Textbook Question
Chapter 10, Problem 61EAP
Escape from Venus.
- Calculate the escape velocity from Venus’s exosphere, which begins about 200 kilometers above the surface. (Hint: See Mathematical Insight 4.4.) b. Calculate and compare the thermal speeds of hydrogen and deuterium atoms at the exospheric temperature of 350 K. The mass of a hydrogen atom is 1.67 × 10-27 kilogram, and the mass of a deuterium atom is about twice the mass of a hydrogen atom. C. In a few sentences, comment on the relevance of these calculations to the question of whether Venus has lost large quantities of water.

We think the terrestrial planets formed around solid “seeds” that later grew over time through the accretion of rocks and metals.
a) Suppose the Earth grew to its present size in 1 million years through the accretion of particles averaging 100 grams each. On average, how many particles did the Earth capture per second, given that the mass of the Earth is = 5.972 × 10 ^24 kg ?
b) If you stood on Earth during its formation and watched a region covering 100 m^2, how many impacts would you expect to see in one hour. Use the impact rate you calculated in part a. You’ll need the following as well: the radius of the Earth is = 6.371 × 10 ^6 m and the surface area of the Earth is 4??^2Earth
