Consider the following three machine instructions, which appear in memory starting at the address 0x0000000080001270.
Address (in hex)
Contents (in hex)
0x0000000080001270
0x94000018
0x00000000800012D0
0x94000A53
0x00000000800012D4
0xD61F03C0
"Disassemble” the instructions; that is, give an assembly language program segment that would be translated into the given machine language. Use numeric rather than symbolic register names. Handle branches and jumps specially; where you would normally have a label, provide instead a hexadecimal byte address.

An ideal germanium pn junction diode has the following parameters: Na = 4 × 10¹5 cm³,
Na = 2 × 10¹7 cm³, D₂ = 48 cm²/s, D₁ = 90 cm²/s, Tpo = T = 2 × 10-6 s, and
A = 104 cm². Determine the diode current for (a) a forward-bias voltage of 0.25 V
and (b) a reverse-biased voltage of 0.25 V.
7.20 (a) The peak electric field in a reverse-biased silicon pn junction is |E|= 3 × 105 V/cm.
The doping concentrations are N = 4 × 10¹5 cm³ and N. = 4 × 107 cm³. Find the
magnitude of the reverse-biased voltage. (b) Repeat part (a) for N₁ = 4 × 10 16 cm³ and
N₁ = 4 × 10¹7 cm³. (c) Repeat part (a) for Nd = N₁ = 4 × 10¹7 cm³.

Patriot Ships is a new cruise line company which has a fleet of 10 cruise ships, each with a capacity of 300 passengers. To manage its operations efficiently, the company is looking for a program that can help track its fleet, manage bookings, and calculate revenue for each cruise. Each cruise is tracked by a Cruise Identifier (must be 5 characters long), cruise route (e.g. Miami to Nassau), and ticket price. The program should also track how many tickets have been sold for each cruise. Create an object-oriented solution with a menu that allows a user to select one of the following options: 1. Create Cruise – This option allows a user to create a new cruise by entering all necessary details (Cruise ID, route, ticket price). If the maximum number of cruises has already been created, display an error message. 2. Search Cruise – This option allows to search a cruise by the user provided cruise ID. 3.
