Answer:
Number of electron on the fur will be 
Explanation:
We have given net charge on the fur 
Charge on one electron 
Let there are n number of electrons
So 


So number of electron on the fur will be 
Archaeologists use radioactive decay of an isotope of the element <u>carbon.</u> Because it has a fairly short half-life, and is found in anything that was once living.
<h3>What is radioactivity?</h3>
The act of producing radiation spontaneously is known as radioactivity. This is accomplished by an unstable atomic nucleus that want to give up some energy in order to move to a more stable form.
Archaeologists use radioactive decay of an isotope of the element <u>carbon.</u> Because it has a fairly short half-life, and is found in anything that was once living.
Hence, <u>carbon</u> is used the correct answer for the blank.

Answer:
<u></u>
- <u>See attached the ray diagram with the path of Ray 1, which must pass through the focal point, F.</u>
Explanation:
The <em>curved mirror</em> shown is a converging lens.
<em>To find the location and size of the image</em> formed by a converging lens, you must draw two rays: one ray is from the upper tip of the object (the pen in your figure) that is in front of the mirror, parallel to the horizontal axis until the lens (<em>Ray 1</em> in your figure) which then bends through the focal point (F in your figure). That is the ray that you must complete in your figure.
The attached figure shows this ray in blue.
The other ray would be from the upper tip of the pen straight through the center of the lens (this is not included in the figure, by instructions of the question).
