Answer:
centripetal acceleration of the ball is 6.9 m/s/s
tangential speed of the ball is 2.2 m/s
Explanation:
As we know that ball complete 5 rotations in 10 seconds
so frequency of rotation of ball is given as
now we know that angular frequency is given as
Now centripetal acceleration is given as
now the velocity of the ball at this angular frequency is given as
Answer:
low amplitude hope it will help you
Answer:
Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture is up) is limited by surface tension and, of course, gravity.
It is orbiting the object.
<u>Answer
</u>
d. both the volume and the number of particles are constant.
<u>Explanation
</u>
Temperature increases the kinetic energy of the molecules. This increases the velocity of the molecules hence increasing the number of collisions with the walls of the container. This causes the pressure in the container to increase.
This will only happen if other factors are held constant. These factors are volume of the container and the number of particles/molecules.
