Explanation:
Newton's second law:
∑F = ma
277 N − 245 N = (25 kg) a
a = 1.28 m/s²
Answer:
213.18 volt
Explanation:
N = 500, A = 0.02 m^2, B = 0.30 T, f = 960 rpm = 960 / 60 = 16 rps
The maximum value of induced emf is given by
e0 = N x B x A x ω
e0 = N x B x A x 2 x π x f
e0 = 500 x 0.3 x 0.02 x 2 x 3.14 x 16
e0 = 301.44 Volt
The rms value of induced emf is given by
e rms = 213.18 volt
The figure shown above is series combination as the two resistors (bulb) are there which are then connected to the battery
so i conclude from the above options given the option is B
