There are many things that we do in our daily lives that involve energy changes. For example ,when you hold your textbook in the air, you are giving it potential energy. Another example is an object in simple harmonic motion. Energy is constantly being transferred from one from to another, potential to kinetic.
Answer:
A change in pressure at any point in an enclosed fluid at rest is transmitted undiminished to all points in the fluid. With that said; in a hydraulic brake system, if the piston in the master cylinder(the part your foot pushes on) is one inch square area and you push with 100 pounds, then 100 pounds per square inch is transmitted to all parts of the hydraulic system. Now if the brake caliper piston(the part that pushes against the brake pad) is 2 square inches then there will be a total of 200 lbs of force being applied by the wheel cylinder, because each square inch has 100 pounds pushing on it. This is basically how cars brake systems are designed in order to reduce the amount of force required by the driver.
Btw if u want to give 67 points u must multiply that by 2 since two people answer and they get half of 67. Im still happy with my 34 though!
Carbon is the answer. all hydrocarbures have to contain carbon.
According to the kinetic molecular theory, the pressure of a gas in a container will increase if the "number of collisions with the container wall increases".
<u>Option: A</u>
<u>Explanation:</u>
Pressure is characterized as force acting by area per unit. It is triggered by gas molecules bombarding on the container walls. Kinetic molecular theory suggests that gases are made up of large numbers of small particles with continuous movement. Here there are elastic collisions between gas particles and between particles and container walls. There are no forces of attraction among them because of the large spaces between the gas particles. The gas temperature relies on the particle's average kinetic energy.
True! all matter is made out of atoms & molecules
