Answer:
Option d (108,000 J) is the correct answer.
Explanation:
The given values are:
Power,
P = 120 Watts
Time,
t = 15 min.
i.e.,
= 900 sec
As we know,
⇒ [tex]P=\frac{W}{t}[/tex]
So,
⇒ [tex]W=P\times t[/tex]
On substituting the given values, we get
⇒ [tex]=120\times 900[/tex]
⇒ [tex]=108,000 \ J[/tex]
