Answer:
When the magnetic field is tilted so it is no longer perpendicular to the page.
When the magnetic field gets stronger.
When the size of the loop decreases.
Explanation:
According to the Faraday-Lenz law, the change of the magnetic flux over time causes an induced current, this flux is given by:
Therefore, there will be a variable magnetic flux, when the magnitude of the magnetic field (B) changes over time, when the area of the loop (S) changes over time and / or when the angle (
) between the field and the surface vector changes over time.
X=.5(a)t^2 can be used: 2.5m=.5(g)(1), g=5m/s^2.
Answer:
c
Explanation:
................................................
If energy input remains
constant and voltage remains the same in a circuit, but the current decreases,
the power has increased. It is presented in the equation P = VI where P is
power, V is voltage and I is current.
Momentum is transferred from the first object to the second object. In this case, if a gun exerts a force on a bullet when firing it forward then the bullet will exert an equal force in the opposite direction on the gun causing it to move backwards or recoil.
