Answer:
The difference in distance from the speakers is 5.2 - 3.5 = 1.7 m
The listener would be 1/2 wavelength out of phase with the speakers
1/2 y = 1.7 m where y is the wavelength
y = 3.4 m the required wavelength
f = v / y = 340 m/s / 3.4 m = 100 / sec lowest frequency
Earth is located in one of the spiral arms of the Milky Way (called the Orion Arm) which lies about two-thirds of the way out from the center of the Galaxy.
Answer:
4
Explanation:
For gases :
1. The motion of gases molecule is in random manner at the room temperature.
2.The distance between the gas molecule is more and that is why gas can be compress.
3.The attraction force between the gas molecule is negligible or we can say that there is no any force between the gas molecules.that is why gas can be filled in the container.But the motion of the gas molecule does not stop they are still moving inside the container but the space for movement become less.When a gas container heated then the container start to vibrate because the movement of the gas molecule.
So the option 4 is incorrect.
