Answer:
Explanation:
#Consider a circular area of radius in the xy-plane at z=0. This means all the are vector points toward the +ve z-axis.
a. first, find the magnetic flux if the magnetic field has a magnitude of and points toward the +ve z-axis. The angle between the magnetic field and the area is
. Hence the magnetic flux:-
Hence flux magnitude in direction is
b. We now find the magnetic flux when the field has a magnitude of <em>B=0.230T</em> and points at an angle of from the
direction.
Magnetic flux is calculated as:
Hence the flux at an angle of is
c. We now need to find the magnetic flux if the field has a magnitue of B=0.230T and points in the direction of +y-direction. As with the previous parts, the magnetic flux will be calculated as:
Hence the magnetic flux in the +y-direction is zero.
Answer:
Explanation:
= v/f
^That is the formula we are going to use.
Now, we were given the speed (v), which is 20.
Now we need to find frequency, in order to solve for the wavelength.
Frequency is the amount of waves in a fixed unit of one second, meaning our F value is the value of 5 divided by 4.
5/4 = 1.25
Therefore our F is 1.25
Now lets plug it in
= v/f
= 20/1.25
= 16
Conversion:
= 8
