Answer:
![\sqrt{ \frac{2.3 *10^{-28} }{F} }](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Cfrac%7B2.3%20%2A10%5E%7B-28%7D%20%20%20%20%20%7D%7BF%7D%20%7D)
Explanation:
Total force = Force due to gravity + Force due to charges
Total force = ![\frac{GMm}{r^{2} } + \frac{kQq}{r^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BGMm%7D%7Br%5E%7B2%7D%20%7D%20%2B%20%5Cfrac%7BkQq%7D%7Br%5E%7B2%7D%20%7D)
r is the separation between particles.
Charge of a proton(Q) = - (charge of an electron(q) ) = 1.6 * 10^-19 coulombs
Mass of a proton (M)= 1.67×10^-27 kilograms
Mass of an electron (m) =9.11 × 10^-31 kilograms
G=6.67 ×10^−11 N⋅m^2/kg^2
k=8.99 * 10 ^9 N.m^2 / C^2
Plugging in values:
Force due to gravity= (6.67 *10^−11)(1.67 * 10^-27)*(9.11 * 10^-31) /r^2 =1.01 * 10^-67 / r^2
Force due to charges : (8.99 * 10 ^9)*(1.6 * 10^-19)*(1.6 * 10^-19) / r^2 = 2.3 *10^-28 / r^2
We can observe that force due to charges is too large as compared with force due to charge. The ratio of Fc to Fm is 2.3* 10^39. It means that we can ignore force due to gravity.
Total force = Force due to charges.
F = 2.3 *10^-28 / r^2
r = ![\sqrt{ \frac{2.3 *10^{-28} }{F} }](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Cfrac%7B2.3%20%2A10%5E%7B-28%7D%20%20%20%20%20%7D%7BF%7D%20%7D)
Normal cells stop growing (reproducing) when enough cells are present. For example, if cells are being produced to repair a cut in the skin, new cells are no longer produced when there are enough cells present to fill the hole (when the repair work is done).
In contrast, cancer cells don’t stop growing when there are enough cells present. This continued growth often results in a tumor (a cluster of cancer cells) being formed.
ifif you look at the fish you could see what the difference is because some of them are reptiles or they're just amphibians but in the dichotomous key you can tell by looking at them that you can know what fish goes into the dichotomous key
