Answer:
a)
b)
Explanation:
a) Let's use the constant velocity equation:
b) Here we need to use Lorentz factor because the speed of the muon is relativistic. Hence the time in the rest frame is the product of the Lorentz factor times the time in the inertial frame.
v is the speed of muon (0.9c)
Therefore the time in the rest frame will be:
No we use the value of Δt calculated in a)
I hope it helps you!
The correct is 72 watt
We know that formula of power is
so putting the value of Voltage and Resistance in Formula of power so we get
What is Power?
Electric power is the rate at which an electric circuit transfers electrical energy per unit time.
Typically, electricity is generated by generators, but it can also be supplied by sources such as electric batteries. The electric power industry typically distributes it via an electric power grid to businesses and homes (as domestic mains electricity).
Transmission lines allow electric power to be delivered over long distances and used for high-efficiency applications such as motion, light, or heat. Electric charges are converted to other forms of energy when they pass through an electric potential difference (voltage).
