The right answer for the question that is being asked and shown above is that: "A crest with an amplitude of 9 will form." Wave X has an amplitude of 5 and wave Y has an amplitude of 4. the crest of wave X meets the crest of wave Y is that <span>A crest with an amplitude of 9 will form.</span>
Answer: H
Explanation:
When beavers dam a stream they slow the movement of water. Behind the beaver dam, a pond of still water is formed. This pond is then colonized by animals and plants that typically live in lakes rather than streams.
Answer: (2) 108 C
Explanation:
Electric charge of 1 coulomb has said to have passed when a current of 1 Ampere is passed for 1 second.
Q= charge in coloumb = ?
I = current in amperes = 0.120 A
t= time in seconds = 900 sec
Speed of the black Mamba = 18 km/h = 5m/s
now the distance that black mamba cover to catch prey
Now it returns to its hide in 12 s
so average speed of return is given as
Part b)
For the whole trip we know that displacement of the mamba is zero
so average velocity of whole trip will be zero
Part c)
For average speed we know that total distance of the black mamba
d = 12.5 + 12.5 = 25 m
total time taken = 2.5 + 12 = 14.5 s
now average speed is given as
It’s true because it doesn’t did use time in interval
