Here it is given that speed of migrating Robin is 12 m/s relative to air
so we can say that
North
so it will be
Let North direction is along Y axis and East direction is along X axis
also it is given that speed of air is 6.7 m/s relative to ground
now as we know by the concept of relative motion
now by rearranging the terms
now we need to find the speed of Robin which means we need to find the magnitude of its velocity which we found above
So here we will say
so the net speed of Robin with respect to ground will be 13.7 m/s
for a given type of wave in a given medium a larger frequency means a smaller wavelength
Explanation:
Given that,
Radius = 10.5 cm
Magnetic field = 0.117 T
Time = 0.243 s
After stretched, area is zero
(I). We need to calculate the magnetic flux through the loop before stretched
Using formula of magnetic flux
Where, B = magnetic field
r = radius
Put the value into the formula
(II). We need to calculate the magnetic flux through the loop after stretched
Here, A = 0
So, The magnetic flux through the loop after stretched is zero.
(III). We need to calculate the magnitude of the average induced electromotive force
Using formula of the induced electromotive force
Hence, This is the required solution.
