Fluorescence can be defined as the phenomenon by which an object emits visible light when placed in front of ultraviolet light. In fluorescence, the absorbed light increases the energy band of the electrons, causing them to go into a more excited state. The electrons, before they release the absorbed energy in the form of light, lose a part of the energy due to the vibration of the molecules. When they return to their initial state, the electrons will emit light.
While microwaves are electromagnetic waves whose frequency is high, and are used for the transmission of high-speed telegraphic signals and for the communication of satellites and do not emit light.
Ben's average speed was twice Debby's average speed.
Explanation:
Ben covered a total distance of 16 miles (10+4+2) and Debby covered 8 miles (3+2+2+1) which is half of what Ben covered. As they both reached the place in the same amount of time it tells us Ben was faster.
It's 12.1 m/s, assuming that's the launch velocity that's given. For projectile motion, velocity's y-component is parabolic/quadratic. It's x-component is constant, so you don't need to know it.
Assemblage is an additive process where artists construct work by putting together objects and attaches them in some way. The correct option among all the options that are given in the question is the second option or option "b". This kind of artistry actually gives a three dimensional impression to the work that is done by the artist.
