Answer: D
Explanation:
Cause removing excess waste from the body helps to maintain a steady health
This is a sneaky trick question, to help you discover whether you know
one of the differences between velocity and speed.
=======================================
If you make a list of the distances and directions, and ignore the times,
you find these:
4 - west, (3 + 1) - east . . . . . zero in the east/west direction
1.5 - north, 1.5 - south . . . . . zero in the north/south direction
This jogger went out, had a nice jog around the neighborhood,and ended up exactly where he started.
Average velocity = (distance between start point and end point) / (time)
IF the question asked for average SPEED, then you would need the total distance, and divide it by the total time. But it asks for VELOCITY, and <u>that</u> only involves the straight distance between the start point and the end point, regardless of the route taken in between.
The jogger ended up exactly where he started. The distance between start and end points was zero. Average velocity is (zero) / (time) . And that fraction is going to be <em><u>Zero</u></em>, no matter how long or how short the trip was, and no matter how much time it took.
Answer:
atomic number (Z)
Explanation:
The atomic number (Z) is equal to the number of protons in the nucleus. In a neutral atom, the number of protons is equal to the number of electrons. The mass number of an atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

or,
⇒ ![E_x = 9\times 10^9\times [\frac{6\times 10^{-9}}{15^2}\times \frac{9}{15}-\frac{8\times 10^{-9}}{20^2}\times \frac{16}{20} ]](https://tex.z-dn.net/?f=E_x%20%3D%209%5Ctimes%2010%5E9%5Ctimes%20%5B%5Cfrac%7B6%5Ctimes%2010%5E%7B-9%7D%7D%7B15%5E2%7D%5Ctimes%20%5Cfrac%7B9%7D%7B15%7D-%5Cfrac%7B8%5Ctimes%2010%5E%7B-9%7D%7D%7B20%5E2%7D%5Ctimes%20%5Cfrac%7B16%7D%7B20%7D%20%5D)
and,
