Answer:
(A) 654.545 Kw
(B)
Explanation:
We have given resistance of the toaster
Resistance of nichrome heating element
Both the resistances are connected in series so same current will flow through the circuit
Potential difference across the toaster V = 120 volt
So current
(a) Power dissipated in toaster
(B) Power dissipated in heating element
B)<span>Readily accept electron flow.</span>
It will be unaffected by the magnet because it has no magnetic field. If you were to maybe have electricity going through it is the only way it would have anything to do with the magnet.

Answer:
7.5Watts
Explanation:
Given parameters:
Force of lift = 25N
Height = 3.6m
Time = 12s
Unknown:
Power output = ?
Solution:
Power is the rate at which work is done ;
Power =
Power = = 7.5Watts
