Answer:
No. of 100 W bulbs, n = 28,539 bulbs
Given:
Power of a single bulb = 100 W
Time period, T = 1 yr =
= 31,536,000 s
mass of matter, m = 1 g = ![1\times 10^{-3}]](https://tex.z-dn.net/?f=1%5Ctimes%2010%5E%7B-3%7D%5D)
Solution:
According to Eintein's mass-energy equivalence:
E = 
E = 
E = 
Power of a single bulb, P = 
P = 
P = 28,53,881 W
No. of 100 W bulbs, n = 
n = 
n = 28,539
