How does running an electric current through wire cause a magnetic field?

Engineering

Eva8 [605]3 years ago
3 0

Answer:

When a charged particle—such as an electron, proton or ion—is in motion, magnetic lines of force rotate around the particle. Since electrical current moving through a wire consists of electrons in motion, there is a magnetic field around the wire.

Let CFG G be the following grammar.
adoni [48]

Answer:

See Explanation Below

Explanation:

Given

S → aSb | bY | Y a

Y → bY | aY | ε

Giving a simple description of L(G) in English. The description is as follows;

This means that L(G) contains a string of a's and b's such that the following are true;

1. the string starts with n a’s and m b’s, where n and m can be zero, but not at the same time,and at least one of option 2 and option 3

2. and has any number of a’s or b’s followed by an a

3. ab followed by any number of a’s and b’s

Note that n and m represent numerical digits

Using the description to give a CFG for L(G), the complement of L(G) is written as L'(G)

L'G are elements not in L(G) and they are

L'(G) =a^n b (a∪b) * b^n ∪ a^n (a∪b) * ab^n

A mass of 0.3 kg is suspended from a spring of stiffness 0.4 N/mm. The damping is 3.286335345 kg/s. What is the undamped natural
mina [271]

Answer:

 f=5.81 Hz

Explanation:

Given that

m= 0.3 kg

K= 0.4 N/mm

K= 400 N/m

C= 3.28

We know that undamped natural frequency given as

\omega= \sqrt{\dfrac{K}{m}}

Now by putting the values

\omega= \sqrt{\dfrac{K}{m}}

\omega= \sqrt{\dfrac{400}{0.3}}

  ω = 36.51 rad/s

We know that

ω = 2 π f

36.51 = 2 x π x f

f=5.81 Hz

So the undamped natural frequency is 5.81 Hz.
