Answer:
The volume is 
Explanation:
From the question we are told that
The depth below the see is 
The density of the sea is 
The temperature at this level is 
The volume of the air bubble at this depth is 
The temperature at the surface is 
Generally the pressure at the given depth is mathematically evaluated as
Where 
is the atmospheric pressure with a constant value
substituting values
According to the combined gas law
=> 
=>
Answer:
true
Explanation:
The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected. In the Northern Hemisphere, wind and currents are deflected toward the right, in the Southern Hemisphere they are deflected to the left.
Answer:
The tension is 75.22 Newtons
Explanation:
The velocity of a wave on a rope is:
(1)
With T the tension, L the length of the string and M its mass.
Another more general expression for the velocity of a wave is the product of the wavelength (λ) and the frequency (f) of the wave:
(2)
We can equate expression (1) and (2):
=
Solving for T
(3)
For this expression we already know M, f, and L. And indirectly we already know λ too. On a string fixed at its extremes we have standing waves ant the equation of the wavelength in function the number of the harmonic 
is:
It's is important to note that in our case L the length of the string is different from l the distance between the pin and fret to produce a Concert A, so for the first harmonic:
We can now find T on (3) using all the values we have:
If the boat's speed is s, and the river's speed is r, and the boat is traveling east (0 degrees),
(0,r) + (s cos297,s sin297) = (6,0)
now just solve for r and s.
