Attached is the balanced chemical equation xx
Density = mass/volume
density = 81 grams/0.9 cubic centimetersdensity = 90 grams per cubic centimeter
The density of the sample is 90 grams per cubic centimeter.
The electromagnetic force is responsible for most of the interaction we see in our environment today. The EMF holds electrons in their orbit around the nucleus.
Factors that can affect a magnets strength include : heat, radiation, strong, electrical currents in close proximity of to the magnet
Answer:
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Given, Wavelength = 515 nm
Also, 1 m = 
nm
So,
Wavelength = 
m
Thus, Frequency is:
