Out of the choices given, one thing that ocean waves and sound waves have in common are they are both mechanical waves. The correct answer is E.
Answer:
B. m^2
Explanation:
The unit would be m^2 because there are two m's so the result is m^2.

If there were 3 m's the result wouldve been m^3 and so on...
The partial pressure of nitrogen is about 584 mmHg.
Answer:
Explanation:
In Michelson interferometer , two light waves from different directions are made to overlap so that fringes are formed on the screen due to interference . In it, two monochromatic and coherent light are made to overlap which have some path difference or phase difference. They form dark and bright fringes .
Now when a match stick is lit in the path of a wave , the fringes will disappear and an general illumination will be observed on the screen as the light from the lit match stick will not be coherent . Incoherent light can not form stable fringes.
_ acceleration occurs when an object speeds up.
