What are the useful and harmful effect of friction?
Useful effect of friction - automotive clutch , friction material on adjacent plates help give grip the other plate connected to drive shaft , hence allowing the friction to slowly bring the drive shaft up to speed , otherwise the motor would just stall. Or to give useful grip to tyres on the road. Harmful effect of friction - makes bearing harder to turn since friction holds on to surface between the bearing and the bearings outer surface
What plasma display uses between two plates?
layers of film or glass plates?
If the acceleration of a charged particle between plates in a plate capacitor is a at halfway between the plates why will the particle experience the same acceleration when its 1 quarter of the way?
Because the field between plates in a capacitor is homogenous. It has the same strength in every point of the field.
Why is there no friction when two glass pieces are kept together?
There is friction, but comparatively little unless the glass is very clean. Because the glass is not touching over the majority of its surface. Instead trapped air is between the two plates. This massively reduces the coefficient of effective friction. Normally, if glass is clean so that the surfaces can touch, they will "stick together" as they are so flat and friction is so high - ask anyone working with glazing glass - they try never to let two panes touch except at an edge.
What experiment did j.j Thomson do?
He sent a cathode ray between electrically charged metal plates.
What causes plates to stop moving temporarily?
Friction causes plates to stop moving temporarily. The motion of the magma under the plates will cause the plates to move again.
What causes a major earthquake to occur where plates meet?
The friction between the plates. When the friction is resolved, an earthquake occurs.
What direction is the Philippine Mobile belt moving?
It's staying still. A mobile belt is the tectonic boundary between plates.
The maximum torque transmitted by a single friction clutch plate depends on what factors?
The outer diameter of the friction lining, the inner diameter of the friction lining, the coefficient of friction between the plates, the number of friction plates ( in this case 2), the surface pressure acting on the friction plates
What direction does the ground surface move during an earthquake?
The Earth moves in response to tectonic forces which move the plates around, causing friction and the release of friction between adjoining plates, the creation of mountains, and the subduction and creation of crust. All of these movements can result in earthquakes.
DO all the plates moving in the same direction?
Nope! They move in different directions which is why there are earthquakes.
What is the general cause of an earthquake?
The Earth's land masses (tectonic plates) moving against each other. Friction.
What is the relationship between volcanoes and Earth's moving plates?
When the plates collide they form volcanoes and earthquakes.
Do tectonic plates make friction?
Friction itself is a naturally occurring force but yes, tectonic plates do encounter friction.
The places between plates moving together are called?
faults.
What is the boundary between two moving plates called?
h
What is the difference between convergent boundary and convergent plate boundary?
Convergent means where plates are moving together. Divergent means where plates are moving apart.
