Answer:
Please find the answer in the explanation.
Explanation:
When you try to move the magnet back and forth between the two coils, the motion of the magnet will be oscillatory and this action will cause current and EMF to induce
According to law of Faraday, current or EMF will be induced when a magnet is moved in the presence of coils
If the magnet continues to move back and forth between the two coils, what might be causing this will be the presence of the induced electromagnetic force between the two coils.
The frictional force is given by
where m is the mass of the puck,
and
is the dynamic coefficient of friction.
The work done by this force to stop the puck is
where
is the total displacement of the puck.
The initial kinetic energy of the puck is
with v being the puck initial velocity. The puck comes to rest after 12 m, this means it loses all its kinetic energy, and for the principle of conservation of energy this loss of energy is equal to the work done by the frictional force. So we can write
and from this we can find the inizial velocity of the puck:
Answer:
300 Btu per hour
Explanation:
given data
area = 100-square foot
thick = 12 inch
R value at 12 = 1.89
R value at 4 = 14.8
inside temperature = 65 degrees F
outside temperature = 15 degrees F
to find out
How many Btu per hour
solution
we get here How many Btu per hour that is express as
Btu per hour = ............1
put here value we get
Btu per hour =
Btu per hour = 299.580
so Btu per hour is 300 Btu per hour
