In ball drop viscometry, what does it mean when the spherical ball falls down with a constant velocity?*2 pointsThe ball is not affected by any forcesThe gravitational force is balanced by the drag and buoyancy forcesThe gravitational force exceeds the drag and buoyancy forcesThe drag force is greater than the gravitational force

As a ball falls towards ground, its velocity _____

Ignoring air resistance, after being dropped the vertical velocity of a ball immediately before contacting a surface is dependent on: Question 18Answera.the height from which the ball was dropped and gravityb.the height from which the ball was dropped, gravity and the surface texture of the ballc.the height from which the ball was dropped, gravity, the mass of the ball, and surface texture of the balld.the height from which the ball was dropped, the mass of the ball, and surface texture of the balle.the influence of gravity, the mass of the ball and surface texture of the ball

A sphere is released from rest on a no-slip surface, as shown in the figure (the left side). After reaching its lowest point, the ball begins to rise again, this time on a frictionless surface as shown on the right side figure. When the ball reached its maximum height on the frictionless surface, it is It is impossible to tell without knowing the radius and mass of the ball. at the same height as when it was released on the left side. at a lesser height than when it was released on the left side. at a greater height than when it was released on the left side.

Explain the changes in the kinetic and potential energies as the ball falls to the ground.

A spherical solid ball of volume V is made of a material of density 1. It is falling through aliquid of density 2(2 < 1). Assume that the liquid applies a viscous force on the ball that isproportional to the square of its speed v, i.e. Fviscous = kv2(k > 0). The terminal speed of theball is:
