I would say the last one because unlike beta and alpha rays they will have no effect on the mass or atomic number because they are just composed of high energy radiation

Answer:

have no effect on atomic number or mass number of the atoms that emit them.

Explanation:

  • Unlike alpha and beta particles gamma rays are weightless packets of energy which have both mass and energy. Gamma rays are more like visible light but they have much higher energy. Based on this option D is true because gamma rays have no mass that is why they have no effect on atomic number of the atoms that emit them.

The plunger on a bicycle pump with a 400 mL volume cylinder is
Kobotan [32]

Answer:

The answer to your question is V2 = 66.7 ml

Explanation:

Data

Volume 1 = V1 = 400 ml

Pressure 1 = P1 = 1 atm

Volume 2 = V2 = ?

Pressure 2 = P2 = 6 atm

Process

1.- To solve this problem use Boyle's law

                     P1V1 = P2V2

-solve for V2

                     V2 = P1V1 / P2

-Substitution

                      V2 = (1)(400) / 6

-Simplification

                      V2 = 400 / 6

-Result

                      V2 = 66.7 ml

PLS HELP ASAP!!!! Describe metallic bonds, include an explanation of their valence electrons. How this related to the properties
Aloiza [94]

If you look it up it will give you plenty of information. This is what I found:

The valence electrons of metals move freely in this way because metals have relatively low electronegativity, or attraction to electrons. The positive metal ions form a lattice-like structure held together by all the metallic bonds. ... When nonmetals bond together, the atoms share valence electrons and do not become ions
