Question

select all the correct answers.
accretion was one of the processes responsible for heating up earths core in the early years of the solar system. which two observations can be made about the process of accretion?
□ gravity increases as mass increases.
□ there is little or no transfer of energy.
□ frequency of collisions increases as gravity increases.
□ intensity of impacts decreases as gravity increases.
□ heat energy decreases as gravity increases.

Explanation:

Step1: Analyze the relationship between gravity and mass

According to Newton's law of universal gravitation \(F = G\frac{m_1m_2}{r^2}\), when the mass (\(m_1\) or \(m_2\)) of an object increases (assuming the distance \(r\) between objects remains relatively constant in the context of accretion in the early solar - system formation where particles are aggregating), the gravitational force \(F\) (gravity) increases. So, gravity increases as mass increases.

Step2: Analyze the relationship between gravity and collision frequency

As gravity increases (due to increasing mass of the growing protoplanet - like object during accretion), more particles are attracted. This leads to a higher frequency of collisions between the accreting particles and the growing body.

Answer:

Gravity increases as mass increases, Frequency of collisions increases as gravity increases.
