To answer this item, it is assumed that the gas in the cylinder is ideal such that it follows the equation,
PV = nRT
when V is to be calculated,
V = nRT/P
V = (4)(0.0821 L.atm/molK)(300 K) / (400 kPa/101.325 kPa/atm)
V = 24.95 L
Thus, the volume of gas in the cylinder is 24.95 L.
The answer is A. A positive particle inside the nucleus
Power = work /time
and W = force * dis
W = 96 * 3.046 J = 292.44 J
P = 292.44 / 4.6 = 63.575 watt
Answer:
solute + solvent = solution
Explanation:
solute is <em>Any substance that is dissolved in a liquid solvent to create a solution</em>
solvent is <em>A liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution.</em>
and.
solution is <em>A homogeneous mixture, which may be liquid, gas or solid, formed by dissolving one or more substances.</em>
The man is standing on the plank. Then he is pulling the rope towards himself. He pushes the plank forward with the legs so that he can pull the rope backwards.
The man is standing on the plank. Then he is pulling the rope towards himself. He pushes the plank forward with the legs so that he can pull the rope backwards. So the friction f acts in the forward direction for the plank. Also f acts in the opposite direction on the man. The tension T in the rope is 100 N (given). Let the friction force = f Newtons.

Let the friction force = f Newtons.Let the common acceleration = a m/s^2
Man: <em>net force = T - f = m a = 50 a </em>
<em>net force = T - f = m a = 50 a </em>
<em>Plank: net force = T + f = m a = 100 a</em>
<em>net force = T - f = m a = 50 a </em>
<em>Plank: net force = T + f = m a = 100 a</em>
<em>As T = 100 N, a = 4/3 m/s^2 and f = 100/3 Newtons. </em>
