Two coils are wound around the same cylindrical form. when the current in the first coil is decreasing at a rate of -0.245 a/s , the induced emf in the second coil has a magnitude of 1.60×10−3 v .part apart completewhat is the mutual inductance of the pair of coils? mm= 6.53×10−3 hprevious answerscorrectpart bpart completeif the second coil has 20 turns, what is the flux through each turn when the current in the first coil equals 1.25 a ? φφ= 4.08×10−4 wbprevious answerscorrect

Complete question:

c.If the current in the second coil increases at a rate of 0.365 A/s , what is the magnitude of the induced emf in the first coil?

a.

b.flux through each turn = Ф =

c.magnitude of the induced emf in the first coil = e=

Explanation:

a. rate of current changing = " alt="M=\frac{1.60\times10^{-3} V}{0.240\frac{A}{s} }}" />" />

  Induced emf in the coil =e=

  For mutual inductance in which change in flux in one coil induces emf in the second coil given by the farmula based on farady law

b.

  Flux through each turn=?

  Current in the first coil =1.25 A

   Number of turns = 20

       using   MI = NФ

     flux through each turn = Ф =  

   flux through each turn = Ф =

c.

   second coil increase at a rate = 0.365 A/s

  magnitude of the induced emf in the first coil =?

 using  

magnitude of the induced emf in the first coil = e=

carbon is found in all living things. carbon atoms move constantly through

living organisms, the oceans, the atmosphere, and the earth’s crust in what is

known as the carbon cycle. the directions taken by carbon atoms through this

cycle are very complicated and can take millions of years to make a full circle.

all animals, from humans to the dinosaurs are part of the carbon cycle. when

animals eat food, they get carbon in the form of carbohydrates and proteins.

in animals, oxygen combines with food in the cells to produce energy for daily

activity and then gives off carbon. the carbon combines with oxygen to form

carbon dioxide (co2) and is released back into the atmosphere as a waste

product when animals breathe and exhale.

from 145-65 million years ago, earth was much

hotter than today and covered with dense,

tropical swamp forests. the trees and other

plants were immense and

provided an endless supply of

food for the giant animals that

roamed the land. somewhere in

the air above one of these

forests, a lone carbon atom has joined

up with two oxygen atoms to form a molecule of co2.

the co2 molecule was sucked into the tiny holes (stomata) on the leaf of a

fern plant and joined with sunlight, chlorophyll and water to make food and

energy in the plant’s cells through photosynthesis. the oxygen (o2) from the

co2 molecule was sent back into the atmosphere; the carbon atom (c) was

detached and used to make a molecule of sugar.

if that carbon atom had been eaten instead, a totally

different situation would have developed. let’s say

that a giant plant-eating dinosaur (herbivore) ate the

fern for breakfast, and swallowed the carbon in the

fern in the form of carbohydrates and proteins. in

the process of respiration, oxygen combined with

the carbohydrates and proteins in the dinosaur’s cells

to provide energy for its daily activity.
