Explanation:
We know that,
frequency (f) = 1 / t (sec) = 8/60 = 0.13 Hz
V ( wave speed) = 0.13 * 120 = 16 m/sec
Answer: counterclockwise
Explanation:
As the area of the loop decreases steadily, the flux through the loop also decreases. By Lenz’s law, any induced current will tend to oppose the decrease. Using Flemming right hand rule (Fleming's right-hand rule which shows the direction of induced current) we know that magnetic field inside the loop due to a counterclockwise current comes out of the plane. Therefore a counterclockwise current will create a stronger magnetic field inside
the loop, tending to increase the flux.
When a wire loop is moved in the direction of the current or a wire loop is being pulled through a uniform magnetic field there would be no induced current ( current loop is said to be zero)
The answer is 100 kg because the gravitational attraction is greater in objects that have more mass ;)
Your answer would be D. It becomes <em>gravitational potential </em>because the person is moving up a hill, kinetic energy because the bike is moving, and heat because of friction between the wheels and the bike.
