If the refractive index of some substance is  1.33, then
the speed of light in that substance is
                  
               (speed of light in vacuum) / (1.33)  = 

                         (299,792,458 m/s) / (1.33)  =  <em>225,407,863 m/s</em>

v=2.25` 10^{8}  \frac{m}{s}
N=1.33 being the Index of Refraction of a material and c=3.0` 10^{8}  \frac{m}{s} the speed of light in vacuum you get:
v= \frac{c}{N}= \frac{3.0 10^{8} }{1.33}=2.25` 10^{8}  \frac{m}{s} speed of light in that material.

Which particles contribute to the net charge and how does each change the net charge?
Licemer1 [7]

The two subatomic particles that contribute to the net charge of an ion are electrons and protons.

<h3>What is an atom?</h3>

Atom is the smallest possible amount of matter which still retains its identity as a chemical element, now known to consist of a nucleus surrounded by electrons.

The atom is made up of three components called subatomic particles as follows;

  • Protons
  • Electrons
  • Neutrons

The proton is the positively charged subatomic particle forming part of the nucleus of an atomwhile the electron is the subatomic particle having a negative charge and orbiting the nucleus.

This suggests that the two subatomic particles that contribute to the net charge of an ion are electrons and protons. That is;

Net charge = protons - electrons

According to the graph above, how large of a force is needed in order to stretch the string 1.00 meters?
gulaghasi [49]

My guess for this one would be; 400 N

My reasoning would be; it starts at 0 on both X and Y, if you need to get to 1.00 meters thats 4/4. 1/4 of 1.00 is .25, and on .25 its on 100 so multiply it by 4 to make 1.00 and you get 400 N
