Answer:
D) All of these
Explanation:
The magnetic flux through a coil of wire is given by:
where
B is the intensity of the magnetic field
A is the area enclosed by the coil
is the angle between the direction of B and the normal to the area of the coil
Therefore, we see that the magnetic flux depends on all these quantities:
A) the magnetic field
B)the orientation of the field with respect to the region through which it passes
C)the area of a region through which magnetic field passes
So, the correct answer is
D) All of these
When it comes to wave behavior, there are parameters called wavelength and frequency. These two are related by speed of the radiowave. Radiowaves are electromagnetic waves which travels as fast as light. The wavelength is the distance while frequency is the reciprocal of time. When you multiply them both, you get the electromagnetic wave's speed. The equation is c = wavelength*frequency, where c is the speed of light equal to 3 x 10^8 m/s.
3 x10^8 m/s = wavelength/104.9 x 10^6 Hz (Hertz is 1/s)
wavelength = 2.86 meters
Answer:
E=26779230N/C(option 5)
Explanation:
Let Lamda be charge per lenght=73*10^-6c/m
Distance r=4.9cm =0.049m
Coulomb constant k=8.98755*10^9
But electric field is 2*k*lamda/r
E=(2*8.98755*10^9*73*10^-6)/0.049
E=26779230N/C
