Answer:

The distance travelled on the freeway is 149.5 miles.

Explanation:

The school bus travels on the freeway at constant speed. According to the statement, we need to calculate the distance travelled by the vehicle by means of the following formula:

x = v\cdot t (1)

Where:

x - Traveled distance, in miles.

v - Speed, in miles per hour.

t - Time, in hours.

If we know that v = 65\,\frac{mi}{h} and t = 2.3\,h, then the distance travelled by the school bus is:

x = v\cdot t

x =  \left(65\,\frac{mi}{h} \right)\cdot (2.3\,h)

x = 149.5\,mi

The distance travelled on the freeway is 149.5 miles.

A wire of length 26.0 cm carrying a current of 5.77 mA is to be formed into a circular coil and placed in a uniform magnetic fie
Olin [163]

Answer:

The maximum torque is  \tau_{max} =  1.139 *10^{-7} \ N \cdot m

Explanation:

From the question we are told that

   The length of the wire is  l =  26.0 \ cm  =  0.26 \  m

     The current flowing through the wire is  I  = 5.77mA  =  5.77 *10^{-3} \ A

      The magnetic field is  B = 3.67 \ mT  =  3.67 *10^{-3 } T

         

The maximum torque is mathematically evaluated as

        \tau_{max} =   \mu B  

Where \mu  is the magnetic dipole moment which is mathematically represented as

        \mu  =  \frac{I l^2}{4 \pi n }

Where n is the number of turns which from the question is  1

    substituting values

       \mu  =  \frac{ 5.77 *10^{-3}  *  0.26^2}{4  * 3.142* 1 }

     \mu  =  3.10 4*  10^{-5}  A m^2

Now  

      \tau_{max} =  3.104 *10^{-5} * 3.67 *10^{-3}  

      \tau_{max} =  1.139 *10^{-7} \ N \cdot m

In an RL series circuit, an inductor of 3.54 H and a resistor of 7.76 Ω are connected to a 26.6 V battery. The switch of the cir
podryga [215]

Answer:

Energy stored in inductor will be 20.797 J

Explanation:

We have given inductance L = 3.54 H

And resistance R = 7.76 ohm

Battery voltage V = 26.6 VOLT

After very long time means at steady state inductor behaves as short circuit

So  current i=\frac{V}{R}=\frac{26.6}{7.76}=3.427Amp

Now energy stored in inductor E=\frac{1}{2}Li^2=\frac{1}{2}\times 3.54\times 3.427^2=20.797J

So energy stored in inductor will be 20.797 J
