Answer:
Power dissipated in resistor 532 ohm is 0.503 watt
Explanation:
We have given in first case resistance 
Power dissipated in this resistance is 
Power dissipated in the resistor is equal to 
We have to find the power dissipated in the resistor is 1.30 watt
From the relation we can say that 


So power dissipated in resistor 532 ohm is 0.503 watt
Answer:

Explanation:
Given


Required
Determine the distance at which the lighting struck
First, we need to determine the speed at which the lighting struck because the peed of sound varies with temperature.
At about 28C, the speed of sound is 346m/s
So, we have the following:


Distance is calculated as thus:



Divide by 1000 to get distance equivalent in kilometers
