A solenoid 50-cm long with a radius of 5.0 cm has 800 turns. You find that it carries a current of 10 A. The magnetic flux throu

ioda

Answer:

126 mWb

Explanation:

Given that:

length (L) = 50 cm = 0.5 m, radius (r) = 5 cm = 0.05 m, current (I) = 10 A, number of turns (N) = 800 turns.

We assume that the magnetic field in the solenoid is constant.

The magnetic flux is given as:

$\phi_m=NBAcos(\theta)\\Where\ B\ is\ the\ magnetic\ field\ density,A\ is \ the\ area.\\But\ B =\mu_onI.\ n \ is\ the\ number\ of\ turns\ per\ unit \ length=N/L\\Therefore,B=\frac{\mu_oNI}{L} \\substituting\ the\ value\ of\ B\ in\ the\ equation: \\\phi_m=\frac{NAcos(\theta)*\mu_oNI}{L} .\ But \ \theta=0,cos(\theta)=1\ and\ A=\pi r^2\\ \phi_m=\frac{N^2\pi r^2\mu_oI}{L} \\Substituting\ values:\\\phi_m=\frac{800^2*(\pi*0.05^2)*(4\pi*10^{-7})*10}{0.5}=0.126\ Wb=126\ mWb$

Based on the image, which is not a wavelength?

ki77a [65]

The distance that is not a wavelength in the image is C to E.

<h3>What is wavelength?</h3>

Wavelength is the distance between two successive crests or two successive trough or crest to trough.

It is also the distance over which the wave's shape repeats.

Based on the image, the following are wavelengths;

A to E, this is wavelength because it is between a crest and a trough.
B to F, this is wavelength because it is between two successive crest.
D to H, this is wavelength because it is between two successive trough.

Thus, the distance that is not a wavelength in the image is C to E.

A satellite orbiting Earth at a velocity of 3700 m/s collides with a piece of

Gekata [30.6K]

Answer: B

Explanation:

You can use the conservation of momentum, under the assumption that no mass was lost when the collision occurred. The initial momentum of the system must equal the final momentum of the system. Our system is the region including, and only including, the satellite and the space debris. Classical momentum is defined as the product of mass and velocity:

$p_i=p_f$
