Answer:
Efficiency = 5%
Explanation:
Given that,
Supplies energy to the bulb = 100 J
Transferred energy by the bulb = 5 J
We need to find the efficiency of the bulb. It can be given by "

So, the efficiency of the bulb is 5%.
Answer:
0.005 V
Explanation:
We are given that
Initial circumference of circular loop=C=165 cm
Rate of circumference,
Magnetic field,B=0.5 T
We have to find the induced emf at time t=9 s
We know that induced amf,E=
Area of circular coil,A=

Circumference of circular coil,C=



Radius of coil at time t=9 s


E=
Magnitude of induced emf=0.005 V
Do you mean period of time, period as in English spelling, or a period that concerns the medical field?
