Answer:
42.0×10² second²
Explanation:
Here, time is given in milisecond
(64800 ms)²
= 4199040000 ms²
The SI unit is seconds
1 second = 1000 milisecond



42.0×10² second²
 
        
             
        
        
        
Answer:
  =118.8 K= 154.2°C
=118.8 K= 154.2°C
Explanation:
COP_max of carnot heat pump= 
where T_H and T_C are temperatures of hot and cold reservoirs
Also COP=
in the question 
⇒
heat is added directly to be as efficient as via heat pump 
 
and T_H= 24° C= 297 K

on calculating the above equation we get 
 =118.8 K
=118.8 K
the outdoor temperature for efficient addition of heat to interior of home 
  =118.8 K= 154.2°C
=118.8 K= 154.2°C
