Accretion was one of the processes responsible for heating up Earth’s 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.

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
