Given that the area immersed in the gap is changing as the coil enters the gap, what is the correct expression of Faraday's Law
zvonat [6]

Complete Question

The complete question is  shown on the first uploaded image

Answer:

 The  induced emf  is  \epsilon   =  B *  l * v

Step-by-step explanation:

Now assume that the coil is  shaped as a rectangle with length  l and  width b

   This  implies that the area of the coil is  A=  l *  b

Now when it enter into the uniform magnetic field the magnetic flux due to its movement as stated in the question is mathematically represented as

        \phi =  BA

=>    \phi =  B  (l* b  )

Now the induced emf is  mathematically represented as

          \epsilon   =  \frac{d\phi}{dt}

=>       \epsilon   =  B *  l  [\frac{db}{dt} ]

The  l  is constant because as it glides to and from the magnetic field it is displaced along the horizontal plane while along the vertical plane it is constant

Here  \frac{db}{dt}  = v

Where is the velocity the glide (i.e the coil)

So

       \epsilon   =  B *  l * v

Let X denote the temperature (degree C) and let Y denote thetime in minutes that it takes for the diesel engine on anautomobile
BlackZzzverrR [31]

Answer:

Step-by-step explanation:

Given f_{XY} (x,y) = c(4x + 2y +1) ; 0 < x < 40\,and\, 0 < y

a)

we know that \int\limits^\infty_{-\infty}\int\limits^\infty_{-\infty} {f(x,y)} \, dxdy=1

therefore \int\limits^{40}_{-0}\int\limits^2_{0} {c(4x+2y+1)} \, dxdy=1

on integrating we get

c=(1/6640)

b)

P(X>20, Y>=1)=\int\limits^{40}_{20}\int\limits^2_{1} {\frca{1}{6640}(4x+2y+1)} \, dxdy

on doing the integration we get

                        =0.37349

c)

marginal density of X is

f(x)=\int\limits^2_{0} {\frca{1}{6640}(4x+2y+1)} \, dy

on doing integration we get

f(x)=(4x+3)/3320 ; 0<x<40

marginal density of Y is

f(y)=\int\limits^{40}_{0} {\frca{1}{6640}(4x+2y+1)} \, dx

on doing integration we get

f(y)=\frac{(y+40.5)}{83}

d)

P(01)=\int\limits^{40}_{0}\int\limits^2_{1} {\frca{1}{6640}(4x+2y+1)} \, dxdy

solve the above integration we get the answer

e)

P(X>20, 0

solve the above integration we get the answer

f)

Two variables are said to be independent if there jointprobability density function is equal to the product of theirmarginal density functions.

we know f(x,y)

In the (c) bit we got f(x) and f(y)

f(x,y)cramster-equation-2006112927536330036287f(x).f(y)

therefore X and Y are not independent
