a) 0 blocks
b) 6 blocks
c) 10 blocks
d) 16 blocks
susan walks her dog around the neighborhood. she walks 3 blocks north, 5 blocks east, 2 blocks south, 3 blocks west, 1 block south, and 2 blocks west to end up back at her house. what is her total distance covered?
a) 0 blocks
b) 6 blocks
c) 10 blocks
d) 16 blocks

The correct answer is option D.

Explanation:

Number blocks moved north ,= a = 3

Number blocks moved east = b =  5

Number blocks moved south = c =  2

Number blocks moved west = d =  3

Number blocks moved south =  e = 1

Number blocks moved west = f =  2

Total distance covered by Susan = a+b+c+d+e+f

= (3 + 5 + 2 + 3 + 1 + 2)blocks = 16 blocks

16 blocks is her total distance covered.

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.
