Answer:
22)convex
23)sun (sunlight reflect of the off the surface of the moon
24)because of the way the atmosphere interacts with sunlight
25) transparent : glass,contact lenses,water,air
translucent: wax paper, oil paper, thin sheets
opaque : plastic, wood, leather
26)when light react with opaque: none of it passes though
when it reacts with transparent : it passes through
when it react with translucent : only some of it passes through, the light does not pass directly through the material
Explanation:
24 blue light is scattered in all directions by the tiny molecules of air in earth's atmosphere
They speed up when they get hotter and they slow down when they get colder. I think
Answer is: 2. atomic number.
Atomic number is unique and defines an element. Atomic number (Z) is total number of protons in an atom.
For example, nitrogen atom (N-14) has 7 protons (p⁺), 7 electrons (e⁻) and 7 neutrons (n°). Protons (positive charge) and neutrons are in the nucleus of atom, electrons (negative charge) are bound to the nucleus in spherical shells. Nitrogen is an element with atomic number 7. Mass number (A) is the total number of protons and neutrons in a nucleus. Nitrogen mass number is 14 (A = p⁺ + n°; A = 14).
Add proton + neutrons = Mass 37
Proton is same as your atomic mass= 17
If you go on the periodic table look up 17 and it will give u the letter.
