Analyzing Disclosures Regarding Fixed Assets: The exhibit below presents selected financial statement data for three chemical companies: Monsanto Company, Olin Corporation, and NewMarket Corporation. Depreciable assets at cost: Beginning of year End of year Accumulated depreciation: Beginning of year End of year Net income Depreciation expense NewMarket Monsanto Olin Corporation Company Corporation $752 $4,611 $1,796 777 4,604 1,826 584 2,331 611 2,517 33 267 55 27 328 72 Sources: NewMarket Corporation, Form 10-K for the Fiscal Year ended December 31, Year 4; Monsanto Company, Form 10-K for the Fiscal Year ended August 31, Year 4; and Olin Corporation, Form 10-K for the Fiscal Year ended December 31, Year 4. REQUIRED: a. Compute the average total depreciable life of assets in use for each firm. b. Compute the proportion of depreciable assets consumed for each firm at the end of the year. c. Use your answers to part a and b to estimate the number of years until the assets are fully depreciated and might have to be replaced.

Title: Designing a Circuit for Hall Effect Sensor with Specific Requirements Your Specific Requirements: The Hall Effect sensor must be able to operate with a power supply of 38V DC. It should provide a linear DC voltage output relative to the strength of the magnetic field (B) within the range of -35 mT to +35 mT. The Hall Effect sensor will have a built-in difference amplifier, so no additional amplifier is necessary. However, the sensor will be operated in an environment subject to electrical noise in the frequency range of 150 kHz up to some unknown high frequency. To prevent unwanted oscillations due to induced noise, a passive filter should be added to the output of the sensor to eliminate the noise. General Requirements For All Projects: 1. If the sensor needs to be powered with a voltage or current source, specify which and what the source needs to be (DC with amplitude, or AC with amplitude and frequency). Avoid overpowering the sensor. Specify any additional series resistors, if needed. 2. For any components including resistors, capacitors, or inductors you add to your system, values must be specified. 3. Op amps must be shown with input and output connections. Any input and feedback components (resistors, capacitors, inductors) must be shown connected to the op amp with appropriate values identified. 4. If a passive filter is designed, components must be shown in the diagram with appropriate values calculated. 5. Specify the expected range of your output. For example, if it's a DC voltage output, examples might be 0 to 5V or -250mV to +250mV. 6. Specify the expected sensitivity of your sensor system. Typical ways to express sensitivity (hypothetical numbers) are: Temperature sensor: 25mV/C, Linear displacement sensor: 4mV/mm, Rotational displacement: 5mV/degree of rotation, Photodetector: 0.8A/W or 150mV/W. Permitted Components List: - Resistors and Potentiometers (any value) - Capacitors (any value) - Inductors (any value) - Op amp - TL081CP - Frequency-to-voltage converter (frequency discriminator: LM331 (Vour=0.0007fiN)) - Thermocouple Cold Junction Compensation/Amplifier - Omega - Voltage Sources (any model) - Current Sources (any model) - Function Generator (any model)

Margin of Safety a. If Canace Company, with a break-even point at $502,200 of sales, has actual sales of $810,000, what is the margin of safety expressed (1) in dollars and (2) as a percentage of sales? Round the percentage to the nearest whole number. 1. 2. % b. If the margin of safety for Canace Company was 20%, fixed costs were $1,166,400, and variable costs were 80% of sales, what was the amount of actual sales (dollars)? (Hint: Determine the break-even in sales dollars first.)
