Answer 1

HI MY FRIENDS,

HERE IS YOUR ANSWER ,

40W IS USED FOR 8 HOURS .

AND

YOUR QUESTION IS TO FIND HOW MUCH UNIT OF ENERGY USED IN A DAY

AS WE SIMPLY KNOW THAT A DAY IS CONSISTS OF 24 HOURS .

AND WHEN 24/8 (24÷8) THEN IT CAMES 3. .

NOW

WE HAVE TO MULTIPLY 3 FROM 40 THEN

= 120.

IT MEANS THAT 120W ARE USED IN ONE DAY.
