1.	a swimmer wades through water at a speed of 0.18 ms. the force of the water acting aganist his movement is 120N . cal. the power developed by the swimmer ?
Answer» <P>Answer: Explanation: We have to FIND out the power which is developed by the swimmer. To obtain power (P), substitute 110 N for F and 0.22 m/s for V in the equation P = Fv, P = Fv = (110 N) (0.22 m/s) = 24.2 N. m/s = (24.2 N. m/s) (1 W/1 N.m/s) = 24.2 W …… (2) Rounding off to two significant FIGURE, the power which is developed by the swimmer will be 24 W

<P>Answer:

Explanation:

We have to FIND out the power which is developed by the swimmer.

To obtain power (P), substitute 110 N for F and 0.22 m/s for V in the equation P = Fv,

P = Fv

= (110 N) (0.22 m/s)

= 24.2 N. m/s

= (24.2 N. m/s) (1 W/1 N.m/s)

= 24.2 W …… (2)

Rounding off to two significant FIGURE, the power which is developed by the swimmer will be 24 W
