3) Consider a spherical planet in our solar system with radius, R, that behaves like a perfect blackbody, absorbing all of the sunlight hitting its surface and radiating light isotropically according to its temperature. At what range of distances from the Sun could this planet support liquid water on its surface? Hint: Solve for the equilibrium temperature of the planet where the light energy it absorbs equals the energy radiated away, and then find the distances where this temperature is...

The small spherical planet called "Glob" has a mass of 6.50×1018 kg and a radius of 5.60×104 m. An astronaut on the surface of Glob throws a rock straight up. The rock reaches a maximum height of 1.64×103 m, above the surface of the planet, before it falls back down. -What was the initial speed of the rock as it left the astronaut's hand? (Glob has no atmosphere, so no energy is lost to air friction. G = 6.67×10-11 Nm2/kg2.)...
