Write the inputRecordings() method in the Collection class. Within inputRecordings(), use scnr to read each row number until -1 is read from input. If the row number is not equal to -1: Create a new Recording object. Use the Recording object's readDetails() method to read the recording's topic and discount from input. Append the Recording object to ArrayList recordingList.

If the masses of the fission products, 93Kr and 140Ba, resulting from the fission of 235U from thermal neutrons are 92.92024 amu and 139.9106 amu, respectively, and three neutrons are released, calculate the Q-value for this fission process. Mass of 235U = 235.04393 amu, mass of neutron = 1.008713 amu

Prove that if alpha is a Rayleigh distributed RV, then the pdf of alpha ^(2) is given by p(alpha ^(2))=(1)/(/bar (alpha ^(2)))e^(-(alpha ^(2))/(/)bar (alpha ^(2))). This is the Chisquare pdf with two degrees of freedom. Using this result, show that the pdf of instantaneous SNR in a Rayleigh fading channel is given by p(gamma )=(1)/(gamma _(0))exp(-(gamma )/(gamma _(0))), where gamma _(0) is the average SNR. 3) Prove that if is a Rayleigh distributed RV, then the pdf of 2 is given by p(2) = e-/2. This is the Chi- square pdf with two degrees of freedom. Using this result, show that the pdf of instantaneous SNR in a Rayleigh fading channel is given by p() = 1 exp(-/Yo) , where Yo is the average SNR. Yo

(3) Based on the definition of work, the applied force is given by the expression below in terms of $W$, the work done by the worker. Substitute numerical values to find the value of the applied force. (Enter a value for $\theta$ that is $0 \le \theta < 360.$) $F = \frac{W}{\Delta r \cos \theta}$ $= \frac{320}{(15 \text{ m}) \cos \text{____}^{\circ}} = \text{____ N}$
