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.
Answer:
by reducing friction.....
That the climate changes during the day and night high to low
When air is blown across the top of an open <span>water bottle, air molecules in the bottle vibrate at a particular frequency and sound is produced in a process called "refraction".

Answer:
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
.
but once crate starts moving the force of friction is reduced
.
Hence to keep crate moving at constant velocity we have to reduce the force pushing crate ie
.
Then the above pushing force will equal the frictional force due to kinetic friction and constant velocity is possible as forces are balanced.
