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?

B. $\sqrt{2} T$.
C. $T$.
D. $T / \sqrt{2}$.
E. $T / 4$.

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.

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?

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?

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.

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?
