Given:
Power,
or,
[tex]= 4\times 745.7[/tex]
[tex]= 2982.8 \ W[/tex]
Time,
or,
[tex]= 1.5\times 60\times 60[/tex]
[tex]= 5400 \ s[/tex]
Now,
The increase in the internal energy:
= [tex]Power\times Time[/tex]
= [tex]2982.8\times 5400[/tex]
= [tex]1.61\times 10^7 \ J[/tex]
Thus the response above is right.
