Answer:
here the coil must be oriented in such a way that its plane is perpendicular to the magnetic field
Explanation:
As we know by Faraday's law of electromagnetic induction
Rate of change in magnetic flux will induce EMF in the coil
so here we will have
here we know that
now if the magnetic flux will change with time then it will induce EMF in the coil
so here induced EMF will be zero in the coil if the flux linked with the coil will remain constant
so here the coil must be oriented in such a way that its plane is perpendicular to the magnetic field
In such a way when coil will rotate then the flux linked with the coil will remains constant and there will be no induced EMF in it
Answer:
0.52rad/s^2
Explanation:
To find the angular acceleration you use the following formula:
(1)
w: final angular velocity
wo: initial angular velocity
θ: revolutions
α: angular acceleration
you replace the values of the parameters in (1) and calculate α:
you use that θ=22 rev = 22(2π) = 44π
hence, the angular acceñeration is 0.52rad/s^2
When two things in contact with each other transfer heat - Conduction
When a liquid or has carries heat- Convection
When waves transfer heat- Radiation
Answer:
Reaction force
Explanation:
A ball is thrown against a wall: The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off
