Answer:
25° F
Explanation:
3,000 = 6,000
=> Temperature at 3,000 feet above sea level = Temperature at 6,000 feet above sea level = 50° F = 25° F
B.false.
It's more likely our solar system exist in the "suburbs" of the milky way.
Brahmins were considered the highest caste because they held the most power in Hindu society. This was becuase they were priests which was otherwise known as the spiritual and intellectual leaders of the society.
C) the wavelength increases / lower pitch
Explanation:
As the train passes away from the observer at a point, the wavelength of the sound wave will increase and the pitch will become lower.
This phenomenon is known as the Doppler's effect.
The Doppler effect is the change in frequency of wave relative to an observer's position.
- The observer will hear the greatest sound when the train is at a very close proximity to him.
- The farther the separation between the observer, the lower the sound he hears.
- This implies that the pitch of the sound will decrease as the train moves away.
- The wave frequency has reduced due to an increase in the wavelength.
