v = x/t
v = average velocity, x = displacement, t = elapsed time
Given values:
x = 6km south, t = 60min
Plug in and solve for v:
v = 6/60
v = 0.1km/min south
It is true because if you do the four by four graph you will see what happens and i just did it right now
Answer: C
Explanation:
The flux due to the loop always opposes the change in the flux due to the external magnetic field. This occurs as a result of the current that is induced in a coil (due to a magnetic flux change through the coil) which will always be in such that it opposes the change that caused it. ... Any induced current in a coil will result in a magnetic flux that is opposite to the original changing flux. This was what Faraday was explaining in the law of Induction
Answer: B 6.2 Hz
Explanation: Equation for waves v = λf.
Frequency = speed / wavelength f = v/λ
f = 74 m/s / 12 m = 6.166... Hz
