Well it's energy comes from the sun since the sun gives it sunlight to help it grow
To answer these questions just use the equations for potential energy using the mass and heights described. the potential energy at the prescribed heights = the initial kinetic energy required to reach that height.
Make sure you calculate the force of gravity on the surface using the radius of the planet.
Nope, color change can also occur during a physical change.

Answer:

Explanation:
Let:

We need to know for which value of
the function
is equal to
:

Therefore, we need to solve for the previous equation for
:
Replacing the values of
and
:

Subtract 4 from both sides:

Multiply both sides by -1

Divide both sides by 3:

Therefore the value of
for which
is
.
Verify the result:
