The proper time would be the time measured in the rest frame of the event, so in this case the observer on mars would measure the proper time.
Answer: 26.6 J
Explanation:
The heat needed to raise the temperature of a solid body, using only a conductive process, has been empirically showed to be equal to the following expression:
Q= c . m. (t2 – t1)
where c= specific heat capacity (in J/gK), m= mass of the solid (in g) ,
and (t2 - t1)= difference between final and initial temperatures.
Replacing by the values, we get:
Q= 0.385 J/gK . 1,550 g. (77.5ºC – 33.0ºC)= 26.6 J
