subject to wear.
What is it called when a layer of warm air is above and traps a layer of cold air below?
Inversion
What layer of Earth can you find convection currents?
Convection currents occur in the mantle of the earth. They can affect the crust and the life above it, though.
What is the layer that has convection currents that move the plates?
This layer is the mantle.
The layer in which convection currents move?
Convection currents move in the Mantle.
What are convection currents and in which layer do they occur?
no
What layer of convection currents located in?
face
Which layer is most affected by conduction?
the layer that has convection currents is the mantle
The layer of rock that has convection currents flowing?
The asthenosphere.

Why does the earth's water layer make good insulation?
it has currents
What is the speed of wind at different heights?
Wind tends to reach a maximum about 3/4 of the way up in the atmosphere above 20-25,000 feet. It is a minimum at the surface, where friction slows it down. Above the boundary layer, at a couple thousand feet, is generally where air is no longer slowed by friction from the surface.
What is the layer directly above the troposphere?
The layer above the troposphere is the stratosphere.
Does the depth of a river affect the speed of the flow?
Yes because in shallow watewr the water and the bottom of the river rub and create friction in deep water the water the water is moving on top of another layer of water so less friction is created making it faster.
