(a) Calculate the magnitude of the gravitational force exerted by Mars on a 80 kg human standing on the surface of Mars. (The mass of Mars is 6.4multiply1023 kg and its radius is 3.4multiply106 m.)
(b) Calculate the magnitude of the gravitational force exerted by the human on Mars.
(c) For comparison, calculate the approximate magnitude of the gravitational force of this human on a similar human who is standing 4 meters away.
(d) What approximations or simplifying assumptions must you make in these calculations? (Note: Some of these choices are false because they are wrong physics!)
-Use the same gravitational constant in (a) and (b) despite its dependence on the size of the masses.
-Treat Mars as though it were spherically symmetric.
-Treat the humans as though they were points or uniform-density spheres.
-Ignore the effects of the Sun, which alters the gravitational force that one object exerts on another.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
