Which of the following is a criticism of Lewis Terman's Study of Genius? Group of answer choices The participants were not studied long enough to see changes over time. The study contained fewer than 500 geniuses. The sample was mostly white, male and from wealthier families. The participants were selected for the study at random rather than selected based on IQ scores.

A pulsed dye laser that is used for the treatment (removal) of port-wine stains from the skin produces laser light at a wavelength of 486 nm. Assume this light is produced by electrons in hydrogen that undergo a transition in the Balmer series. Use the Bohr model to determine the initial energy state ($n_i$) of these electrons.

5. [16 Points] Consider the following two program segments being run on a computer with virtual memory that has ten 4 Kilobyte pages of real memory. Note the only difference in the two segments is that the loops in segment 1 change variable i first then j while segment 2 changes j first then i. int a [1024] [1024]; int b, i, j; /* segment 1 */ b = 0;

A contract has a clause for liquidated damages for breach of contract by one party. Which of the following statements is correct? If the innocent party has suffered no loss, then the liquidated damages clause is a penalty clause and is, therefore, unenforceable. If the actual loss suffered by the innocent party from the breach is substantially less than the liquidated damages, the innocent party may only recover the actual loss. If the contract calls the clause "a penalty clause", the clause will not be enforceable. A liquidated damages clause is enforceable regardless of whether, or how much loss, the innocent party has suffered from the breach.

24. In order to estimate the wage equation, a researcher regresses the log of wage on individual's observed characteristics including years of schooling. In this problem, however, the error term contains unob- served characteristics such as motivation, and it is likely that the error is correlated with the years of schooling, i.e., a highly motivated person tends to study more and also make more money. Which of the following statement is true except (a) The years of schooling is endogenous. (b) The OLS estimator is still consistent and asymptotically normal. (c) The OLS estimator is not unbiased. (d) The instrumental variable method can be used to consistently estimate the coefficients.

A typical hard disk drive actuator can be modeled quite accurately as a double integrator: \begin{equation} G(s) = \frac{Y(s)}{U(s)} = \frac{6 \times 10^7}{s^2} \end{equation} where $y$ is the displacement of the read/write head in micrometer and $u$ is actuator input voltage in volts. The sampling rate used in a typical hard disk drive servo system is about 10 kHz, which is equivalent to a sampling period T = 1/10000 = 0.0001 seconds. It is required to design an appropriate control law such that the resulting closed-loop system has an overshoot less than 25% and a settling time less than 8 milliseconds due to a step reference of 1 micrometer. ... Design a lead compensator that would achieve an overshoot of 25% and a settling time of 8 milliseconds due to a step function of 1 micrometer. Physically realize and digitize the system.
