A wave transfers energy from the source outward in the
direction of wave motion.

Answer:
V = 38.582 m/s
Explanation:
Initial Vertical Velocity = 0
Let's use the motion equation given below to solve for the final vertical velocity:

Here a = 9.81 m/s^2
and s = 30 m
Solving for v, we get:
v = 24.261 m/s
This is just the vertical velocity, to get the total velocity we need to add the horizontal component of velocity with this:
Total velocity = Sqrt ( Horizontal Velocity^2 + Vertical Velocity^2)

where
and 
V = 38.582 m/s
The characteristic of life would be homeostasis. Homeostasis regulates the variables in which internal conditions remain stable and consistent. This type of regulation is the regulation of temperature and the balance between acidity and alkalinity, also known as pH. Hope this helps! :)
