A long hollow cylindrical conductor (inner radius = 2.0 mm, outer radius = 4.0 mm) carries a current of 12 a distributed uniform
11Alexandr11 [23.1K]

Here we can use ampere'a law to find the magnetic field

\int B.dl = \mu_o i_{en}

B*2 \pi r = \mu_o (i_1 + \frac{i_2*\pi(3^2 - 2^2)}{\pi(4^2 - 2^2}

B*2 \pi*0.003 = 4\pi * 10^{-7} (12 + 5)

B = 4\pi * 10^{-7} (12 + 5)

B = 1.13 * 10^{-3} T

Which shows the correct angle of reflection given the incident ray shown? <br>​
kipiarov [429]

\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the Rays of light.

Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.

Thus Option c.) is correct.

C.) is the Answer.

A 1.6-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. The spring has an
romanna [79]

Answer:

k = 652 lb/ft

Explanation:

Given :

Weight of the collar = 1.6 lb

The upstretched length of the spring = 6 in

Speed  = 16 ft/s

PA = 8 + 10

     = 18 inch

Let the initial elongation be $\Delta x_i$

∴ $\Delta x_i$ = 18 - 6

         = 12 inch = 1 foot

$PB = \sqrt{13^2+5^2}$

      = 13.925 inch

Final elongation in the spring

$\Delta x_B = 7.928 $ inch = 0.66 feet

Applying the conservation of the mechanical energy between A and B is

$K.E_A+P.E_{g,A}+P.E_{sp,A}= K.E_B+P.E_{g,B}+P.E_{sp,B} $

$0+mg_r+\frac{1}{2}k(\Delta x_i)^2=\frac{1}{2}mv_B^2+0+\frac{1}{2}k(\Delta x_B)^2$

$\frac{1}{2}k[(1)^2-(0.66)^2]=\frac{1.6}{2}\times (16)^2-1.6 \times 32 \times \frac{5}{12}$

0.281 \ k =204.8-21.33

k = 652 lb/ft
