What happens when there is a change in pressure at any point in a fluid

Answers

A change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and to the walls of the container. This is a statement of Pascal's Principle, which is the basis of the hydraulic jack you see lift cars at the garage.

A compact disc has a radius of 6 centimeters.a. What is its circumference in meters?
b. If the cd rotates 4 times per second, what is the linear speed of a point on the outer edge of the cd? Give
your answer in meters per second.
c. What is the linear speed of a point 3 centimeters from the center of the cd? (Assume the angular speed
has not changed).

Answers

Circumference is $2\pi{r}=37.7$ (approx.)
Speed is 4 times that. That is, 150.8 cm/s or 1.508 m/s.
If we get a point at distance 3 cm, we take the radius half of that. The circumference also gets half, so does the linear speed. We get 0.754 m/s or 75.398 cm/s.

What environmental factors affect kinetic energy and diffusion?

Answers

There are several environmental factors that affect the kinetic energy and diffusion. The environmental factors are temperature, molecular size, and pressure, nature of the material and the concentration of the material. All the mentioned factors directly impact the kinetic energy and diffusion of a material or compound or fluid. Temperature can generally increase the kinetic energy of molecules within a compound or a substance. Increase or decrease of temperature changes the shape and nature of the material concerned. So these natural factors have a big influence on the kinetic energy and diffusion.

Answers
Temparature
Humidity (Amount of molecules in the air)

Explanation
Examples of environmental factors are, temperature, wind, pressure, humidity etc. Kinetic energy is the energy possessed by a body in motion.
This motion can be affected by factors such as rain and humidity since the make the medium more dense. It require more energy to move in a denser medium.
Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. When temperatures are high the molecules get more energy and move more faster increasing the rate of diffusion.
