Explanation:
Got it right on edge, hope this helps :)
Answer: B
Longitudinal wave
Explanation:
Transverse waves have crests and troughs
Longitudinal waves have compressions and rarefactions. A compression is where the density of the wave medium is highest. While a rarefaction is where the density of the wave medium is lowest.
Since sound wave is a longitudinal wave. And longitudinal wave exists apart from sound, we can therefore conclude that it's a longitudinal wave in spring.
Answer:
15.5 seconds
Explanation:
Apply Newton's second law:
∑F = ma
-12500 + 9200 = (12000) a
a = -0.275 m/s²
v = at + v₀
0 = (-0.275) t + 4.25
t = 15.5 s
It takes the boat 15.5 seconds to stop.
Answer:
Explanation:
Potential energy is the energy stored within an object, due to the object's position, arrangement or state
Explanation:
It varies with altitude, but at sea level, it's 9.8 m/s².
