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)
The deep the probe goes, the lower the temperature becomes. Therefore, the probe will record temperature lower than 3°C. The figure attached shows the relationship between temperature and depth of water.
Answer:
Explanation:
Ptolemy and Copernicus have presented different model in front of us.
As per Ptolemy, Earth is the center of the universe and all other planets and celestial bodies such as moon or Sun revolve around it. So as per his theory he would say that the celestial would rotate in west side due to which Sun would appear in eastern horizon.
But Copernicus theory is a contradiction of Ptolemy's work. As per him, Sun is the center of the universe and all other planets revolve around it. For the Sun rise event, he would have said the Earth rotates at east side and Sun appears.
The answer is B hope I helped
