We are introduced to the magnetic field as a way to keep track of the force that arises from lenght contraction in special relativity. A moving distribution of charge becomes more dense in the right frame. So in a way, the magnetic field is just the E-field. However, when I glance over the physics of permanent magnets, it is said that their magnetic field arises from the integral sum of their electrons with aligned spin(which generates a magnetic moment).Spin is...

Q1. You want to keep the indoor temperature of an office at 25oC. The outdoor temperature is 5oC. The heat transfer through the building’s exterior is 3 x 106 kJ. To achieve the desired indoor temperature, you are exploring three heat pumps operating between the office interior and: (i) the ground at 12oC; (ii) a pond at 10oC; and (iii) the air outside at 5oC. For each case, what is the minimum theoretical net work input (in kJ) any heat...

You are tasked to design an application to keep track of sales for your company. Sales should be tracked for two types of accounts: supplies and services. Complete the following: Create a UML class diagram for the Account inheritance hierarchy. Your subclasses should be Supplies and Services. All sales accounts will have an account ID (accountId). You will need attributes to keep track of the number of hours (numberOfHours) and rate per hour of services provided (ratePerHour)....
