Answer:

the total charge which crosses into the collector is 60 nC

Explanation:

Given the data in the question;

current flowing into the collector lead of the bipolar junction transistor (BJT); i = 1 nA = 10⁻⁹ A

no charge was transferred in or out of the collector lead prior to t = 0

the current flow time t = 1 min = 60 sec

Now we write the relation between current, charge, and time;

i = dq / dt

where i is current, q is charge and t is time. { d refers to change }

Now,

\(q=\int\limits^t_{t=0} {i(t)} \, dt\)

\(q=\int\limits^{t=60}_{t=0} { (10^{-9}) } \, dt\)

\(q = ( 10^{-9}) (t)_0^{60\)

\(q = ( 10^{-9}) ( 60 - 0 )\)

q = 60 × 10⁻⁹ C

q = 60 nC

Therefore, the total charge which crosses into the collector is 60 nC

Turbines, positive displacement pumps, and compressors require relief devices on their discharge lines for overpressure protection.

        A relief device is a mechanism or arrangement that releases gas or liquid from a system during an emergency or overpressure situation.

        A relief valve is a type of safety valve that automatically releases material from a vessel or pipeline to protect it from overpressure. It's a critical component of any mechanical system that involves steam, gas, or liquid under pressure because it can prevent significant damage or failure if pressure levels exceed safe limits.

       Turbines, positive displacement pumps, and compressors, for example, are typical mechanical systems that require relief valves for overpressure protection. These devices work by preventing system overpressure from causing damage or bursting the vessel by releasing pressure in a controlled manner.

Let's look at the main components of a relief valve:

Disc: The disc is the component that covers the seat and blocks flow through the valve. The disc lifts when the pressure reaches the set point.

Spring:  The spring is the component that determines the valve's set point. When the set pressure is reached, the spring compresses, and the valve lifts.

Seat: The seat is the component that the disc rests on when the valve is closed.

Bonnet: The bonnet is the component that houses the spring, disc, and seat when the valve is closed.

Nozzle: The nozzle is the component that directs the flow out of the valve when it opens.

A divided-highway-ends sign indicates that the divided highway on which a driver is traveling will come to an end. This sign serves as a warning to motorists that they will be transitioning from a divided highway.

The purpose of a divided-highway-ends sign is to inform drivers of the upcoming change in road conditions. Divided highways are designed to enhance safety by separating opposing lanes of traffic, reducing the risk of head-on collisions and providing controlled access points. However, there are instances where a divided highway may come to an end, typically due to changes in road design or infrastructure. When drivers encounter a divided-highway-ends sign, they should be prepared for several changes in road conditions. Firstly, the physical barrier or median that separated opposing traffic will cease to exist, and drivers will need to adjust their driving behavior accordingly. Drivers should pay close attention to any accompanying signage or road markings that indicate the new road conditions. It is important to follow any posted instructions, adjust speed accordingly, and be prepared for possible changes in traffic flow or road configuration. A divided-highway-ends sign alerts drivers that they are approaching the end of a divided highway and will be transitioning to a regular undivided roadway. Motorists should be prepared for changes in traffic conditions, exercise caution, and adhere to any new signage or road markings to ensure a safe and smooth transition.

When an air traffic controller issues radar traffic information in relation to the 12-hour clock, they reference the aircraft's magnetic heading (C). The 12-hour clock method is a simple way to describe the position of other aircraft in relation to the aircraft receiving the information. This method helps pilots visualize the relative location of nearby traffic.

The controller will provide information such as the distance, direction, and altitude of the other aircraft, using the 12-hour clock as a reference. For example, if the controller says "traffic at 2 o'clock," it means the other aircraft is to the right and slightly ahead of the aircraft receiving the information.

Magnetic heading is used because it takes into account the magnetic variation that can affect an aircraft's compass, making it more accurate and relevant for navigation purposes. True course and ground track, options A and B, are not used in this context as they do not provide a common reference point for both the controller and the pilot to understand the position of nearby traffic.
