Answer:
The frequency is the same
Explanation:
When a wave is created by a source which is vibrating at a certain frequency, the frequency of the wave itself is equal to the frequency of the source.
This occurs with every kind of wave. For instance, if we consider the radio waves produced by an antenna, the frequency of the radio waves is equal to the frequency of the antenna.
In this case, the waves are created by the vibrating bug. The bug is vibrating with a certain frequency 
: as a consequence, the frequency 
of the waves produced by the bug will be equal to the frequency of vibration of the bug:
.
In SI units, its acceleration is (the distance from A to C) / 32 m/s^2 .
Answer:
what are you saying man. They do provide structure.
Explanation:
temperature decreases at higher altitudes because as air rises the pressure decreases.
Answer:
The speed of the 270g cart after the collision is 0.68m/s
Explanation:
Mass of air track cart (m1) = 320g
Initial velocity (u1) = 1.25m/s
Mass of stationary cart (m2) = 270g
Velocity after collision (V) = m1u1/(m1+m2) = 320×1.25/(320+270) = 400/590 = 0.68m/s
