Two rings of radius 5 cm are 20 cm apart and concentric with a common horizontal axis The ring on the left carries a uniformly distributed charge of 34 nC and the ring on the right carries a uniformly distributed chargeof -35 nC. A. What is the electric field due to the right ring at a location midway between the two rings?
= < X, Y, Z > N/C
B. What is the electric field due to the left ring at a location midway between the two rings?
= < X, Y, Z > N/C
C. What is the net electric field at at a location midway between the two rings?
= < X, Y, Z > N/C
D. If a charge of -7 nC were placed midway between the rings, what would be the force exerted on this charge by the rings?
= < X, Y,Z> N

moisture is lackin, and organic acids are scarce.

1.   what is light?

light is an electromagnetic wave visible to the human eye. 

2. what is a reflection?

the rebounding of a light ray when it hits a mirror.

3. what is the incident ray?

contacts the surface of an object.

4. what is the reflected ray?

bounces off a reflective surface.

5. what is the normal ray?

perpendicular to the surface of a mirror.

6. what is the angle of incidence?

an angle formed by the incident ray and the normal.

7. what is the angle of reflection?

an angle formed by the reflected ray and the normal.

8. what is refraction?

(bending.)

9. what is a converging lens?

bring together light rays that pass through.

10. what is a diverging lens?

spreads out light passing through.

11. focal point?

the real point where the refracted rays meet when the incident rays run parallel.

i copy pasted btw from an website..

well, their are quite a few differences !

explanation:

first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.

a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
