Involleyball can the ball ever touch the floor?

In volleyball, the ball can touch the floor as long as it is within the boundaries of the court and it is not the result of an illegal play, such as a lift or a carry. When a team successfully spikes the ball onto the opponent's side and it touches the floor, it results in a point being awarded.


How many times can a player bounce the ball in handball?

A player can bounce the ball as many times as they like while moving, as long as they do not hold the ball for more than three seconds.


Will heat deflate or inflate a ball?

Heat can cause the air inside a ball to expand and inflate the ball. Conversely, if a ball is exposed to extreme heat for a long period of time, it can potentially weaken the materials, causing it to lose pressure and deflate.


Two equally charged balls each of mass 0.1gram are suspended from the same point by thread 13cm long the balls come to rest 10cm apart due to repulsion.determine the charge on each ball?

By using the formula for electrostatic force and equating it to the tension in the string, we can find the charge on each ball. The electrostatic force is given by Coulomb's law, F = k*q^2/r^2, where k is the electrostatic constant, q is the charge, and r is the separation. Equating this force to the tension in the string, we can solve for the charge on each ball.


How does a falling ball viscometer measure viscosity of a fluid?

A falling ball viscometer measures the viscosity of a fluid by timing how long it takes for a ball to fall through the fluid. The viscosity of the fluid affects how quickly the ball falls, with more viscous fluids causing the ball to fall more slowly. By measuring the time it takes for the ball to fall, the viscometer can calculate the viscosity of the fluid.
