A solenoidal coil with 25 turns of wire is wound tightly around another coil with 300 turns. The inner solenoid is 25.0 cm long
joja [24]

Answer:

5.65487\times 10^{-8}\ Wb

1.17\times 10^{-5}\ H

-0.020475 V

Explanation:

\mu_0 = Vacuum permeability = 4\pi \times 10^{-7}\ H/m

N_1 = Number of turns of coil  = 25

N_2 = Number of turns of coil 2 = 300

\frac{di_2}{dt} = Rate of current increased = 1.75\times 10^3\ A/s

d = Diameter = 2 cm

r = Radius = \frac{d}{2}=\frac{2}{2}=1\ cm

A = Area = \pi r^2

Magnetic field in the solenoid is given by

B=\mu_0\frac{N_2}{l}I\\\Rightarrow B=4\pi\times 10^{-7}\frac{300}{0.25}\times 0.12\\\Rightarrow B=0.00018\ T

Magnetic flux is given by

\phi=BA\\\Rightarrow \phi=0.00018\times \pi\times 0.01^2\\\Rightarrow \phi=5.65487\times 10^{-8}\ Wb

The average magnetic flux through each turn of the inner solenoid is 5.65487\times 10^{-8}\ Wb

Mutual inductance is given by

L=\frac{N_1\phi}{i_1}\\\Rightarrow L=\frac{25\times 5.65487\times 10^{-8}}{0.12}\\\Rightarrow L=1.17\times 10^{-5}\ H

The mutual inductance of the two solenoids is 1.17\times 10^{-5}\ H

Induced emf is given by

V=-L\frac{di_2}{dt}\\\Rightarrow V=-1.17\times 10^{-5}\times 1.75\times 10^3\\\Rightarrow V=-0.020475\ V

The emf induced in the outer solenoid by the changing current in the inner solenoid is -0.020475 V

during a space shuttle launch about 830,000 kg of fuel is burned in 8 min. the fuel provides the shuttle with a constant thrust,
kirill115 [55]
The shuttles acceleration in the creases as the fuel is burned because the acceleration of the obect as produced by net force is directly proportional to the magnitude of the net force.

What is the lewis structure of the covalent compound that contains one nitrogen atom
mario62 [17]

Full Question:

What is the Lewis structure of the covalent compound that contains one nitrogen atom, one hydrogen atom, and one carbon atom?

Explanation:

This covalent compound is the hydrogen cyanide, HCN.

The following steps are used to obtain it;

Step 1. Draw a skeleton structure of the compound based on the elements

Put the least electronegative atom C in the middle with H and Cl on either side.

H-C-N

Step 2. Count the valence (outermost) electrons you can use

H + C + N = 1 + 4 + 5 = 10

Step 3. Add these electrons to give every atom an octet

You have to put a triple bond between C and N.

Note: Each bond is made up of two electrons.

The lewis structure is given in the image below;
