Awave has a wavelength of 7 mm and a frequency of 13 hertz. what is its speed?

0.091 m/s

Explanation:

Given in the question that,

wavelength of a wave = 7mm

frequency of a wave = 13 hertz

Formula to use

here f = frequency in hertz

        v = velocity in m/s

        λ = wavelength in m

1 mm = 1x10

7mm = 7x10

Plug values in the formula

 13 = v / 7x10

  v =   13(7x10^{-3})

  v = 0.091 m/s

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.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
