A process is said to be reversible if the system can be returned to its initial conditions.

Entropy is a thermodynamic state property.

Analyze the code segment below:01 x = [“Java is hard”, “Python is easy”]02 y = [“Java is hard”, “Python is easy”]0304 print(x == y)05 print(x is y)What would be the output of line 5?

For incompressible substances, the work done during a steady flow process is proportional to the specific volume, so v should be kept as small as possible during a compression process to minimize the work input.

Fill in the Blank.  A Carnot cycle is a reversible cycle composed of four reversible processes: two [a1] and two [a2].

Rate of force development tends to lag behind the ability to produce strength irrespective of time (maximal strength). 

A proton travels in the plane of the screen, as shown, at a constant speed through two separate shaded regions of magnetic field, B1 and B2. The magnetic field in each shaded region is perpendicular to the plane of the screen and uniform in magnitude and direction. The magnetic field is zero outside of the shaded regions. Which statements are correct based on the information shown  about the trajectory of the proton? I. B1 points out of the page. II. The magnitude of B1 is greater than B2 . III. The proton spends more time in region 1 than region 2.

Problem 2: Generate a Class Diagram for Bike ordering system. A bike store sells bikes. Bikes consist of 2 wheels, 1 crank, and 1 stern. System needs to store Serial number and model type for each bike. For a customer the system stores customer id, name, and address. There are two types of Store Employees: Full time and Part time. System needs to store Employee ID, name, and address. Customer originates a Sales Order. One customer can buy more than one bike. A Sales Order consists of Order ID, Date. An Employee interacts with the customer to place the Sales Order. Sales Order contains information about one or more bikes being sold. System needs to keep track of employee who dealt with the customer for that particular order. It also needs to allow for the customer to have more than one order and keep details of employee and order for each order.

Problem 3: Generate a State Diagram for the copy machine. Initially the copy machine is in off state. When power is turned on, the machine reverts to a default state – one copy, automatic contrast, and normal size. While the machine is warming it flashes the ready light. When the machine completes the internal testing, the ready light stops flashing and remains on. Now the machine is ready for copying. The operator may change any of the parameters when the machine is in ready state. The operator may increment or decrement the number of copies, change the size, toggle between automatic and manual contrast, and change the contrast when auto-contrast is disabled. When the parameters are properly set, the operator pushes the start button to begin making copies. Ordinarily copying proceeds until all copies are made. Occasionally the machine may jam or run out of paper. When the machine jams, the operator may clear the blockage and the machine will resume making copies. Adding paper allows the machine to proceed after running out of paper.
