Homework Answers
Option A
Since speed of gas is depends on temperature and directly proportional to temperature.
At fixed temperature, all have same speed irrespective of gas

The kinetic theory of gases states that the kinetic energy of a
gas is directly proportional to the temperature of the gas. A
relationship between the microscopic properties of the gas
molecules and the macroscopic properties of the gas can be derived
using the following assumptions: The gas is composed of pointlike
particles separated by comparatively large distances. The gas
molecules are in continual random motion with collisions being
perfectly elastic. The gas molecules exert no long-range forces on
each...

4) The diagrams below show a ball swinging on a string. The diagrams show the ball's position at equal time intervals. The first position is when the ball is moving up and left. Copy these into your lab notebook and then draw acceleration vectors for the ball on each one the acceleration points the way you drew it for each diagram. The arrows show the ball's relative speed and direction at each instant and turnaround points have...

Learning Goal: To be able to interpret potential energy diagrams
and predict the corresponding motion of a particle. Potential
energy diagrams for a particle are useful in predicting the motion
of that particle. These diagrams allow one to determine the
direction of the force acting on the particle at any point, the
points of stable and unstable equilibrium, the particle's kinetic
energy, etc. Consider the potential energy diagram shown. (Figure
1) The curve represents the value of potential energy U...
