Answer:
The inverse operation of squaring a number is finding the square root of a number. The square root cancels out the square. For example, 3² = 9. To cancel out the square, we have to take the square root. So, √9 = 3. Hope this helped.Step-by-step explanation:
Answer:
94.05 mV
Step-by-step explanation:
N = Number of turns = 149
r = Radius of coil = 2.45 cm = 0.0245 m
t = Time = 0.141 s
Initial magnetic field = 50.9 mT
Final magnetic field = 98.1 mT
A = Area = πr² = π×0.0245²

∴ Magnitude of the average EMF, that is induced in the coil during this time interval is 94.05 mV
Round both of the first to one significant figure 30/10 is 3
60x20= 120
