Answer:
EMF = 187.5 volts
Explanation:
As per Faraday's law of electromagnetic induction we know that rate of change in the flux will induce EMF
so we can say
![EMF = -\frac{d\phi}{dt}](https://tex.z-dn.net/?f=EMF%20%3D%20-%5Cfrac%7Bd%5Cphi%7D%7Bdt%7D)
![EMF = \frac{\phi_i - \phi_f}{\Delta t}](https://tex.z-dn.net/?f=EMF%20%3D%20%5Cfrac%7B%5Cphi_i%20-%20%5Cphi_f%7D%7B%5CDelta%20t%7D)
now we will have
![EMF = \frac{NBA - 0}{\Delta t}](https://tex.z-dn.net/?f=EMF%20%3D%20%5Cfrac%7BNBA%20-%200%7D%7B%5CDelta%20t%7D)
![EMF = \frac{50(1.5)(0.25)}{0.10}](https://tex.z-dn.net/?f=EMF%20%3D%20%5Cfrac%7B50%281.5%29%280.25%29%7D%7B0.10%7D)
![EMF = 187.5 Volts](https://tex.z-dn.net/?f=EMF%20%3D%20187.5%20Volts)
So the induced EMF in the coil will be 187.5 Volts
Answer:
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific materials and Magnetic separations take advantages of natural magnetic properties between minerals in feed. The separation is between economic ore constituents, noneconomic contaminants and gangue. and saw dust can be separated by gravity separation method. The process can be used for separating insoluble substances which are heavier than liquid by allowing them to settle down on their own due to gravity. The mixture of sand and iron can be separated from each other by using a magnet. Iron gets attracted towards a magnet leaving behind the sand.

Answer:
Explanation:
The probability to find a particle in a 1 dimension box of length is:
![P=\int^{2a/3}_{a/3}\Psi^{2}dx](https://tex.z-dn.net/?f=P%3D%5Cint%5E%7B2a%2F3%7D_%7Ba%2F3%7D%5CPsi%5E%7B2%7Ddx)
Let's recall the wave function of a particle in this candiction will be:
![\Psi=\sqrt{\frac{2}{a}}sin\left(\frac{n\pi x}{a}\right)](https://tex.z-dn.net/?f=%5CPsi%3D%5Csqrt%7B%5Cfrac%7B2%7D%7Ba%7D%7Dsin%5Cleft%28%5Cfrac%7Bn%5Cpi%20x%7D%7Ba%7D%5Cright%29)
So the propability:
Solving the integral, it is:
We can cancel out <em>a</em> and using n = 10, the probabilty finally will be:
