Answer:
The fraction of its energy that it radiates every second is .
Explanation:
Suppose Electromagnetic radiation is emitted by accelerating charges. The rate at which energy is emitted from an accelerating charge that has charge q and acceleration a is given by
Given that,
Kinetic energy = 6.2 MeV
Radius = 0.500 m
We need to calculate the acceleration
Using formula of acceleration
Put the value into the formula
Put the value into the formula
We need to calculate the rate at which it emits energy because of its acceleration is
Put the value into the formula
The energy in ev/s
We need to calculate the fraction of its energy that it radiates every second
Hence, The fraction of its energy that it radiates every second is .
Answer:
E = 3600 J
Explanation:
Given that,
Voltage, V = 115 V
Power of electric bulb, P = 60 W
We need to find the electric energy used in 1 minute. The electric energy use is given by :
Hence, the electrical energy is 3600 J.
