D.
The reading between 7N and 8N would have to be 7.5N. Answers A and B are much to small and answer C is way to big.
Answer:
Sound wave types - longitudinal waves
Longitudinal waves - Vibrating string the creates sound in the way it moves.
Explanation:
Longitudinal waves have particles of the medium that are displaced in a parallel direction to energy transport.
Answer:
Explanation:
The path length difference = extra distance traveled
The destructive interference condition is:

where m =0,1, 2,3........
So, ←

⇒ λ = 2Δd = 2×10 = 20
Answer:
2.1km
Explanation:
Ill take it as u are talking about the displacement
Since displacement has negatives and positves
5.9 - 3.8 = 2.1km
... the density of the liquid
... the volume of the submerged object
