The braided metal shield is very good at blocking electromagnetic signals from entering the cable and producing noise.
sladkih [1.3K]

This assertion is accurate; electromagnetic signals are effectively blocked from entering the cable and causing noise by the braided metal shield.

<h3>What is electromagnetic ?</h3>

The study of charge, its forces, and the fields that surround it is known as electromagnetic. Two components of the electromagnetic electric field are electricity and magnetism. In science, electromagnetism is just an interaction that takes place between charged particles. It is also the dominant force in interactions between atoms and molecules and is also the second-strongest of a four basic interaction, after the strong force.

<h3>How does electromagnetic work and what was its purpose?</h3>

Electromagnets are wire coils with electricity flowing through them. An electromagnet's wire coils act like magnets when an electric current flows through them because moving charges produce magnetic fields.

Consequently, electromagnetic governs much more than only electricity and magnetism. It is the force that holds oppositely charged electrons to oppositely charged atomic nuclei, allowing for the formation of stable atoms and the occurrence of chemistry, including the chemistry that gives rise to life.

What is de Broglie's hypothesis ? Make sure to be specific (qualitative and quantitative)
victus00 [196]

Answer and Explanation:

DE BROGLIE 'S HYPOTHESIS :

  • According to De broglie the matter have dual nature it can behave as particle as well as wave
  • According to this hypothesis all matter have wave like property and having wavelength.
  • The de broglie wavelength is given by \lambda =\frac{h}{P} here h is plank's constant and P is momentum
  • This hypothesis determines the probability of finding the object at a give point
