<u> Tides are lowest when</u>:
Tides are lowest when the earth, sun and moon come’s in a right angle. It occurs when the greatest pint in the wave or can called the crest arrives at the coast, the coast can feel the high tide, but when the smallest point i.e. trough arrives at the coast feels the low tide. The tidal force present makes the earth also the water to swell out of side which is often nearer to moon and the side farthest to that of moon, when no swelling can be seen low tides occurs.
Gravity is pulling you down and friction is slowing you down so you don't plummet to the ground at super high speeds.
Answer:
1.00029
Explanation:
A wave is a disturbance which travels through a medium and transfers energy without displacing the medium itself.
interference is one of the characteristics of a wave motion
The Michelson interferometer produces interference fringes by splitting a beam of monochromatic light so that one beam strikes a fixed mirror and the other a movable mirror. When the reflected beams are reflected, an interference pattern results.
∝Δm=Δud
∝=wavelength 500nm
Δm=number of fringes
d=length 9f the Michelson interferometer chamber
Δu= change in refractive index
500*10^-9*29=0.05*Δu
Δu=0.00029
REFRACTIVE INDEX=1+0.00029
refractive index=
1.00029
The first ariplanr was made December 17, 1903
Answer:
49N
Explanation:
F=ma
We know the mass is 5kg, and since the ball is suspended on one cable, the acceleration is g, 9.8m/s^2
F=5kg*9.8m/s^2
= 49N
Hope this helps!
