5 0

Answer:

<u>Distance:</u> 9 km

<u>Displacement:</u> 3 km

Explanation:

Distance takes into account the entire path that, in this case, Preston walked, while displacement, considers only the difference between the initial and final point.

In the picture, the different paths represent as a whole the distance he covered (5+3+1), whereas, the start and final point represent displacement (3-0)

An element has two naturally occurring isotopes with atomic masses of 112.90 amu and 114.90 amu. The relative abundances of thes
Musya8 [376]

Answer:

C. 114.8 u

Explanation:

The atomic mass of X is the <em>weighted average</em> of the atomic masses of its isotopes.

We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its percent of the total).

Set up a table for easy calculation

0.0429 × 112.90 u =     4.843 u

0.9571  × 114.90 u = <u>109.97    u </u>

                 TOTAL = 114.8       u
