Question 7 (10 points) ✓ Saved Regarding GC (Garbage Collection) in Java, which of the following statements is true? Java developers need to explicitly create a new thread in order to deallocate the used memory space. A Java GC process is responsible to take care of heap memory and deallocate the space occupied by those objects no longer used. The Java memory management API allows developers to write code directly deallocating the used memory space. JDK offers an interface for Java developers to use in managing the memory heap, e.g. deallocate the memory after a given period of time.

Answer:

Step 1: Determine the constants a and b in the Langmuir Equation.

a = 6.0 g/L

b = 1.783 g/L

Step 2: Calculate the dosage required to yield an effluent with a phenol concentration of 0.10 mg/L.

dosage = (2 * 6.0) + (1 * 1.783) = 11.83 g

Switching terminal screws on switches are always connected to the ungrounded conductor.

An electrical circuit can be defined as an interconnection of different electrical components, in order to create a pathway for the flow of electric current (electrons) due to a driving voltage.

In Electrical engineering, a switch can be defined as an electrical component (device) that is typically designed and developed for interrupting the flow of current or electrons in an electrical circuit.

This ultimately implies that, a switch that can open or close an electric circuit should always be connected to the underground conductor, in order to avert any form of hazard and as a safety precaution.

The description for a star cluster is a system of stars held together by gravity that can number from a thousand up to a million stars. The correct option is b.

Due to their location on the dusty spiral arms on the plane of spiral galaxies, they are occasionally referred to as galactic clusters. All of the stars in an open cluster originated from the same initial massive molecular cloud.

The most basic theory states that star cluster when a massive cloud of gas and dust condenses. Once the cloud's center has attracted enough material from its surroundings, star formation can begin.

The statement " it is important to know if a computer is a byte or word addressable because we need to know how many addresses are contained in main memory, cache, and in each block when doing cache mapping" is True.

What is cache mapping?

Simply said, a cache is a block of memory used to store data that will probably be utilized again. Like web servers, the hard drive and CPU frequently employ a cache. The term "cache mapping" describes a method of bringing the information in the main memory into the cache. For cache memory mapping, three different forms of mapping are used: direct, associative, and set-associative mapping.

When we wish to accelerate and synchronize with a high-speed CPU, we use something called cache memory, which is a unique, extremely fast memory. The cache stores frequently requested data and instructions so that the CPU always has access to them when needed.

Architects must consider the availability and cost of building materials when they plan their projects.

Building planning and design are the expertise of an architect, who typically has a significant impact on how a building is built. The art and science of building design are fields in which architects have extensive training. Architects need to be licenced professionally because they are in charge of ensuring the security of the people who use their buildings.

The Greek term for "chief builder" is the origin of the word "architect." Between the craftsman who designed a building and the one who actually built it, there was no distinction for a large portion of history.

False, electric water heaters should be wired with a four-wire cable, as the white conductor in a two wire cable is not permitted to be used as an ungrounded conductor in this type of installation.

Electric water heaters are a common household appliance, providing hot water for bathing, cleaning, and other activities. However, it is important to ensure that they are wired correctly to ensure safety and efficiency. This essay will discuss the importance of using the proper wiring for electric water heaters, including the types of wiring that should be used and the consequences of incorrect wiring.

The most common type of wiring used for electric water heaters is a four-wire cable. This type of wiring is used because the white conductor in a two-wire cable is not permitted to be used as an ungrounded conductor in this type of installation. A four-wire cable consists of two hot wires, a neutral wire, and a ground wire. This type of wiring is essential for proper functioning of the electrical water heater, as it ensures that the appliance is properly grounded and that electricity is supplied in a safe, efficient manner.
