E is the answer because there’s not enough information to answer the question
Answer:
the fractional loss per pass =0.053
the decay time of the cavity =11 ns
Explanation:
laser is an acronym for Light Amplification by Stimulated Emission of Radiation and it has lot of military applications : basically ranging from target acquisition, fire control, and training. It is also being used in LIDAR communications, radar systems , laser guided landing systems, laser pointers, holography, photography, guidance systems, scanning machines, metal working, and medicine.
the fractional loss per pass= 
but no excited state absorption, therefore 
is 0
=0.053
b) the decay time of the cavity:
=1.1 *10^-8 seconds
=11 ns
Recall that average velocity <em>v</em> is given by
<em>v</em> = ∆<em>x</em>/∆<em>t</em>
where ∆<em>x</em> is displacement and ∆<em>t</em> is time.
Under constant acceleration, average velocity is also equal to the average of the initial and final velocities,
<em>v</em> = (<em>v</em>₂ + <em>v</em>₁)/2
The player starts at rest, so <em>v</em>₁ = 0, and speeds up to <em>v</em>₂ = 5.45 m/s in a matter of ∆<em>t</em> = 3.02 s. So
∆<em>x</em> = (<em>v</em>₂ + <em>v</em>₁) ∆<em>t</em> / 2
∆<em>x</em> = (5.45 m/s) * (3.02 s) / 2
∆<em>x</em> ≈ 8.23 m
A compass would work differently on the moon than the Earth because Earth's magnetic field is between 25,000 and 65,000 NanoTeslas. Whereas, the Moons magnetic field is about 2,500-6,500 and some parts of the moon have nonexistent magnetic fields.
