If the wavelength of one wave is 0.25 meters, how many waves will be formed on a rope that is one meter long?
ikadub [295]
<h3><u>Answer;</u></h3>

4 waves

<h3><u>Explanation;</u></h3>

Wavelength of one wave = 0.25 meters

Length of the rope = 1 meter

Therefore;

Number of waves = Length of the rope/wavelength of one wave

                              = 1/0.25

                              = 4 waves

g A circular loop of wire with radius 3 m is flat on the xy plane in a magnetic field which is pointed in the z-direction and ha
Phantasy [73]

Answer:

emf=-0.035V

Explanation:

this problem can be solved with the Lenz's law:

emf=-\frac{\Delta \Phi_{B}}{\Delta t}

where PhiB is the magnetic flux. In this case we have

\Delta \Phi_{B}=B(A_1-A_2)

due to the magnetic field is constant. A is the area of the circular loop. Hence

\Delta \Phi_{B}=(5*10^{-3}T)(\pi(3m)^2-\pi(1.5m)^2)=0.106Tm^2

Finally

emf=-\frac{0.106Tm^2}{3s}=-0.035V

HOPE THIS HELPS!!
