Answer:
145 degree
Explanation:
We are given that
Magnetic field=B=2 T
Charge on particle,q=
Velocity, v=
Angle,
We have to find the direction of the force exerted on this particle by magnetic field with magnitude 2 T in the z direction.
Component of velocity along x- axis
Along y- axis
Hence, the direction of force =145 degree
Answer: Different vocal tract and harmonics
Explanation:
We are given that a small boy and a grown woman both speak at approximately the same pitch.
To distinguish between the two, we check their harmonics which is different for both of them owing to the different vocal tracts they have. Owing to different vocal tracts, they each produce different harmonic which is actually the multiple of frequency of the wave. Thus, we can make the determination using this.
