The sizes of cells in living organisms on Earth has been shown to be governed by the strength of the gravitational field near the Earth's surface. In animal cells, a maximum diameter ofkg,10 µm can be attained before auxilliary scaffold-like structures are needed to maintain the structural integrity of the cell. In our solar system, Jupiter's moon Europa (mass 4.80 × 1022radius 1560 km) and Saturn's moon Enceladus (mass 1.08 × 1020 kg, radius 252 km) are thought to have global oceans under a thick layer of surface ice. Because of tidal heating by theplanets they orbit, these moons may have all of the necessary ingredients for life. If microbial life were to have developed on Europa and Enceladus, and cell size scales linearly with thestrength of the gravitational field, what is the maximum size (in um) that Europan and Enceladean cells can attain without needing scaffold-type support?(a) Europan cellsum(b) Enceladean cellsum

Given, MEuropa = 4.80 × 1022 kg REuropa = 1560 km MEnceladus = 1.08 × 1020 kg REnceladus = 252 km…

Tidal forces are gravitational forces exerted on different parts of a object by a second object. Their effects are particularly visible on Earth's surface in the form of tides. To understand the origin of tidal forces, consider Earth-Moon system to consist of two spherical bodies, each with a spherical mass distribution. Let RE be the radius of Earth, m be the mass of the Moon, and G be the gravitational constant. Part B Since the gravitational force between two bodies decreses with distance, the accelaeration a(near) experienced by a unit mass located at the point on the earth's surface closest to moon is slightly different from the acceleration a(far) experienced by a unit mass located at the point on the earth`s surface farthest from the moon. Give a general expresion for the quantity a(near)- a(far).
