define admittance, susceptance, and conductance. across 250v, 50hz, single phase supply are connected circuits A and B in parallel. circuit A takes a current of 12 amperes leading by 45 degrees, and circuit B takes a current of 10 amperes lagging by 30 degrees. calculate the conductance, susceptance, and admittance of each circuit. if a capacitance of 10 microfarads is placed in parallel with A and B, find the complex expression for the total current.

what happens the astronaut falls out of his space station and the life line is cut. Though he will survive for some time because of the space suit but will he be able to get back to the space station?? (can he throw out some item from his suit and generate reverse force..newtons' third law)

1)
integrand ((Cos(x))/(1+((sin(x))^2))dx)
upper limit pi/2 and lower limit 0

2)
integrand ((e^(-x))/(1+(e^(-2x)))dx)

Please show your steps.
Answers
1) pi/4
2) -arctan(e^(-x))+c (c is a constant)

Question:
My question is - how difficult of a transition would it be for an AVERAGE intelligence person to switch to science? What steps would I have to take (based on my story below) to accomplish this? Could I still get a bachelors in psychology and (while fulfilling the basic science courses/pre-med courses) go into a science graduate program?
