V = S/t
The time is in minutes, it needs to be converted to seconds, because the Velocity 8.1meters/second.
1 min -------- 60 secs
8.5 min -------- x secs
-> x = 8.5 . 60
-> x = 510secs
-> 8.1 = S/510
-> 510 x 8.1 = S
-> S = 4131 meters
<h2>Answer:</h2>
The correct answer is water vapor.
<h3>Explanation:</h3>
- In evaporation of water, particles with high kinetic energy tend to leave the water surface.
- Because high kinetic energy molecules move faster than others breaking bonds with other molecules.
- And escape the water to air in form of vapors.
- While the ice water contain molecules with low kinetic energy.
Answer:
f' = 3665.51 Hz
Explanation:
given,
speed of the hawk = 24.7 m/s
frequency of screech emitted by the hawk = 3400 Hz
speed of sound = 331 m/s
By Doppler's effect

f' is the frequency received by the mouse
v is the speed of the sound
v_s is the speed of the hawk
now,

f' = 1.078 x 3400
f' = 3665.51 Hz
The frequency received by the stationary mouse is equal to 3665.51 Hz
' C ' is the only correct statement on the list. We don't know anything about diagram-x or diagram-y because we can't see them.
