Answer:
3.3 lambda
Explanation:
Velocity = frequency * wave length
Wave length = velocity / frequency
Wave length = 330/100
Wave length = 3.3 lambda
It will take the ball 4 seconds to reach the ground because (120/2= 60/2=0= 2+2=4)
Answer:
D. Opposes the applied flux through the conductor.
Explanation:
- <em><u>According to the Lenz's law, the direction of induced e.m.f is such that it generates a current which in turn produces a magnetic field that would oppose the change causing it.</u></em>
- In other words, the direction of any magnetic induction effect is such that it opposes the cause of the effect.
- Therefore; an induced magnetic field in a conductor, opposes the applied flux through the conductor.
It changes due to Earth's axis spinning.
