pls mark me brainliest its the right answer
On the floor because the force from the train moving and she wouldn't be able to catch it in time
Give that,
The frequency range the dog can hear is 15Hz to 50,000Hz
The wavelength of sound in air at 20°C =?
Speed of sound is 344
The frequency corresponding to the lower cut-off point is the lowest frequency which his 15Hz
F=15Hz
The relationship between the wavelength, speed and frequency is given as
v=fλ
Then,
λ=v/f
λ=v/f
λ=344/15
λ=22.93m
Answer:
49 m/s
Explanation:
Acceleration = velocity / time
You should know accleration due to gravity is 9.8 m/s^2 and you're given t = 5, so you can solve for velocity:
9.8 = v / 5
v = 49
