Answer:
The velocity of water at the bottom, 
Given:
Height of water in the tank, h = 12.8 m
Gauge pressure of water, 
Solution:
Now,
Atmospheric pressue, 
At the top, the absolute pressure, 
Now, the pressure at the bottom will be equal to the atmopheric pressure, 
The velocity at the top, 
, l;et the bottom velocity, be 
.
Now, by Bernoulli's eqn:
where
Density of sea water, 
Answer:
they say yum yum as they eat planets and make humans starve
Explanation:
but they still eat them
they travel the speed of light or 300,000 km per second
Answer:
5.00 × 10^14 Hz
Explanation:
The wavelength of the light in the medium can be calculated by using the formula:
λ = v / f
Where;
λ = wavelength (m)
v = speed of light
f = frequency (Hz)
From the provided information, λ = 600 nm (600 × 10^-9m), v = 3 × 10^8m/s.
λ = v / f
λ = 3 × 10^8/600 × 10^-9
λ = 0.005 × 10^(8+9)
λ = 0.005 × 10^17
λ = 5.00 × 10^14 Hz
The frequency of the light in the medium is 5.00 × 10^14 Hz
A main sequence star burns hydrogen to helium. Once a main sequence star exhausts all of the hydrogen, it begins to expand and burn helium causing if to become a red giant.
