Answer: In a vacuum
Explanation:
The speed of light in a vacuum is but it is approximated to , and this value is a constant which has been denoted as .
However, in other media different from vacuum, the speed of light will depend on its molecular structure, specifically on its electromagnetic properties, its electrical permittivity and magnetic permeability.
In addition, it is important to note that in these materials or media different from vacuum, the speed of light will be less than and will depend on the medium's index of refraction.
Answer:
195N
Explanation:
F1*b1=F2*b2
F2=F1*b1/b2; F2=45*13/3=195N
Thank you for posting your question here at brainly. I think your question is incomplete. Below is the complete question, it can be found elsewhere:
What is the probability of finding an electron within one Bohr radius of the nucleus?<span>Consider an electron within the 1s orbital of a hydrogen atom. The normalized probability of finding the electron within a sphere of a radius R centered at the nucleus is given by 1-a0^2[a0^2-e^(-2R/a0)(a0^2+2a0R+2R2)]. Where a0 is the Bohr radius (for a hydrogen atom, a0 = 0.529 Å.). What is the probability of finding an electron within one Bohr radius of the nucleus? What is the probability of finding an electron of the hydrogen atom within a 2.30a0 radius of the hydrogen nucleus?
Below is the answer:
