Answer:
Explanation:
Given:
- width of door,
- height of the door,
- thickness of the door,
- mass of the door,
- torque on the door,
<em>∵Since the thickness of the door is very less as compared to its other dimensions, therefore we treat it as a rectangular sheet.</em>
- For a rectangular sheet we have the mass moment of inertia inertia as:
We have a relation between mass moment of inertia, torque and angular acceleration as:
Answer:
matter is the correct answer.
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.
