A sound wave in air has a pressure amplitude equal to 3.92 ✕ 10-3 Pa. Calculate the displacement amplitude of the wave at a frequency of 9.8 kHz. (Note: Use the following values, as needed. The equilibrium density of air is 𝜌 = 1.20 kg/m3; the speed of sound in air is v = 343 m/s. Pressure variations ΔP are measured relative to atmospheric pressure, 1.013 105 Pa.) m

Research reveals that encoding a word's meaning (e.g., whether the word "hat" refers to a type of clothing) leads to better memory of that word compared to encoding a word's visual features (e.g., whether the word "hat" is written in lowercase or uppercase letters). Related neuroimaging research shows that this advantage is related to _____. increased activation of the posterior Parietal lobe increased activation of the right Occipital lobe increased bilateral activation of the Occipital lobe increased activation of the lower left Frontal lobe

Question 1 Suppose a firm is willing to pay an employee $600 per week in total compensation. The worker can either receive the compensation in wages or health insurance. Assume initially that all compensation received by workers is subject to a marginal tax of 30%. a. Placing after tax wages on the vertical axis and the value of health insurance on the horizontal axis, graph the budget constraint faced by the consumer—what are the possible combinations of after-tax wages and insurance that the firm can pay the worker that only cost the firm $600 per week? Label this line segment "a". How much could they spend on health insurance, if they put all of their compensation into health insurance? b. Suppose that wages remain taxable but health insurance is now a tax preferred fringe benefit. Graph the new budget constraint and label it "b". How much could they spend on health insurance, if they put all of their compensation into health insurance? c. Suppose that the marginal tax rate increases from 30 to 40%. Graphically illustrate how this alters the budget constraint from part (b), and label the new line segment "c".
