Aping pong ball with a mass of 2.20 grams rolls along a frictionless table with a velocity of 0.850 m/s. what is the momentum of the ping pong ball? 1.87 g m/s2.59 g m/s1.59 g m/s3.04 g m/s

The momentum of the ball is 1.87 g m/s.

Explanation:

Momentum of an object is defined as the product of mass of the object and the velocity of the object. Mathematically,

where,

p = momentum of the ball = ? g m/s

m = mass of the ball = 2.20 grams

v = velocity of the ball = 0.850 m/s

Putting values in above equation, we get:

Hence, the momentum of the ball is 1.87 g m/s.

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.
