What Makes Packaging Material Better - High Density or Low Density Material? why

Depends!

Explanation:

High density packaging material can cost more to use in the end when it comes to packing items with them because the air inside takes up space. Low density packaging is advantageous in that it costs what you might call "ground money" per unit. High density boxes are most often used for product placement, while low-density is most often used for clothing box filling.

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
