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:
337.5m
Explanation:
<u>Kinematics</u>
Under constant acceleration, the kinematic equation holds:
, where "s" is the position at time "t", "a" is the constant acceleration, "
" is the initial velocity, and 
is the initial position.
<u>Defining Displacement</u>
Displacement is the difference in positions: 
or 
<u>Using known information</u>
Given that the initial velocity is zero ("skier stands at rest"), and zero times anything is zero, and zero plus anything remains unchanged, the equation simplifies further to the following:
So, to find the displacement after 15 seconds, with a constant acceleration of 3.0 m/s², substitute the known values, and simplify:
![\Delta s=\frac{1}{2}(3.0[\frac{m}{s^2}])(15.0[s])^2](https://tex.z-dn.net/?f=%5CDelta%20s%3D%5Cfrac%7B1%7D%7B2%7D%283.0%5B%5Cfrac%7Bm%7D%7Bs%5E2%7D%5D%29%2815.0%5Bs%5D%29%5E2)
![\Delta s=337.5[m]](https://tex.z-dn.net/?f=%5CDelta%20s%3D337.5%5Bm%5D)

Answer:
0.39 
Explanation:
Parameters given:
Mass of car, m = 940 kg
Speed of car, v = 11.8 m/s
Power supplied by engine, P = 4300 W
To get the acceleration, we must define the relationship between Power and velocity.
Power, P, is given in terms of velocity, v, as:
P = F * v
where F = force
This is because Power is given as:
(where E = energy. t = time taken, d = distance moved)
Force, F, is given as:
F = m*a
Therefore, Power will be:
P = m * a * v
Acceleration, a, will then be:
The acceleration of the car at that time is 0.39
Answer: you are the person in charge of building a nuclear power plant in Florida. your first choice is to select a site for building the power plant.
Explanation: To find the answer, we need to know more about the nuclear power plants and the criteria to select the site for power plant.
<h3>
What you mean by nuclear power plants?</h3>
- Nuclear power can be defined from the nuclear fission reaction.
- These power plants will heat the water to produce steam and this steam is used to spin large turbines and thus generates electricity.
<h3>How to select the site for nuclear power plant?</h3>
- We have to consider the following things,
- keep distance from populated area.
- distance from load center.
- Accessibility to site.
- Water availability and fuel availability.
- waste disposal.
Thus, we can conclude that, before building a nuclear power plant, our first choice should be to select a site.
