Two waves are superposed. One wave has an amplitude of 3 cm, and the other has an amplitude of 4 cm. What is the resultant amplitude?

Answers

Answer 1

Answer: The sum (or difference) of two solutions of the wave equation is again a solution of the wave equation(superposition principle)

therefore the amplitude of resultant wave is 3+4= 7cm

Answer 2

Answer:

Answer:

7 cm

Explanation:

When the waves are super-posed their amplitudes are added algebraically to get the resultant amplitude.

resultant amplitude = 3+4 = 7cm

Hydrogen has three isotopes 1H, 2H, and 3H. What is the difference between these three isotopes?

Answers

The element Hydrogen has three isotopes. The hydrogen (1H), the deuterium (2H), and tritium (3H) differs in number of their neutrons where hydrogen has none while deuterium has one and tritium has two. They also differ in mass numbers where hydrogen has one while deuterium has two and tritium has three.

Its just that the number of neutrons range from 0 to 2. (distance from 1 to 3 is 2)

Measuring the amount of deuterium in the universe allows us to set a limit on _________.

Answers

Answer:

the density of ordinary (baryonic) matter in the universe

Explanation:

Deuterium detection is of interest because the amount of it may be related to the amount of dark matter in the universe, but precise measurements have been difficult to obtain. Due to the way in which deuterium was created in the Big Bang, an exact measurement of the amount of deuterium would allow scientists to set limits on the models of the great explosion.

Also, an exact measure of deuterium would be an indicator of the cosmic density of barions (ordinary matter), and that density of barions would indicate whether ordinary matter is dark and is found in regions such as black holes, gas clouds or brown dwarfs, or it is bright and can be found in the stars. This information will help scientists who try to understand the very beginning of our universe.
