Aplanar loop consisting of four turns of wire, each of which encloses 200 cm2, is oriented perpendicularly to a magnetic field that increases uniformly in magnitude from 10 mt to 25 mt in a time of 5.0 ms. what is the resulting induced current in the coil if the resistance of the coil is 5.0 ?

0.6A

Explanation:

Area of loop =200cm2 =200 x10 ∧-4m∧2  Change in Magnetic field (B)= 25mT -10mT =15mT time =5ms

From Faraday' s law of induction EMF(E)= change in magnetic field/time

    E= 15mT/5ms

Note, that one weber per second is equivalent to one volt.

= 3V

from Ohm's law I =E/R  

=3/5 =0.6A

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

answer: (431,2)
