A long, thin solenoid has 600 turns per meter and radius 2.6 cm. The
current in the solenoid is increasing at a uniform rate dI/dt. The induced
electric eld at a point near the center of the solenoid and 3.80 cm from
its axis is 8.00 10 -5 V/m. Calculate dI/dt

2. Why is it useful to have mechanisms for direct cell to cell communication and for long distance communication with cells not near each other?

3. Why would bacterial cells need to communicate with each other? What is the advantage? Find an example bacteria that communicate and how do they communicate?

please answer both questions

White light falls in, near the normal direction, against a thin oil film lying on a glass plate. Two colors with wavelengths of 525nm and 650nm clearly dominate the reflected light. Assume that the refractive index of the oil is 1.25 and the refractive index of the glass is 1.5.

Determine the thickness of the film and the order of interference for the dominant colors.

One positive and one negative charges identical in magnitude are place near each other. At halfway between the two charges...

All else equal, firms with higher leverage (D/E ratio) tend to have higher betas. However, when firms are heavily levered (near the “zone of insolvency” or bankruptcy), their betas tend to drop significantly. Without mentioning anything about the equation for beta, briefly explain why this phenomenon might occur.

This is really a business ethics question

Some would say that given the rash of ethical scandals in the last 20 years, that ethical business behavior is waning. Given what you now know about corporate governance, do you think that ethics will be more or less important to business in the near future? In the distant future?

Mears Production Company makes several products and sells them for an average price of $85. Mears' accountant is considering two different approaches to estimating the firm's total monthly cost function, account analysis and high-low. In both cases, she used units of production as the independent variable. For the account analysis approach, she developed the cost function by analyzing each cost item in June, when production was 1,750 units. The following are the results of that analysis:

For the high-low method, she developed the cost function using the same data from June and data from May, when production was 2,450 units and total costs were $47,722.

After developing the two cost functions, the accountant used them to make predictions for the month of December, when production was expected to be 2,275 units.

REQUIRED [ROUND UNIT COSTS TO THE NEAREST CENT AND TOTAL COSTS TO THE NEAREST DOLLAR.]

Part A (5 tries; 5 points)
1. Using account analysis, what was the accountant's estimate of total fixed costs for December?    

2. Using account analysis, what was the accountant's estimate of variable costs per unit for December?   

Part B (5 tries; 5 points)
1. Using the high-low method, what was the accountant's estimate of total fixed costs for December?    

2. Using the high-low method, what was the accountant's estimate of total variable costs for December?

Mears Production Company makes several products and sells them for an average price of $85. Mears' accountant is considering two different approaches to estimating the firm's total monthly cost function, 1) account analysis, and 2) high-low. In both cases, she used units of production as the independent variable. For the account analysis approach, she developed the cost function by analyzing each cost item in February, when production was 1,700 units. The following are the results of that analysis:

For the high-low method, she developed the cost function using the data from February above and data from May, when production was 2,500 units and total costs were $46,928.

After developing the two cost functions, the accountant used them to make predictions for the month of October, when production was expected to be 2,250 units.

Mears Production Company makes several products and sells them for an average price of $90. Mears' accountant is considering two different approaches to estimating the firm's total monthly cost function, 1) account analysis, and 2) high-low. In both cases, she used units of production as the independent variable. For the account analysis approach, she developed the cost function by analyzing each cost item in June, when production was 1,550 units. The following are the results of that analysis:

For the high-low method, she developed the cost function using the data from June above and data from August, when production was 2,350 units and total costs were $41,263.

After developing the two cost functions, the accountant used them to make predictions for the month of December, when production was expected to be 1,725 units.

Cost of Production Report: No Beginning Inventories
Howell Paving Company manufactures asphalt paving materials for highway construction through a one-step process in which all materials are added at the beginning of the process. During April 2017, the company accumulated the following data in its process costing system:

Manufacturing overhead is applied at the rate of $6 per equivalent unit (ton) processed.

Prepare a cost of production report for April.
