Answer:
Approximately 13.4 meters per second (m/s)
Explanation:
We can divide the distance by 60 seconds to find the trains average rate of speed.
803.98 / 60 ≈ 13.4
Best of Luck!

Answer:
The speed of a spound wave in this water is 1484.1 m/s
Explanation:
Step 1: Data given
Frequency = 349.2 Hz
Wavelength = 4.25 m
Step 2: Calculate the speed
v = f*λ
⇒ with v= the speed of a sound wave in this water
⇒ with f = the frequency = 349.2 Hz
⇒ with λ = the wavelength = 4.25 m
v = 349.2 Hz * 4.25 m = 1484.1 m/s
The speed of a spound wave in this water is 1484.1 m/s
Nitrogen is a gas because it is an airlike fluid substance which expands freely to fill any space available, irrespective of it's quantity
The answer is B. Because reactions are what goes in. Products are what comes out
