Without air resistance, there is no horizontal force on the projectile,
so it has no horizontal acceleration. The answer is "zero".
Given that,
Depth of seawater, h = 11,033 m
Density seawater, p (rho) = 1025 kg/m³
Gauge Pressure , P = ??
Since, we know that:
Pressure, P = pgh
Pressure = 1025 * 9.81 * 11033
Pressure = 1109395723.3 N/m²
or
Pressure = 1.1 x 10∧8 Pascal
<span>Oxygen and Nitrogen would be the most similar of the elements listed, because they are the closest in the periodic table. This isn't a very good reason for anything, but the two do have some similar properties. They are both non-metals, they are both highly electronegative, they are both diatmoic gasses in their natural states, they have a similar number of valence electrons, they are both generally oxidizing agents. Oxygen and Chlorine are also quite similar, but not quite as similar as Oxygen and Nitrogen.</span>
The energy that the man has gained in being lifted is 3000J which is in the form of potential energy.
<u>Explanation:</u>
Given:
Work done, W = 3000J
Height, h = 2.5m
Time, t = 0.4 seconds
Energy gained = ?
As the man gets lifted, it gains potential energy.
Potential energy will be equal to the work done by the elevator.
We know,
potential energy = mgh
Thus, the energy that the man has gained in being lifted is 3000J which is in the form of potential energy.
