In the following atomic model, where does the strong nuclear force happen?

A diagram of an atom has three rings, labeled from outside to inside A, B, and C. A and B each carry two electrons. Inside ring C are 4 protons and 5 neutrons.
outside A
between A and B
between B and C
inside C

i would say the answer is food.

hope this !

the answer is 3.1 his answer is wrong mines is right

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
