In longitudinal waves, the motion of the particles in a medium is across the direction of the wave.
A graph of acceleration would have to be a graph with an increasing slope, since you're going faster and faster
a graph of deceleration would have to be a graph with a negative slope since you are slowing down over time
Answer:
Explanation:
Given
initial velocity 
Distance traveled before stopping 
using equation of
where v=final velocity
u=initial Velocity
a=acceleration
s=displacement
v=0 as car stops after travelling 
negative sign indicates it is deceleration
Answer:
d
Explanation:
the dendrites is a part of the neuron receives messages from other neurons. Dendrites extend out from the cell body and receive messages from other nerve cells
This is the Doppler effect.
1. As the sound leaves the horn the sound waves are at first close to each other and as they move outwards they become further apart. The closer the sound waves are the louder the noise.
As the car gets the closer the sound waves get closer, so the horn becomes louder.
2. As the horn moves away, the sound waves become less frequent, causing the pitch to get lower.
