What is the maximum number of 12-2 with ground nonmetallic-sheathed cables permitted in an 18-cubic-inch device box if two single-pole switches on one yoke are also in the box?

Nitrogen at an initial state of 300 K, 150 kPa and 0.2 m3is compressed slowly in an isothermal process to a final pressure of 800 kPa. Determine the work done to the nitrogen and the amount of heat transfer during this process.

The future goal of health information is appropriate access to ubiquitous, personalized, specific information relevant to the situation, available to those who should have access to it, while honoring the privacy, security and confidentiality of

11. A heat engine operates between two reservoirs at 800 and 20°C. One-half of the work output of the heat engine is used to drive a Carnot heat pump that removes heat from the cold surroundings at 2°C and transfers it to a house maintained at 22°C.

In the early stages of an action, the herbicide "Spartan Green" is planned to be applied to kill the vegetation onsite so the site can be cleared. If the equilibrium concentration of Spartan Green in the soil after a big rainfall event is 1,312.

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.

A scientist who is evaluating an ancient human skeleton for signs of vitamin and nutrient deficiency is conducting:
