Question

Power of an electric bulb is 500 Watt. Express it in C.G.S. system

Answer 1

Answer:

we know dimension formula

o________________________

Power=Work/time=Energy /time

Dimension [P]= [ML^2T^-3]

n2 = n1 [M1/M2]^x [L1/L2]^2 [T1/T2]^-3

_______________________________

now convert SI unit into CgS unit

500w=500J/s

n2 = 500 [kg/g] [1m/cm]^2[1s/1s]^-3

=5*10^2*10^3 g*(10^2)^2 *(1s)^-3

=5*10^2*10^3*10^4 g cm^2 /s^3 =

5*10^9 g cm^2 /s^3.
