on sunday, a strong gale blows near beth’s house. the best estimate for the wind speed is miles/hour. note: one knot is about the same as 1.15 miles/hour.

The answer is: The best estimate for the wind speed is 47.15 - 54.05 miles/hour.

The knot is a unit of speed equal to one nautical mile per hour, approximately 1.15 mph.

The ISO standard symbol for the knot is kn.

v(wind) = 41-47 kn; speed of strong gale.

v(wind) = 41 · 1.15 mph.

v(wind) = 47.15 mph.

v(wind) = 47 · 1.15 mph.

v(wind) = 54.05 mph.

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.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
