The midsagittal plane is an imaginary line that divides the patient in right and left equal haves. This line would be:

When utilizing the manual ‘dipping’ processing technique, the amount of time a film needs to be submerged in fixer solution to prevent it from turning brown is:

Problem 3: Part B A vapor compression cycle has a mass flow rate of 0.05 kg/s. R-134a enters the compressor (η = 70%) at 2.8 bar, 70 °C and then is compressed to 9.0 bar. The R-134a exits the condenser as a saturated liquid.   Determine the cooling capacity of the cycle (tons)

Problem 1: Part A An Otto cycle begins with 8.5 L of air at 300 K, 1 bar. The clearance volume is 0.5 L, and the maximum temperature is 1800 K. You may interpolate if the difference between the two numbers is 0.1 or less   On a cold air-standard basis, determine the mean effective pressure of the cycle (kPa)  

Problem 2: Part C A Diesel cycle begins with 10 L of air at 300 K, 1 bar. The cycle operates with a compression ratio of 23.25 and a maximum temperature of 2050 K. You may interpolate if the difference between the two numbers is 0.1 or less   Complete the P-V diagram for the cycle by denoting where states 1, 2, 3, and 4 are:   Submit your completed diagram in your partial work submission.

Adam is the operations manager for Events, LLC, a company that coordinates large-scale outdoor music festivals and corporate events. The owner, Pete, left Adam a note stating: “Adam, please purchase the following items for the company’s upcoming events: 1) 15 industrial-grade portable generators of brand X; 2) 10 large event tents, each costing no more than $100; and 3) 25 VIP restroom trailers with built-in sanitizing stations with premium chemical treatment tanks. Thanks, Boss Pete” Adam contacted a supplier and told the sales representative he was Pete’s agent and needed 15 brand X generators. The representative said that brand Y was in stock and very similar but much cheaper. Without confirming with Pete, Adam agreed to buy 15 brand Y generators and signed the contract as Pete’s agent. When the units arrived, Pete rejected them and refused to pay. Adam contacted a tent rental company and signed a contract in his own name to buy 10 tents at $90 each. He did not tell the company he was acting on Pete’s behalf. The tents were delivered, but Pete decided to cancel the events, so he refused to pay for them. Adam contracted with a manufacturer for 25 VIP restroom trailers with sanitizing stations but without the premium chemical treatment tanks Pete had specified. He told the manufacturer he was acting for a company but did not disclose Pete’s name. Pete used the trailers anyway but now refuses to pay the manufacturer. Assume valid contracts were formed. Who is liable on each of the contracts above? Discuss fully.
