A satellite is in a 1.5-hour-period circular orbit around Earth. If the satellite moves to a new orbit with radius twice that of the original, the new period is (a) $2.4$ hours; (b) $2.8$ hours; (c) $3.0$ hours; (d) $4.2$ hours.

A mass $m$ is suspended from the ceiling of an elevator by a spring of force constant $k$. When the elevator is at rest, the period of the mass is T. Does the period increase, decrease, or remain the same when the elevator moves upward with constant speed?

What would be the period of a 2.0-m-long pendulum on the Moon’s surface? The Moon’s mass is $7.34 \times 10^{22} \mathrm{kg}$, and its radius is $1.74 \times 10^{6} \mathrm{m}$. What is the period of this pendulum on Earth?

Suppose y = g(x) is a periodic trigonometric function with a period of $5\pi$ radians and amplitude of $6\pi$ feet when x is measured in radians. What would be the period and amplitude of g(x) if x were measured in degrees and y were measured in yards?

What are the amplitude, period, and frequency of each function?

$$y = 4 \sin 2 x$$

What period of human development brings about the most rapid change?

Santa Fe Retailing purchased merchandise "as is" (with no returns) from Mesa Wholesalers with credit terms of 3/10, n/60 and an invoice price of $24,000. The merchandise had cost Mesa$16,000. Assume that both buyer and seller use a perpetual inventory system and the gross method.

1. Prepare entries that the buyer records for the (a) purchase, (b) cash payment within the discount period, and (c) cash payment after the discount period.
2. Prepare entries that the seller records for the (a) sale, (b) cash collection within the discount period, and (c) cash collection after the discount period.

You need to borrow $\$ 4,000$ for $9$ months. The local bank is willing to supply the money at $9 \%$ simple interest. Calculate the amount of interest that will be paid on the loan for the stated period and the total amount required at the end of the period. [3.1]

Find the period, and sketch the graph.

y = sec (1/2x - pi/6)

The pressure P (in millimeters of mercury) against the walls of the blood vessels of a patient is modeled by

$$P=100-20cos(8π/3t)$$

where t is time (in seconds). What is the period of the model? What does the period tell you about this situation?

A mass $m$ is suspended from the ceiling of an elevator by a spring of force constant $k$. When the elevator is at rest, the period of the mass is T. Does the period increase, decrease, or remain the same when the elevator moves upward with constant acceleration?

Assume you deposit 25% of your monthly check of $5500 into a savings account at a credit union that compounds interest semiannually. (a) What are the payment and compounding periods? (b) Is the payment period greater than or less than the compounding period?

Susan Braun’s regular hourly wage rate is $16, and she receives an hourly rate of$24 for work in excess of 40 hours. During a January pay period, Susan works 47 hours. Susan’s federal income tax withholding is $95, and she has no voluntary deductions. Compute Susan Braun’s gross earnings and net pay for the pay period. Assume that the FICA tax rate is 7.65%.

Prepare the employer’s journal entries to record (a) Susan’s pay for the period and (b) the payment of Susan’s wages. Use January 15 for the end of the pay period and the payment date.
