A vertical conducting bar forms a complete rectangular loop with the conductor it is sliding on. The vertical bar is moving to the right at a constant speed in a region with a uniform external magnetic field. Points A and B are the same distance on each side from the sliding bar. Three students make the following statements about the total magnetic field at A and B. Which of these students is correct?
Antonio: "I think the magnetic field at points A and B will be the same since they are the same distance from the vertical bar."
Brooke: "I think the magnetic field at point A is the same as the external field because it is outside the oop and at point B it will be large."
Carlos: "No, I thin the magnetic fields at points A and B will both be larger than the external field due to the induced magnetic field."

Farrow Co. expects to sell 150,000 units of its product in the next period with the following results:
Sales (150,000 units) $2,250,000
Costs and expenses:
Direct materials 300,000
Direct labor 600,000
Overhead 150,000
Selling expenses 225,000
Administrative expenses 385,508
Total costs and expenses $1,660,500
Net income $ 589,500
The company has an opportunity to sell 15,000 additional units at $12 per unit.
The additional sales would not affect its current expected sales.
Direct materials and labor costs per unit would be the same for the additional units as they are for the regular units.
However, the additional volume would create the following incremental costs:
(1) total overhead would increase by 15% and
(2) administrative expenses would increase by $64,500

Calculate the combined total net income if the company accepts the offer to sell additional units at the reduced price of $12 per unit.

Equal annual payments under the lease are $105,000 (including $5,000 annual executory costs) and are due on December 31 of each year. The first payment was made on December 31, 2014, and the second payment was made on December 31, 2015. The five lease payments are discounted at 10% over the lease term. The present value of minimum lease payments at the inception of the lease and before the first annual payment was $417,000. Roe appropriately accounts for the lease as a capital lease.
