36J/ 1s=36W
The strength required for a classmate to sweat and dissipate heat is:
36w-33w=3W
The amount of heat a classmate needs to emit through sweating in one hour is:
3W*3600s= 10800J
1 g sweat can dissipate heat as follows:
4320J/ 18g
The total amount of sweat required is:
10800j/(4320j/ 18g)= 45g
Students, study hard and don't answer such simple questions. . . .
