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
Answer:
Explanation:
Given
initially steam is at
and converted to
ice
Let m be the mass of steam
latent heat of fusion and vaporization for water is


Heat required to convert steam in to water at 

Heat required to lower water temperature to 



Heat required to convert
water to ice at
is





So this energy is equal to kinetic energy of bullet of mass m moving with velocity v




Answer:
3.69 m/s
Explanation:
Forces :
mgsin Θ - mumgcosΘ = ma
g x sinΘ - mu x g x cosΘ = a
9.8 x sin 21 - 0.53 x 9.8 x cos 21 = a
a = -1.337 m/s²
so you have final velocity = 0 m/s
initial velocity = ? m/s
Given d = 5.1 m
By kinematics
vf² = vo² + 2ad
0 = vo² + 2 x -1.337*5.1
vo = 3.69 m/s
Work = Force times Distance
W = Fd
Given W = 750J, F = 125N;
750 = 125d
Solving for d:
d = 750/125
d = 6
The box moved a distance of 6 meters.
