Answer:
The lowest possible frequency of sound is 971.4 Hz.
Explanation:
Given that,
Distance between loudspeakers = 2.00 m
Height = 5.50 m
Sound speed = 340 m/s
We need to calculate the distance
Using Pythagorean theorem
We need to calculate the path difference
Using formula of path difference
Put the value into the formula
We need to calculate the lowest possible frequency of sound
Using formula of frequency
Put the value into the formula
Hence, The lowest possible frequency of sound is 971.4 Hz.
Answer:
(A). The speed of the ions is
(B). The radius of curvature of a singly charged lithium ion is
Explanation:
Given that,
Electric field = 60000 N/C
Magnetic field = 0.0500 T
(A). We need to calculate the velocity
For no deflection
(B). We need to calculate the radius
Using magnetic force balance by centripetal force
Put the value into the formula
Hence, (A). The speed of the ions is
(B). The radius of curvature of a singly charged lithium ion is
