If you are asking for the weight then the formula is F=mg where f is weight m is mass and g is acceleration due to gravity.m=52kg and g=9.8m/s2(the gravity of earth)
F=52*9.8=509.6
therefore the weight of the object is 509.6N
This is in the thermosphere which is at an altitude of 85-520km
The correct answer is A. Solid Rock
I would say that I and IV because summer is I and fall is IV
