Answer:
A) the pressure could crush the submarine
Explanation:
- The submarines are mainly used for defense purposes.
- In world war 1 and 2 the submarines played a vital role in the war.
- The submarines work according to the principle of buoyancy.
- According to this principle, when seawater is filled inside the tank in a required amount, the submarines sink.
- When the seawater is expelled, the submarine rises to above the sea.
- Most of the time, it dives deep into the sea, the hydrostatic pressure should be taken into account.
- If the hydrostatic pressure is not considered, the pressure could crush the submarine.
Answer:
Explanation:
Given that,
Force force acting on the Skater's rocket is 220 N
Resistive force acting on it, F' = 30 N
Mass of Shelby, m = 60 kg
We need to find the acceleration of Shelby. Net force acting on Shelby is given by :
Net force = 220-30
= 190 N
The formula of net force is :
F = ma
a is acceleration of Shelby
So, the acceleration of Shelby is 
No but the sun could be a white dwarf stellar remnant.
By bring their legs close to their bodies, they are decreasing the length of the pendulum which help them move more quickly.
A pendulum is nothing but a body suspended from a fixed point so that it can swing back and forth under the influence of gravity.
Here in this case Gibbons are bringing their legs close to their bodies and reducing the length of the pendulum. Since as the length of the pendulum increases the speed of the movement will be reduced. By bringing their legs close to their bodies they are reducing the length and in turn their speed increase and they move quickly.
