1. Determine the position in the oscillation where an object in simple harmonic motion: (Be very specific, and give some reasoning to your answer.) a. has the greatest speed
b. has the greatest acceleration
c. experiences the greatest restoring force
d. experiences zero restoring force
2. Describe simple harmonic motion, including its cause and appearance. (Make sure to use your own words, and be very specific. And few examples would be helpful.)
3. Use the information listed in Data Tables 1 to 3 to describe how the change in, using complete sentences:
a. amplitude (angle)
b. length
c. mass affect the period of the pendulum
4. Compare your calculations of g using individual measurements and using the graph in Graph 1, listed in Data Table 4. Do your measurements including uncertainty fall within the accepted value? Which method is more accurate? List possible sources of error in your data and calculations.
5. Was energy conserved during the motion of your pendulum? If not, list some possible ways energy could have been lost from the pendulum system, making sure to use complete sentences. 6. Why did you measure 10 periods of the pendulum instead of just 1? Would your measurements be improved by measuring 100 periods instead of 10? Why or why not? How many periods do you think is the optimal number to measure?

while setting up his new office, an attorney ordered thick, frieze carpets for the floor. however, the building inspector had him remove the expensive carpeting. the building inspector stated that according to federal regulations, the office must be wheelchair accessible as it is a public area. he further explained that since wheelchairs do not maneuver well in thick, frieze carpeting, the carpets had to be removed and be replaced with smooth-textured carpets that do not restrict wheelchair maneuverability. this scenario illustrates how a company is influenced by the component of its specific environment.

Afirm's before-tax cost of debt, rd, is the interest rate that the firm must pay on debt. because interest is tax deductible, the relevant cost of debt used to calculate a firm's wacc is the cost of debt, rd (1 – t). the cost of debt is used in calculating the wacc because we are interested in maximizing the value of the firm's stock, and the stock price depends on cash flows. it is important to emphasize that the cost of debt is the interest rate on debt, not debt because our primary concern with the cost of capital is its use in capital budgeting decisions. the rate at which the firm has borrowed in the past is because we need to know the cost of capital. for these reasons, the on outstanding debt (which reflects current market conditions) is a better measure of the cost of debt than the . the on the company's -term debt is generally used to calculate the cost of debt because more often than not, the capital is being raised to fund -term projects. quantitative problem: 5 years ago, barton industries issued 25-year noncallable, semiannual bonds with a $1,600 face value and a 8% coupon, semiannual payment ($64 payment every 6 months). the bonds currently sell for $845.87. if the firm's marginal tax rate is 40%, what is the firm's after-tax cost of debt? round your answer to 2 decimal places. do not round intermediate calcu
