CFA SALT TEST SOLUTIONS (100% Accurate) CFA SALT TEST SOLUTIONS (100% Accurate) A company is able to borrow over 5 years at a 5.7% interest rate. If the nominal risk-free rate is 4% and lenders require premiums of 1% for inflation, 0.8% for liquidity, and 0.4% for maturity, the compensation for the possibility that the company does not repay the loan is closest to: - ANSWER - Remember r = rf + I + D + L + M Nominal risk free rate = rf + I = 4%. I = 1% L = 0.8% M= 0.4% So 5.7 = 4 + D...

In the chromatography of the reaction mixture, water absorbed on cellulose functioned as the stationary phase. What was the principal factor determining the migration of individual components in the sample? A) Hydrogen bonding B) Solute concentration C) Stationary phase concentration D) Thickness of paper - ANSWER A) Hydrogen bonding The answer to this question is A because the relative amount of hydrogen bonding to the stationary phase will determine the relative rate of migration of ...

Rheobase - the lowest point on a strength duration curve at an infinitely long pulse duration Chronaxie time - the pulse width at twice the rheobase value. It approximates the most efficient stimulation pulse duration Charge (formula) - Charge= I(current) x T(time) Furman's formula - Energy(microjoules)= I(current)xV(voltage)xT(pulse width) Ohms law formula - Voltage(electromotive force)= I(current/flow of electrons) x R(resistance to current flow in ohms) Functional Refractory P...
