Answer:
(B) 0.06W
Explanation:
power absorbed by the resistor is given by
Where V = voltage
R= resistance
I = current through the circuit
we have given V =12 Volt and resistance =2.4 K![\Omega](https://tex.z-dn.net/?f=%5COmega)
current ![I=\frac{V}{R}=\frac{12}{2.4\times 1000}=5\times 10^{-3}A=5mA](https://tex.z-dn.net/?f=I%3D%5Cfrac%7BV%7D%7BR%7D%3D%5Cfrac%7B12%7D%7B2.4%5Ctimes%201000%7D%3D5%5Ctimes%2010%5E%7B-3%7DA%3D5mA)
power using voltage and resistance equation
=0.06W
using current equation
= 0.06W
Speed=
![33m {s}^{ -1}](https://tex.z-dn.net/?f=33m%20%7Bs%7D%5E%7B%20-1%7D%20)
Distance=
![163m](https://tex.z-dn.net/?f=163m)
speed= distance/time
So,
<u>Time</u><u>=</u><u> </u><u>distance</u><u>/</u><u>speed</u>
Time= 163/33
