Answer:
When two waves meet in such a way that their crests line up together, then it's called constructive interference. The resulting wave has a higher amplitude. In destructive interference, the crest of one wave meets the trough of another, and the result is a lower total amplitude.
Hi, here is the first part of the answer..do you know what type of graph it's wanting?? (line graph, bar graph, ect.)
Answer:
Answer to #1, is D.
Explanation:
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. This is also, a theory with the ring of fire.
Answer:
fundamental frequency= 20Hz
length= 4.3m
Explanation:
resonating frequencies = 60 Hz,100 Hz,140 Hz
speed of sound =344 m/s
as well behaves as organ pipe with are end closed
only odd harmonics are allowed
, so the vibration will corresponds to n=1,3,5,7....
(2n−1) λ
/4 = l (∵λ
= V/f)
(2n-1) V / 4f = l
(2m-1)/6= (2n-1)/10= (2p-1)/14 =A
The given frequencies happen to be 3rd,5th & 7th harmonics of the fundamental frequency n=20Hz.
Therefore, The fundamental frequency will be 20 Hz because 60 Hz is corresponding 3rd harmonic
In order to find length,
(2n-1) V / 4f = l
= 4.3m
therefore, the well is 4.3m deep
Answer:
0.241
Explanation:
resolving weight into two components and calculating force of friction in terms of coefficient of friction and then applying Newton 's law we get the value .This all has been explained in attachment
