The word that best fits is frequency. The sentence is The frequency of a wave is a measure of the amount of energy it carries. There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h * frequency. So, the answer is frequency.<span> Although you should know that wavelength is related to frequency and so it is also a measure of the amount of energy and it should also be other valid answer.</span>
Concentration can be measured in ppm. ppm means parts mer million. In terms of mass , ppm units are mg/kg.
concentration of AgCl solution is the mass of AgCl solute in mg per 1 kg of solution.
mass of AgCl present = 1.2 x 10⁻³ kg = 1.2 mg
mass of solution = 800 g = 0.800 kg
the mass of AgCl in 0.800 kg of solution = 1.2 mg
therefore mass of AgCl in 1 kg of solution = 1.2 mg / 0.800 kg x 1 kg = 1.5 mg
concentration of AgCl is 1.5 mg/kg
since mg/kg = ppm
concentration of AgCl = 1.5 ppm
answer is 1.5 ppm
A) mass of solute = 17 g
mass of solvent = 183 g
% = mass of solute / total x 100
% = 17 / ( 17 + 183 ) x 100
% = ( 17 / 200 ) x 100
% = 0.085 x 100
= 8.5 %
________________________________
b) mass of solute = 30.0 g
mass of solvent =300.0 g
% = mass of solute / total x 100
% = 30.0 / ( 30.0 + 300.0 ) x 100
% = (30.0 / 330.0 ) x 100
% = 0.090 x 100
<span>= 9.0 %

Explanation:
Answer:
Scopolamine.
Explanation:
Scopolamine is also known as hyoscine. It is an anticholinergic, oral topical drug which is used to manage, and prevent motion sickness, and acute treatment. It is must be taken to be effective before the onset of motion sickness.
The scopolamine is helps to prevent communication between the vomiting center which is present in the brain, and the nerve of the vestibule by blocking the action of acetylcholine (it is a chemical which nervous used to transmit massage to each other).
