It is a device that helps us identify what things are made out of. It takes the light and splits it up into its component colors.
Answer with Explanation:
We are given that
a.Length of segment,l=20 m
Magnetic force ,F=
Substitute the values
Hence, the magnetic force exert by each segment on the other=0.0119 N
b.We know that when current carrying in the wires are in same direction then the force will attract to each other.
Hence, the force will be attractive.

Answer:
A) As the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch
B) As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.
Explanation:
From Doppler effect, the closer the source of sound gets to the observer, the higher the frequency and in turn the higher the pitch.
Meanwhile, the farther a source goes from an observer, the lower the frequency of the sound and also the lower the pitch.
Thus, as the ambulance's siren moves toward a stationary hearer, the quality of sound will have a higher pitch.
As the ambulance's siren moves away from a stationary hearer, the quality of sound will have a lower pitch.
