Answer 1

Answer:

16 watts

Explanation:

1 newton = (1kg*m/s^2)

1 joule = 1 newton*metre

unit of power = watt = (joule/sec)

= (newton*metre/sec)

= (kg*m*m/sec^3)

= (kg*m^2/sec^3)

= (20*10^2/5^3)

= (2000/125)

= 16 watts

Answer 2

Answer:

= 16 watts

Explanation:

unit of power = watt = (joule/sec)

= (newton*metre/sec)

= (kg*m*m/sec^3)

= (kg*m^2/sec^3)

= (20*10^2/5^3)  

= (2000/125)

= 16 watts
