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

A tiger runs one kilometer. The tiger does 15,000 J of work and has a total power output of 500 W. How many minutes does it take
defon
Power is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. <span>As is implied by the equation for </span>power<span>, a unit of </span>power <span>is equivalent to a unit of work divided by a unit of time. The formula would be as follows:

P = W/t 

We calculate as follows:

500 W = 15000 J / t
t = 30 s</span>

An engineer is designing a spring to be placed at the bottom of an elevator shaft. If the elevator cable should happen to break
mamaluj [8]

Answer:

Value that the spring constant k = 12Mg / h

Explanation:

According to 2nd law of Newton:

upward force of the spring= F

The weight of the elevator W = mg

            F = Mg = M(5g)

==> F =6Mg.

As the spring is compressed to its maximum distance ie s,the maximum upward acceleration comes just , Hence

  F =ks = 6Mg

==>   s = 6Mg/k

We have gravitational potential energy turning into elastic potential of the spring as the elevator starts at the top some distance h from the spring, and undergoes a total change in height equal to h + s, so:

            Mg(h+s) = 1/2ks2

And plugging in our expression for s:

         Mg(h+6Mg/k)= 1/2k(6Mg / k)2

          gh + 6M2g2/k = 1/2k(36M2g2 /k2)

        Mgh +6M2g2/k = 1/2k(36M2g2 /k2)

             gh + 6Mg2/k = 18Mg2 / k

                             gh = 12Mg2 / k

                               h = 12Mg / k

                               k = 12Mg / h
