Answer:
5.77 Volt
Explanation:
N = 1000, Diameter = 42 cm = 0.42 m, t = 12 ms = 12 x 10^-3 s
Change in magnetic field, B = 5 x 10^-5 T
The peak value of emf is given by
e = N x dФ / dt
e = N x A x dB/dt
e = (1000 x 3.14 x 0.21 x 0.21 x 5 x 10^-5) / (1.2 x 10^-3)
e = 5.77 Volt

Answer:
what was the answer? Was it 0.98?
You will need to turn this into scientific notation, so:
1.176 × 10^1 cm^2
To two significant figures means to two digits so since 7 is greater than 5, you will need to round up.
Final answer is:
1.2×10^1 cm^2
