H would be the correct answer senate house of rep then congress then president to sign
Velocity is the displacement of an object over the amount of time. It is not the same as speed. If an object travels 4 miles forward and then 4 miles back all in one hour, its speed is 8 mph. However, displacement is the difference between the final position and the initial position. So in this case, the average velocity would be 0 because its final and initial positions were the same.
wavelength =wavevelocity
--——————
Frequency
Frequency = 1/T => 1 / 6.73 = 0.1486
Wave velocity = L/T => 3.75 / 6.73 = 0.5572
Therefore, wave length = 0.5572/0.1486 = 3.75m
Fusion,melting,vaporization,submlimination are examples of endothermic changes
