Do u have to find z? how do yk what z is?
Answer:
v = a/√(2h/g) m/s
Explanation:
Lets say the distance away from the cliff is a.
then, a = v t
where v is velocity with which it was thrown and t is time taken to fall.
Using equations of motion, we can also say that
h=1/2gt^2
where h is the height of the cliff
Thus, t^2 = 2h/g and t = √(2h/g)
Thus, v = a/√(2h/g).
the vehicle was pushed off the cliff with the velocity , v = a/√(2h/g). m/s
The inner core is composed of the earth's crust and solid upper mantle.
Acoustic Energy
Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects
Answer:
192 mm/s
Explanation:
The frequency, speed and wavelength of any given wave are related to one another by the formula;
fλ = v
Where f denotes the frequency, v the speed or velocity and λ the wavelength
We are given that;
λ = 12
f = 16
v = 16 * 12 = 192 mm/s
