Automated payroll system with GPS tracking and image capture
The local municipality department has been struggling to keep up with the maintenance of water pipes and this issue in turn affects the water supply to the community. The department has seen a trend of repeated calls logged of the same faulty pipes that were claimed to have been repaired previously in the same month. On the other hand, the finance department has raised an issue of a high volume of overtime claim maintenance of these water pipes. Management has decided to deal with these issues by developing an application for water pipe fault maintenance and resolution. The fault resolution component will track the time it took a technician to resolve the water pipe and allow them to upload the site pictures (before and after). This automated payroll system doubles up as a web and Android application – while the technician will use the Android interface, the admin (usually the HR) will use the web interface. When an employee logs into the system from an Android device and their image is captured, then the system sends the technician’s image and their GPS location to the Admin.
If the technician stays logged into the application via an Android device, the GPS location will continue to be automatically updated and forwarded to the admin every five minutes. When the technician logs out, their image and GPS location are again sent to the Admin. This application allows Admins to keep track of employee attendance and payroll. The admin creates employee profiles for each employee by entering all the relevant personal information (name, job position, qualification, etc.). They can also check the salary details and breakdown of the salary of each employee by entering the employee ID and date.
Since the application is GPS-enabled, no employee can add proxy attendance. Admin can view latitude and longitude of the GPS location sent by the employee. When the HR login to the system he can check the GPS location of the employee by entering employee ID and date. This enables the HR to keep an accurate record of working days including overtime worked of individual employees and tweak their payroll accordingly.

technician a says installing a 15.5'' (39.4-cm) clutch is exactly the same procedure as a 14'' (35.6-cm) clutch. technician b says that the 15.5'' (39.4-cm) clutch is heavier and a purpose-built jack must be used for installation. who is correct?
Technician B is correct. The 15.5'' (39.4-cm) clutch is heavier than the 14'' (35.6-cm) clutch and therefore requires a purpose-built jack for installation.
A clutch is a mechanical device used in vehicles with manual transmissions to engage and disengage power transmission between the engine and the transmission. It allows the driver to control the transfer of power from the engine to the wheels.The clutch consists of several components, including the clutch disc, pressure plate, flywheel, and release bearing. When the clutch pedal is pressed, it disengages the clutch, separating the clutch disc from the flywheel. This interrupts the power flow from the engine to the transmission, allowing the driver to change gears or come to a stop without stalling the engine

We have a 60W resistance, a 20W, and an unknown resistance Rx in parallel with a 15mA current source. The current through the unknown resistance is 10 mA. Determine the value of Rx.
The current through the unknown resistance is 10 mA. The value of Rx is 0.7W.
To solve this problem, we can use Ohm's Law and the formula for calculating total resistance in a parallel circuit:
1/Rt = 1/R1 + 1/R2 + 1/Rx
where Rt is the total resistance of the circuit, R1 and R2 are the known resistances (60W and 20W, respectively), and Rx is the unknown resistance.
We know that the current through the unknown resistance is 10mA, so we can use Ohm's Law to find the voltage drop across it:
V = IR
V = (10mA)(Rx)
V = 0.01Rx volts
We also know that the total current in the circuit is 15mA, so we can use Kirchhoff's Current Law to find the current through the known resistances:
I1 + I2 + Ix = Itotal
Ix = Itotal - I1 - I2
Ix = 15mA - 60W/120V - 20W/120V
Ix = 15mA - 0.5mA - 0.17mA
Ix = 14.33mA
Now we can use Ohm's Law again to find the resistance of the unknown resistor:
Rx = V/Ix
Rx = 0.01Rx / 14.33mA
Rx = 0.7W
Therefore, the value of Rx is 0.7W.
