It is 5.5 kmkm from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/hkm/h (which uses up energy at the rate of 700 WW), or you could walk it leisurely at 3.0 km/hkm/h (which uses energy at 290 WW). Part A Which choice would burn up more energy

Which two objects have the greatest gravitational force acting between them

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.

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
