A mechanical system comprises three subsystems in series with reliabilities of 98%, 92%, and 87%. What is the overall reliability of the system?

Suppose you have two boxes in front of you. One box contains a Thevenin Equivalent (voltage source in series with a resistor) and the other box contains a Norton Equivalent (current source in parallel with a resistor).

3. Suppose that a class named Bicycle contains a private nonstatic integer named height, a public nonstatic String named model, and a public static integer named wheels.

Suppose you are designing a network of tree topology to connect n cities. For each pair of cities, say, ci and cj, the profit to build a fiber cable connecting ci and cj is given.

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.
