Answer:
1Kilowatt =1000watts
Now
Energy =Power x time
We need our power in Kilowatt and Our time in hours
Given
Power = 1200Watt
Divide this by 1000... To get its value in Kilowatt
Power = 1.2kilowatt
Time=6min
Divide by 60 to get its value in hours
Time = 6/60hr = 0.1hrs
Energy = 1.2kilowatt x 0.1hrs
=0.12kilowatt hours
Answer:
![6.3\cdot 10^{-4} V](https://tex.z-dn.net/?f=6.3%5Ccdot%2010%5E%7B-4%7D%20V)
Explanation:
According to Faraday-Newmann-Lenz, the induced emf in the loop is given by:
(1)
where
is the rate of variation of the magnetic flux through the loop.
We know that the magnetic flux through the loop is given by
![\Phi = BA](https://tex.z-dn.net/?f=%5CPhi%20%3D%20BA)
where B is the magnetic field and A is the area of the loop. Since the magnetic field is constant, we can write the variation of flux as
![\Delta \Phi = B \Delta A](https://tex.z-dn.net/?f=%5CDelta%20%5CPhi%20%3D%20B%20%5CDelta%20A)
So eq.(1) becomes
![\epsilon=-B\frac{\Delta A}{\Delta t}](https://tex.z-dn.net/?f=%5Cepsilon%3D-B%5Cfrac%7B%5CDelta%20A%7D%7B%5CDelta%20t%7D)
and the problem gives us:
is the magnetic field
is the rate at which the area changes
Substituting into the equation, we find
![\epsilon=-(0.50 T)(-1.26\cdot 10^{-3} m^2/s)=6.3\cdot 10^{-4} V=0.63 mV](https://tex.z-dn.net/?f=%5Cepsilon%3D-%280.50%20T%29%28-1.26%5Ccdot%2010%5E%7B-3%7D%20m%5E2%2Fs%29%3D6.3%5Ccdot%2010%5E%7B-4%7D%20V%3D0.63%20mV)
