The statement ‘According to Faraday's law, voltage cannot be changed by changing the magnetic field strength’ is false. No matter how the change is created, voltage will always be produced and it could be the magnetic field strength, moving magnet toward or away from the coil etc. This is because the voltage is directly proportional to the number of turns and the magnetic flux.

When heat is transferred to a substance explain why the temperature goes up
b. 9.8 meters per minute
c. 8.9 meters per minute squared
d. 9.8 meters per second squared
Answer:
9.8 meters per second squared
Explanation:
I calculated it several times and got the same answer, 40.38m/s, but the textbook says it's 28.6m/s.
A scientist would use a unit of length appropriate for the magnitude of what he or she is measuring. In this case, since rock is built up very slowly, they would probably use millimetres or centimetres. In some cases they may use meters.
There you go.
