Answer:
A) 0.50 mV
Explanation:
In this problem, we can think the wings of the bird as a metal rod moving across a magnetic field. So, and emf will be induced into the wings of the bird, according to the formula:
where
is the strength of the magnetic field
v = 13 m/s is the speed of the bird
L = 1.2 m is the wingspan of the bird
is the angle between the direction of motion and the direction of the magnetic field
Substituting numbers into the formula, we find
The ratio of the forces is 9.59×10^-4.
The transverse speed in terms of tension in the string (T) of the wave is,
ω/k=√T/μ
T=ω^2k$2μ
Substituting the values we get,
T=[(50.0rad/s)^2/(0.800m−1)^2]×(12.0×10−3kg/m)
≈46.9N
The ratio of the transverse force and the tension is,
F/T=0.045N/46.9N
≈9.59×10^-4
Hence, the ratio of the forces is 9.59×10^-4.
