In the open ocean, the distance between wave
crests is 50 meters and the wave oscillates up and
down 0.16 times a second. This causes the wave
to pass a given point every 6.25 seconds.
What is the speed of this wave?
A 1.0 m/s
c. 39.1 m/s
B. 8.0 m/s
D. 312.5 m/s

B. 8.0m/s

Explanation:

Distance between waves = 50m

T = 6.25secs

Speed = 50m/6.25secs

= 8.0m/s

thermal energy is the answer

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
