Evaluate (754 mm )/(43 s ) to three significant figures and express answer in si units using an appropriate prefix.

solution:

According to the question we need to convert it into SI units.

= 754 mm / 43 s

= 754 * 10 ^ -3 m / 43 s

=0.017534 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.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
