Assume all the balls in the answer choices are the same. Which one has the most gravitational potential energy? Select one:

A ball sitting on top of a mountain, 10,000 feet above the ground.

A ball sitting on a table, 3 feet above the ground.

A ball sitting on the ground.

A ball sitting on a ladder, 10 feet above the ground.

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.

Ajoint produces movement when its angle decreases. which type of movement is it?
