What term is applied to the situation in which energy has been transferred from faster particles to slower ones and as a result
Alborosie

Answer:

Conduction

Explanation:

Conduction refers to the transfer of energy through the movement of particles that are in contact with each other. It could be heat conduction, electrical conduction or sound conduction. Heat conduction (or thermal conduction) is the transfer of energy from a warmer substance to a colder one through direct contact, for example, someone touching the handle of a hot metal skillet.

Electrical conduction is the transfer of electrically charged particles through a medium, for example, electricity traveling through the power lines in a house.

Sound conduction (or acoustic conduction) is the transfer of sound waves through a medium, for example, vibrations from loud music passing through a wall.

A crate with a mass of m = 450 kg rests on the horizontal deck of a ship. The coefficient of static friction between the crate a
Zielflug [23.3K]

Answer:F_{v} =\mu_{k} mg

Magnitude of the force is 2601.9 N

Explanation:

m = 450 kg

coefficient of static friction μs = 0.73

coefficient of kinetic friction is μk = 0.59

The force required to  start crate moving is F_{s} =\mu_{s} mg.

but once crate starts moving the force of friction is reduced  F_{v} =\mu_{k} mg.

Hence  to keep crate moving at constant velocity we have to reduce the  force pushing crate ie F_{v} =\mu_{k} mg.

Then the above pushing force will equal the frictional force due to kinetic friction and constant velocity is possible as  forces are balanced.

Magnitude of the force

F_{v} =\mu_{k} mg\\F_{v} =0.59 \times 450 \times 9.8\\F_{v} =2601.9  N
