Answer:
The final velocity of the wooden block is equal to 
Explanation:
Given that mass of bullet =
Mass of wood = 
Initial velocity of bullet = 
Final velocity of bullet = 
Initial velocity of wood = o
Final velocity of wood = ![v_{w]](https://tex.z-dn.net/?f=v_%7Bw%5D)
Here momentum is conserved so initial momentum = final momentum
.
Upon substituting these values in above equation , we get
.
The answer is A.Yes
Explanation:
The amplitude of a wave is the height of a wave as measured from the highest point of the wave to the lowest on the wave.
That's called the "normal" to the surface at that point.
D) The speed of a wave slows as it travels at different speed in different media.
Answer:
75degree don't forget wind and gravity force pulling down
