Answer:

small marble

Explanation:

A nonpareil are confectionery tiny ball items that are made up of starch and sugar. It is very small of the size of sugar crystal or sand grains. They were the miniature version of the comfits. They are generally opaque white but bow available in all colors.

In the context, if the nucleus is compared to the size of a nonpareil then its atom would be of the size of small size marble. An atom is bigger in size than that of nucleus as the nucleus is located inside the atoms.

Two point charges are on the y axis. A 4.50-σC charge is located at y=1.25 cm , and a -2.24-σC charge is located at y=-1.80 cm.

kvasek [131]

Two point charges are on the y axis. A 4.50-σC charge ( $q_1$ ) is located at y=1.25 cm ( $r_1$ ) , and a -2.24-σC charge ( $q_2$ ) is located at y=-1.80 cm ( $r_2$ ).

The total electric potential at the origin is $2.12\times10^6V$ .

How to calculate the total electric potential at the origin?

The total electric potential at some point due to several point charges is represented by:

$V=k_e \sum _i \frac{q_i}{r_i}$

Here,

$k _e= 8.988 \times 10^9 N \cdot m^2/C^2$ (Columbic constant)

The total electric potential at point $O$ is the sum of the potentials due to $q_1$ and $q_2$ will be:

$V_O=k_e(\frac{q_1}{r_1} +\frac{q_2}{r_2} )$

Substituting the values, we get:

$V_O=8.988\times10^9(\frac{4.5 \times 10^{-6}}{0.0125} +\frac{-2.24\times10^{-6}}{0.018} )=2.12\times10^6V$

Hence, the total electric potential at the origin is $2.12\times10^6V$ .4

Each Celsius degree is the size of 1.8 Fahrenheit degrees. So you need dip your Fahrenheit thermometer into the sample, see where you're starting, and then warm it up to a temperature that reads (37.1 x 1.8) = 66.8 Fahreheit degrees higher.
