Answer:
0.3405V
Explanation:
#Given a magnetic field of
, diameter= 18.5cm(r=9.25cm or 0.0925m), we find the magnetic flux of the loop as:

we can now calculate the induced emf,
:

Hence, the induced emf of the loop is 0.3405V
Answer:
The velocity of wind with respect to cyclist is
.
Explanation:
speed of cyclist = 12 km/h east
speed of wind = 5 km/h south west
Write the speeds in the vector form

The velocity of wind with respect to cyclist is

Answer:

Explanation:
We are going to use the accelerated motion formula
on the vertical component taking the upwards direction as positive.
Since <em>at maximum height the speed will be
</em>, the formula can be written as
, which for our values is:

Written to three decimal places.
