If we compare the density and temperature of the Earth's mantle to the core, what differences can we expect as we move downward into the Earth? Both the temperature and pressure increase.

A.
Both the density and temperature increase.

B.
Both the density and temperature decrease.

C.
The density increases, and the temperature decreases.

D.
The density decreases, and the temperature increases.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
