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)
It is a plant cell because it has chloroplasts. Only plant cells has these.
Answer:
d. in both the progeny of that individual cell and the individual cell itself
Explanation:
Somatic mutations occur in the somatic cells of the individuals. Since the genetic material of the somatic cells is not passed to the next generation of an organism, the somatic mutations do not appear in the progeny of an individual.
Somatic cells divide by mitosis which in turn maintains the identity of DNA between the parent and the daughter cells. Therefore, the new cells derived from a mutated somatic cell would also carry the same mutation.
The answer is A because if the regulating substance that enter and exit the nucleus
