The outward pressure of hot gas in the Sun
A) is balanced by the inward gravitational pressure.
B) is increasing the Sun's diameter.
C) is cooling the photosphere.
D) is responsible for variations in the sunspot cycle.
E) weakens the magnetic field.
Question 2
Compared to Ida, Eros, and Gaspra, what was odd about Mathilde?
A) It had a small moon, so we could more accurately find its mass.
B) It was much denser, probably made of iron and nickel, a class M asteroid.
C) It was less dense than water, indicating it was a comet nucleus, rather than an asteroid.
D) It was less dense than rock, but more than ice, suggesting a porous structure.
E) It was the same density as the Earth's Moon, indicating it had been knocked off our Moon.
