At any given location and time of day, it might be true that a fence post is 4 feet high casts a shadow that is 6 feet long? what is the ratio of the height of the object to the length of the shadow?

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

my dear correct answer is option number 3

answer: the answer is   graph (a)
