Question

physics is a really beautiful and entangled subject!! ​

Answer 1

Explanation:

I do agree my friend,

Answer 2

Answer:

Given:

Voltage = 240 V

Power = 1.5 KW

The AC is switched on for 8 hours everyday.

To find:

Total electrical energy consumed in 30 days.

Concept:

Power of any appliance is the rate of doing work .

Mathematically, we can say that

$power = \dfrac{work}{time}$

$= > work \: = power \times time$

Here work done refers to the total energy consumed by the AC.

Calculation :

Total energy consumed in a day

$= 1.5 \times 8$

$= 12 \: kilowatts \: hr$

Hence, total energy consumed in a month

$= 12 \times 30$

$= 360 \: kilowatt \: hr$

So final answer is

$\boxed{ \red{ total \: energy = 360 \: kilowatt \: hr}}$
