A large grinding wheel in the shape of a solid cylinder of radius 0.330 m is free to rotate on a frictionless, vertical axle. A constant tangential force of 290 N applied to its edge causes the wheel to have an angular acceleration of 0.854 rad/s2. (a) What is the moment of inertia of the wheel?
kg · m2

(b) What is the mass of the wheel?
kg

(c) If the wheel starts from rest, what is its angular velocity after 5.80 s have elapsed, assuming the force is acting during that time?
rad/s

The correct answer is cohesion and adhesion.

Explanation: The moving of water up in a straw is very well explained by the capillary action.

Capillary action is defined as the ability of a fluid to flow in narrow spaces due to cohesive and adhesive forces which are interacting between the fluid and surface.

Cohesive forces are the forces present between the liquid particles to resist separation.

Adhesive forces are the attractive forces present between the particles of different substances.

In a straw, adhesive forces are acting between the straw surface and water molecules and cohesive forces are acting between the water molecule. These two forces helps the water to move up in a straw.
