Answer:
e= 0.440 mV(millivolt)
Explanation:
Given Magnetic field B= 0.50T
Δt= 1.6sec
⇒
e= 0.440 mV(millivolt)
1/R=1/3+1/6
1/R=2/6+1/6=3/6
R=6/3=2ohms
Total R=2ohms
Answer:
2.62 A
Explanation:
B = 2 T, Diameter = 2.5 cm , radius, r = 0.0125 m, t = 0.45 s, r = 0.01 ohm
Induced emf, e = rate of change of magnetic flux
e = A x dB / dt = 3.14 x (0.0125)^2 x 2 / 0.45
e = 0.026 V
induced current, i = e / R = 0.026 / 0.01 = 2.62 A
Explanation:
Newton’s third law of motion states that every action has an equal and opposite reaction. This indicates that forces always act in pairs. Reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don’t cancel each other out.
