At the end of a delivery ramp, a skid pad exerts a constant force on a package so that the package comes to rest in a distance d. The ramp is changed so that the same package arrives at the skid pad at a higher speed and the stopping distance is 2d. Part A What happens to the time interval required for the package to stop?

The time interval increases by a factor of 2.

The time interval decreases by a factor of 2.

The time interval increases by a factor of ?2.

The time interval doesn't change.

The time interval decreases by a factor of 2?.

Groups of organs that work together to complete a process in the body are called: a. cells b. tissues c. nerves d. systems

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
