Expert Solution & Answer

Answer to Problem 1QP

Option (c) is correct. The planetesimals that disappeared may have now become the part of the larger bodies like planets and moons.

Explanation of Solution

As the solar system formed, there were a huge number of planetesimals formed along with the formation of the planets. The planetesimals are the bodies that revolve around the sun along with the other planets but are comparatively smaller.

The asteroids, comets are the left over planetesimals that survived after the formation of the solar system. The other planetesimals those were present at the initial stages after the formation of the solar system might not exist now.

The reason behind the disappearing of the several planetesimals is that they might have collided with the larger bodies like planets or their moons due to their gravitational interaction and have become the part of that particular body.

Conclusion:

Thus, option (c) is correct. The planetesimals that disappeared may have now become the part of the larger bodies like planets and moons.

Option (a) is incorrect. The planetesimals that are far away from the sun do not receive much heat from the sun be evaporated.

Option (b) is incorrect. In order to left the solar system, the inner planetesimals might have to undergo several difficulties.

Option (d) is incorrect. All the planetesimals did not undergo collisions to break into fragments.

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
Which of the following statements accurately describes our current understanding of the solar system? a. There are no metals in the solar system beyond Jupiter and its orbit. b. Terrestrial worlds are so small because their large atmospheres were stripped away in time by Jupiter. c. Jupiter and Saturn are made of strictly a combination of hydrogen and helium, and both objects lack a planetary core. d. Various ices can contribute to the mass of planetary cores if we are at a great enough distance from the sun.
15)Based on the information found in modules 2.1 , 2.2 AND 2.3 put the following statements about the formation of the Solar system based on the NEBULAR HYPOTHESIS in the correct order from 1. ‘’OLDEST EVENT’’ (first to form according to the Nebular hypothesis) to 5. ‘’YOUNGEST EVENT’’ (Last to form in the Solar system, based on the sequence of events listed) . • Clusters of molten metals and dust particles stuck together to form rocks • Lighter gases were swept away from center of solar system into outer solar system • One to two proto-planets collide to form our Moon • Mutual gravity caused rocks to come together, eventually to form protoplanets • Heavier rocky material, with metallics with higher melting points are left nearer to sun
