Radio waves are what cell phone company rely on
Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction.
Answer:
Explanation:
Let the length of the string is L.
Let T be the tension in the string.
Resolve the components of T.
As the charge q is in equilibrium.
T Sinθ = Fe ..... (1)
T Cosθ = mg .......(2)
Divide equation (1) by equation (2), we get
tan θ = Fe / mg
As θ is very small, so tanθ and Sinθ is equal to θ.
The process in which water vapor and
carbon dioxide retain heat is called the greenhouse effect.
<span>There are many gases which causes greenhouse
effect like carbon dioxide, methane, nitrous oxide, fluorinated gases etc. These
gases trap the heat in the atmosphere, resulting the surface of earth to get
warm producing greenhouse effect.</span>
