An aluminum rod is 22.5 cm long at 20°C and has a mass of 350 g. If 13,000 J of energy is added to the rod by heat, what is the change in length of the rod in mm?

I have tried this at least 3 times with help...and my answer is very close...but still not right.

A uniform solid marble, of mass m = 20.0 g and diameter 1.00 cm, rolls without sliding down a large symmetric steel bowl, starting from rest at point A, at the top of the left(no-slip) side. The top of each side is a distance h = 15.0 cm above the bottom of the bowl. The left half of the bowl is rough enough to cause the marble to roll without slipping, but the right half of the bowl is frictionless...

Finding the Spring Constant We can describe an oscillating mass in terms of its position, velocity, and acceleration as a function of time. We can also describe the system from an energy perspective. In this experiment, you will measure the position and velocity as a function of time for an oscillating mass and spring system, and from those data, plot the kinetic and potential energies of the system. Energy is present in three forms for the mass and spring system....
