Question

the lungs perfrorm 2.4 J of work during each expansion how many times per minute do they expand if their power is 2W​

Answer 1

Explanation:

Given,

Work done by lungs is 2.4 J

One minute is equal to 60 seconds

Work = power * time

Work = 2 * 60 = 120j

Expansions = 120/2.4 = 50

The lungs perform 2.4J of work during each expansion. How many times per minute do they expand if their power is 2W?

Given : P = 2W,

Work during each expansion = 2.4J,

time = 1 min = 60 sec.

=) Work = Power * time

= 2 * 60 = 120J

No of expansions per minute = 120/2.4

= 50.
