I see a pillow
But you see...this bobcat
Cute ain’t it?
P=change in E/t
Change in E=p*t
=15*3
=45
The answer is 45J.
Answer:
I know the first one is C.) 4J. I don't know of the answer for the second oneis suppose to be in N/m form? but I got
2,500N/m
One
d = 400 m
t = 20 s
speed = ?
speed = 400 / 20
speed = 20 meters/second
Two
d = 50 meters
t = 10 seconds
speed = 50 meters / 10 seconds
speed = 5 meters / second
The answer is C) C and E.
The wavelength, or the period of the wave, is the length or amount of time of one complete cycle, meaning the time it takes for the wave to return to its original position. A period involves one trough, one crest, and a return to rest, or the zero. We can see that this occurs between C and E.
Another way to look at it is the period of time, or length, before the wave returns to its original position. Where the measurement starts isn't really relevant, as long as the measurement is where the wave returns to that position.
