Water is boiling in a clear pot, as shown in the picture. How do the water molecules closest to the burner compare to the water molecules closest to the surface of the liquid? They are more spread out and moving faster than those at the surface. They are closer together and moving faster than those at the surface. They are more spread out and moving slower than those at the surface. They are closer together and moving slower than those at the surface.

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.
