Textbook Question
Chapter 7, Problem 15EAP
Does it Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.
15. Comets in the Kuiper belt and Oort cloud have long, beautiful tails that we can see when we look through telescopes.

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
What is Tidal Energy?
What are two advantages associated with tidal energy?
What are two disadvantages associated tidal energy?
What kind of machinery/apparatus can we use to convert tidal energy into electricity?
A new social media fad claims that babies born under a new Moon (the so called newmies) develop into students that do better in school than children that were born under different lunar phases. Describe how this idea does or does not align with each of the three hallmarks of science. Is the idea of academic superiority for newmies falsifiable? How could you test the newmie conjecture ?

- Impact Energy. Consider a comet about 2 kilometers across with a mass of 4 × 1012 kg. Assume that it crashes into Earth at a speed of 30,000 meters per second (about 67,000 miles per hour). a. What is the total energy of the impact, in joules? (Hint: The kinetic energy formula tells us that the impact energy in joules will be 1 × m × v2, where 2 m is the comet’s mass in kilograms and v is its speed in meters per second.) b. A 1-megaton nuclear explosion releases about 4 × 1015 joules of energy. How many such nuclear bombs would it take to release as much energy as the comet impact? c.
