Identify the incorrect statement about a single motor unit.- fine motor skills depend on the development of small motor units.- the smaller the number of muscle fibers, the more precise the movement.- muscle fibers of one motor unit intermingle with the fibers of another motor unit.- some motor units include as many as 2000 muscle fibers.- the more neurons involved, the more powerful the contraction.

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

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
