Answer:
F_net = 249.726 KN
Explanation:
We are given;
Depth; h = 350m
Diameter; d = 30cm = 0.3m
So,Radius; r = 0.3/2 = 0.15
To solve this problem, we'll say that the total pressure on the glass of the bell under this depth is equal to the pressure under this depth minus the pressure of air inside the glass window.
So,
P_portal on glass window = P - P_surface
Now, P is expressed as P = P_surface + ρgh
Thus,
P_portal on glass window = P_surface + ρgh - P_surface
So, P_portal on glass window = ρgh
Now, we want to calculate the net force. We know that, the formula for pressure is P = F/A.
Thus,
P_portal on glass window = F_net/A
Thus,
F_net/A = ρgh
F_net = ρghA
Where A is area = πr²
Density of sea water has a constant value of 1030 kg/m³
Thus, plugging in the relevant values,
F_net = 1030 x 9.8 x 350 x π x 0.15²
F_net = 249.726 KN
The answer is A. shorter wires
Answer:
Less powerful
Explanation:
Hurricanes rely on warm water. It sucks heat energy from the water to use for fuel. Warmer water means more moisture, which also mean a bigger and/or stronger hurricane. The North Atlantic is definitely much colder than the Caribbean so the hurricane will not have much fuel.
Have a great day!
