A snowboarder whose initial speed is 6 m/s increases her speed to 8 m/s in order to win a race. If the boarder takes 4.0 s to complete this increase in her speed, what is her acceleration?

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

the index of refraction of the second medium is higher. i just took the test trust me !

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
