Timmy pushes off of the pool wall with a force of 2300 N and accelerates at 15 m/ what is mass? (ignore water resistance)
use one decimal place in your answer
Please help!

Mass = 153.33 Kg

Explanation:

Given:

Force = 2,300 N

Acceleration = 15 m/s²

Find:

Mass

Computation:

Mass = Force / Acceleration

Mass = 2,300 / 15

Mass = 153.33 Kg

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.
