Question

find the value of 10W on system having 100gm , 20 sec , amd 1min. th3 fundamental unit​

Answer 1

Explanation:

Here, n1=100J

M1=1kg,L1=1m,T1=1s

n2=?M2=100g,L2=10cm,T2=30s

An energy = [ML2T−2]∴a=1,b=2,a=−2

n2=n1(M1M2)1(L1L2)2(T1T2)−2

=100(1kg100g)−1(1m10cm)2(1s30s)−2

=100×10×102×30×30

n2=9×107 new units of energy
