Suppose that the index model for stocks A and B is estimated from excess returns with the following results: $R_A = 4.5\% + 1.40R_M + e_A$ $R_B = -2.2\% + 1.70R_M + e_B$ $\sigma_M = 24\%; R - square_A = 0.30; R - square_B = 0.20$ Break down the variance of each stock to the systematic and firm-specific components. Note: Do not round intermediate calculations. Calculate using numbers NOT in decimal form. For example use "20" for calculation if standard deviation is provided as 20%. Round your answers to nearest whole number. | | Risk for A | Risk for B | |-------------|------------|------------| | Systematic | | | | Firm-specific | | |

(a) Calculate the self-inductance of a toroidal coil consisting of 1000 turns of wire, each of radius 1 cm wound uniformly on a non-ferromagnetic ring of mean radius 10 cm. (b) A circuit containing an air-cored solenoid of self-inductance 0.1 H carries a steady current of 1 A. A switch in the circuit is opened, reducing the current to zero in a time of 1 ms. Determine the magnitude of the induced emf across the solenoid, assuming the current falls to zero at a constant rate.
