Two wires are tied to the 300g Sphere as shown in figure below. The sphere revolves in a horizontal circle at constant speed of 7.5 m/s.
A) Find the radius of the circle. Take your x-axis along R, and by using Newton%u2019s second law along x and y axes.
B) Calculate the centripetal acceleration
C) Find the tension in each wire.
Some air is flowing from a wider tube to narrower. There is a difference in height of the liquid in the two sides of the U-shaped tube. Why is there such a difference in height.
