id be scared because this thing is moving by its self at an alarming rate
Explanation:
Answer:
a) It reduces the kinetic energy loss of the stunt person.
Answer:
Explanation:
The simplest kinetic model is based on the assumptions that:
(1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size;
(2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the walls of the container, but otherwise do not interact; and
(3) the transfer of kinetic energy between molecules is heat. These simplifying assumptions bring the characteristics of gases within the range of mathematical treatment.
<h2>From kinetic theory of gases, the pressure exerted by a gas is given by velocity of gas molecules. m = Mass of each molecule of a gas. But by assumptions of the kinetic theory of gases the average kinetic energy of a molecule is constant at a constant temperature.</h2>
To consider the molecule in gas at rest, suppose a container of gas at rest.
We know that velocity is a vector quantity and it includes direction but speed is a scalar quantity and it does not include a direction.
Although the molecules are moving around a lot, they are only moving around within the fixed walls of the container. As the container isn't moving (given), the net velocity of the gas molecules is zero. Think about their random movements as vectors, then think about adding up all those vectors over time. They cancel each other out over time. So, the average velocity of a molecule in gas at rest is zero.
But it's only the directions that cancel each other out, which is why the average speed (ignoring direction) is non-zero.
