In science i really need answers in the book for my assignments.
1) which is neutral? neutron, proton, both a & b, or neither a nor b
2) it is a basis for an atom's individuality? neutron, proton, both a or b, or neither a nor b
3) it is responsible for the mass of an atom? nuetron, proton, both a or b, or neither a nor b

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
