The answer is B.) hope this helps
It depends. If you are driving and the person doesn't look like a serial killer, you should stop.
Answer:
A
Explanation:
the horizontal and vertical force acting on it consist a net force on the inclined direction (30degrees below the horizontal) you can tell by the length of the horizontal component (try to see the 30degree incline as horizontal, because that's the direction of the displacement). net work done on the system results in an increase in energy. i hope this can help :D, i'm also taking the ap physics 1 exam tommorow.
"Wavelength" is the distance between two crests or two Troughs.
It is the <span>distance between compressions or the distance between rarefactions on a longitudinal wave too!
So, your final answer is "Wavelength".
Hope this helps!!</span>
