Answer:



Explanation:
The power of sunlight at equator
is known to be = 
Distance = 1 Au = 
Thus; the power at equator = 
= 1367 W/m²
Now; at noon (sun overhead)

At 3 pm (Sun 45 degrees from overhead);

C) sunset and D) midnight.
We based our assumption on the notion that the incident angle at sunset and midnight be just below 90° ; for example . let say:

Answer:
63.0 x (6.02 x 10^23) = 3.79 x 10^25 atoms of gold
Explanation:
There are 6.02 x 10^23 representative particles in a mole of any substance. Multiply it by the number of moles, and you will get the number of representative particles (atoms, molecules, formula units)
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:
at d the charge will be 3q and at 3d it will be 9q
Explanation:
for V=Vp-V2d
V=KQ/d=K*6q/2d=3kq/d for potential to 2d at 6q be zero the Vp will equal 3kq/d; hence at d, Q=3q and at 3d, Q=9q
