A purse at radius 2.00 m and a wallet at radius 3.00 m travel in uniform circular motion on the floor of a merry-go-round as the ride turns. They are on the same radial line. At one instant, the acceleration of the purse is (2.00 m/s²)î + (4.00 m/s²)ĵ. At that instant and in unit-vector notation, what is the acceleration of the wallet?

Consider the radial field $\mathbf { F } = \langle f , g \rangle = \frac { \langle x , y \rangle } { \sqrt { x ^ { 2 } + y ^ { 2 } } } = \frac { \mathbf { r } } { | \mathbf { r } | }$.

Let R be the unit disk centered at the origin and compute $\iint _ { R } \left( \frac { \partial f } { \partial x } + \frac { \partial g } { \partial y } \right) d A$.

Which of the following steps is optional during the closing process?

a. Adjusting entries are journalized and posted to the ledger.
b. An end-of-period spreadsheet is prepared.
c. An unadjusted trial balance is prepared.
d. A post-closing trial balance is prepared.

Why are subsidiary shares not reported as stock outstanding in the consolidated balance sheet?

Find the maximum shear stress in a $5 \frac{1}{2}-i n$-diameter circular saw blade if it runs idle at 5000 rev/min. The saw is 14 gauge (0.0747 in) steel and is used on a $\frac{5}{8}$-in-diameter arbor. The thickness is uniform. What is the maximum radial component of stress?

Under the allowance method, how are accounts receivable shown on the balance sheet?

A car travels along a road, which for a short distance is defined by $r=(200 / \theta) \mathrm{ft}$, where $\theta$ is in radians. If it maintains a constant speed of $v=35 \mathrm{ft} / \mathrm{s}$, determine the radial and transverse components of its velocity when $\theta=\pi / 3 \mathrm{rad}$

Write a differential equation for the balance $B$ in an investment fund with time, $t$, measured in years.

The balance is losing value at a continuous rate of $8\%$ per year, and money is being added to the fund at a continuous rate of $\$2000$ per year.

What are the strength and direction of an electric field that will balance the weight of (a) a proton and (b) an electron?

What is the current in a wire of radius R = 3.40 mm if the magnitude of the current density is given by (a)

$$J_a = J_0 r/R$$

and (b)

$$J_b = J_0(1 - r/R)$$

, in which r is the radial distance and

$$J_0 = 5.50 × 10^4 A/m²$$

? (c) Which function maximizes the current density near the wire’s surface?

When evaluating exergy destruction, is it necessary to use an exergy balance? Explain.
