The pressure p (in pounds per square foot), in a pipe varies over time. ten times an hour, the pressure oscillates from a low of 60 to a high of 300 and then back to a low of 60. the pressure at time t=0 is 60. let the function p=f(t) denote the pressure in pipe at time t minutes. find a possible formula for the function p=f(t) described above.

step-by-step explanation:

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.
