Answer:
Explanation:
100 W bulb is using energy of 100 J in one second.
22 percent of the electrical energy is transformed to radiant energy.
a )
So , electrical energy is transformed to radiant energy per second
= 100 x .22 = 22 J
energy transformed in one minute = 22 x 60 J
= 1320 J
b )
electrical energy is transformed to heat energy per second
= 100 x .78 = 78 J
energy transformed in one minute = 78 x 60 J
= 4680 J
