Suppose your wealthy aunt has given you a gift of $25,000. You have come up with three options for spending (or investing) the money. First, you'd like (but do not need) a new car to brighten up your home and social life. Second, you can invest the money in a high-tech firm's common stock. It is expected to increase in value by 20% per year, but this option is fairly risky. Third, you can put the money into a three-year certificate of deposit with a local bank and earn 6% per year. There is little risk in the third option.
If you decide to purchase the new car, what is the opportunity cost of this choice? Explain your reasoning.
If you invest in the high-tech common stock, what is the opportunity cost of this choice? Explain your reasoning.
Find the new angular speed of the student. Calculate the kinetic energy of the system before the student pulls his arms inwards.
Determine Reaction on the cross head guides, Thrust on the crank shaft bearings and (iii) Torque on the crank shaft
you are looking for a power unit to run an irrigation pump in your operation. the pump requires 92 horsepower to turn
water vapor in a piston-cylinder assembly undergoes a process from saturated vapor at 150 c to a pressure of 300 kpa.
Standard atmospheric pressure (numerical value).Be very specific and to the point if you want me to reward you
A force of 300 lbf is applied to the piston of a cylinder, compressing the gas within the cylinder. The piston has a radius on 15 in. If the local atmospheric pressure is 0.98 atm, what is the absolute pressure inside the cylinder in psi
Consider a sphere with a diameter of 20 mm and a sur- face temperature of 60°C that is immersed in a fluid at a temperature of 30°C and a velocity of 2.5 m/s. Calculate the drag force and the heat rate when the fluid is
An office worker claims that a cup of cold coffee on his table warmed up to 80°C by picking up energy from the surrounding air, which is at 25°C. Is there any truth to his claim? Does this process violate any thermodynamic laws?
During the flow, the pressure at the pipe inlet and exit is measured to be 8.25 bar and 0.97 bar, respectively and determine the flow rate of oil through the pipe assuming the pipe is horizontal.
A throttle process is an irreversible process. Assume an air flow at 1000 kPa, 400 K runs through a valve out to ambient 100 kPa. Find the reversible work and irreversibility assuming an ambient temperature of 25°C. Please show and explain in detail.
Why are some of the detectors listed unsuitable for HPLC?
