Answer:
434.0 V/m
Explanation:
The power output of the laser is:
while the radius of the beam is
so the cross-sectional area is
So the intensity of the laser beam is
The intensity of a laser beam is related to the magnitude of the electric field by
where
c is the speed of light
is the vacuum permittivity
Solving the formula for E, we find
I would let someone more confident in this field to answer this question but that sounds like a Chemical reaction
The air would contract therefore the answer is the second choice.
Galileo discovered during his inclined-plane experiments that a ball rolling down an incline and onto a horizontal surface would roll indefinitely.
