In the "mass in motion" lab, a ball was rolled down a ramp to see how far it moved a cup.
what did this experiment demonstrate?
an object´s momentum decreases with velocity.
an object´s momentum increases with velocity.
an object´s mass increases velocity.
an object´s mass decreases velocity.

An object´s momentum increases with velocity

Explanation:

Mass in motion is a short phrase to describe the term momentum.

Momentum of a body explains the tendency of such an object to continue moving. It is expressed as the produce of mass and velocity of a body:

                Momentum = mv

The momentum of a body is directly proportional to its mass and velocity. Therefore, an object's momentum increases with both mass and velocity. The greater the momentum a body has, the greater the force it will exert on a body it hits.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
