What current is required in the windings of a long solenoid that has 420 turns uniformly distributed over a length of 0.575 m in

order to produce inside the solenoid a magnetic field of magnitude 4.22×10−5 T? The permeablity of free space is 1.25664 × 10 Tm/A.

Answer:

The current in the solenoid=0.463 Ampere

Explanation:

Given:

Number of turns , N=420

Length of the solenoid=0.575 m

Magnitude of Magnetic Field,B=4.22\times10^{-5}\ \rm T

We know that the magnitude of the magnetic Field inside the solenoid is

B=\mu_0 ni

Where

  • \mu_0 is the permeability of free space.
  • n is the number of turns per unit length
  • i is the current

According to question

B=\mu_0 ni\\\\4.22\times10^{-5}=1.24664\times10^{-7}\times \dfrac{420}{0.575}\times i\\=0.463\ \rm Amp

Hence the current is calculated.

Zinaida [17]

Answer:

Earth's gravity would increase with the increase in Earth's mass. The driver hits a bump and the gravell falls out, so that the mass of the truck is one half as large after hitting the bump.

Explanation:

hope this helps :)❤️

Suppose that 2 scientists use different measurement systems in their work. What problems might arise if they shared their data?
bixtya [17]
<span>In assumption that there were two scientists who used different measurement systems in their research. The problems that might arise if they shared their data is obviously and primarily error. Errors are recognized and one element in every measure, system and quantity. Error was already even present in the measurement system alone a scientist used and it will furthermore aggregate, when these two different scales are combined the more error escalates in the process. There are two types: random and systematic error.   </span>

How do i find the number of leptons in an atom??
Serjik [45]

Answer:

In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions.[1] Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.
