A point charge with charge q1 = 3.50 μC is held stationary at the origin. A second point charge with charge q2 = -4.80 μC moves from the point ( 0.170 m , 0) to the point ( 0.255 m , 0.260 m ). How much work W is done by the electric force on the moving point charge?

Express your answer in joules. Use k = 8.99×10⁹ N⋅m^2/C^2 for Coulomb's constant: k=1/4πϵ0.

An atom of beryllium (m = 8.00 u) splits into two atoms of helium (m = 4.00 u) with the release of 92.2 keV of energy. Suppose the beryllium atom moved in the positive x direction and had a kinetic energy of 44.0 keV. One of the helium atoms is found to be moving in the positive x direction. Find the direction of motion of the second helium, and find the velocity of each of the two helium atoms. Solve this problem in two different ways: by direct application of conservation of momentum and energy; and by applying the results if the original beryllium atom is at rest to a frame of reference moving with the original beryllium atom and then switching to the reference frame in which the beryllium is moving.

(a) by direct application of conservation of momentum and energy

(b) by applying the results if the original beryllium atom is at rest to a frame of reference moving with the original beryllium atom and then switching to the reference frame in which the beryllium is moving

The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $830,000, and it would cost another $17,500 to install it. The machine falls into the MACRS 3-year class (the applicable MACRS depreciation rates are 33.33%, 44.45%, 14.81%, and 7.41%), and it would be sold after 3 years for $630,000. The machine would require an increase in net working capital (inventory) of $14,500. The sprayer would not change revenues, but it is expected to save the firm $457,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 40%. What is the Year-0 net cash flow? $ What are the net operating cash flows in Years 1, 2, and 3? Round your answers to the nearest dollar. Year 1 $ Year 2 $ Year 3 $ What is the additional Year-3 cash flow (i.e, the after-tax salvage and the return of working capital)? Round your answer to the nearest dollar. $ If the project's cost of capital is 11 %, what is the NPV of the project? Round your answer to the nearest dollar. $ Should the machine be purchased?

Unlike direct materials, the sum of all the direct labor variances is always equal to the flexible budget variance.

True

False

A negative direct labor efficiency variance is considered favorable.

True

False

For direct labor, if the efficiency and rate variances are both negative, then the flexible budget variance will be unfavorable.

True

False

The total number of hours worked by employees is always directly tied to the total level of production.

True

False

Nike claims that the number of miles a jogger can get a on a pair of Nike’s running shoes is higher than 1000. Moreover, Nike also claims that their shoes outperform Adidas shoes by more than 15 miles. We have samples of 150 joggers using Nike shoes and 170 using Adidas shoes. The sample average of miles they got are 1015 for Nike and 995 for Adidas. The sample standard deviations are 100 for Nike and 50 for Adidas.

In recent years, public universities have experienced major budget cuts due to reduced funding from their state governments. These budget cuts usually occur at the most inopportune time—during the school year when contractual commitments with faculty and staff had been signed, programs had been planned, and students were enrolled and taking classes.

Required:

1. Should the administration be “fair” to all affected and institute across-the-board cuts whenever the state announces a reduction in funding?
2. If not across-the-board cutbacks in programs, then would you recommend more focused reductions, and if so, what priorities would you establish for bringing spending in line with revenues?
3. Since these usually are not one-time-only cutbacks, how would you manage continuous, long-term reductions in budgets extending over a period of years?
4. Should the decision-making process be top-down (centralized with top administrators) or bottom-up (participative)? Why?
5. How should issues such as protect-your-turf mentality, resistance to change, and consensus building be dealt with?
