1. You have the opportunity to purchase NFL Franchise. The probability distribution of expected returns for the franchise is as follows: What is the expected rate of return for an investment in Franchise A? What is the standard deviation? Solution Answer:- Standered Deviation = (R% - Expected return)2 * Pi = 119.472 = 10.93Probability (Pi)Rate of return (R%)Expected return = (Pi * R%)(R% - Expected return)2 * Pi.1-20%=(.1 * -20%) = -2%=(20% - 6.3%)2 * .1 = 69.169.20%0%0.47%2.8%.19...

A 1.40 kg object is held 1.15 m above a relaxed, massless vertical spring with a force constant of 300 N/m. The object is dropped onto the spring. How far does the object compress the spring? m Repeat part (a), but now assume that a constant air-resistance force of 0.600 N acts on the object during its motion. m How far does the object compress the spring if the same experiment is performed on the moon, where g = 1.63 m/s2 and air resistance is neglected? m Solution ...

#2. Nelson 7.3 which is the following: You are trying to make artificial blood cells. You have managed to get pure lipid bilayers to form spherical bags of radius 10um, filled with hemoglobin. The first time you did this, you transferred the "cells" into pure water and they promptly burst, spilling the contents. Eventually you found that transferring them to a 1 mM salt solution prevents bursting, leaving the "cells" spherical and full of hemoglobin and water when you try this? ...

11. Compare the location of the ovule in the pine and the flowering plant. 12. What is the difference between pollination and fe Solution In pine, ovule is located in the seed cones and in flowering plants the ovule is located in fruit. Pollination is the transfer of pollen from the anther to the stigma of the same or different flower whereas fertilization occurs when the pollen grain reaches the stigma producing a pollen tube, which then grows down through the style to the ovary.
