TLE Practice Test

This question tests knowledge of common plumbing tools and their specific uses. Wrenches, particularly adjustable or pipe wrenches, are the correct tools for manipulating hexagonal fittings. Understanding the appropriate tools for different plumbing tasks is essential for efficient and effective work.

This question tests knowledge of pipe schedules, which indicate the thickness of the pipe wall. Schedule 40 is a standard thickness for many applications, thicker than schedule 20 but thinner than schedule 80. Understanding pipe schedules is crucial for selecting the appropriate pipe for different plumbing applications based on pressure requirements and other factors.

The term "septic" refers to a septic tank, which is a compartment located below the normal grade of the gravity system. It is designed to receive and treat solid and liquid waste from a building. A sump is used to remove water, a trap is a device used to prevent sewer gases from entering the building, and an interceptor is used to separate and retain undesirable matter.

A gate valve is commonly used to shut off the flow of water in a plumbing system. It is designed to completely stop the flow with a 90-degree turn. While angle and globe valves can control water flow, they are not typically used for complete shut-off. A check valve prevents backflow, not for shutting off flow.

PVC pipes commonly come in standard lengths of 10 feet, which is equivalent to about 3 meters. This standard length facilitates easier handling, installation, and fitting during plumbing projects.

The standard length for G.I. (galvanized iron) pipes is typically 6 feet. Knowing this length helps in estimating the number of pipes needed to cover a certain distance from a house to the main supply line.

Applying a darker shade of eye makeup around the eyes can make the natural color of the eyes stand out and appear lighter by contrast. This technique is often used to enhance eye color.

Nails are primarily composed of keratin, a type of protein that forms the structural material for the nail. Collagen is found in skin and connective tissues, sebum is an oily secretion from sebaceous glands, and melanin is a pigment in the skin and hair.

Appearance, personality, and poise are crucial in the cosmetology profession, along with technical skills. A cosmetologist's look and demeanor often represent the salon and can attract clients. The statement in option b is incorrect as it contradicts the importance of a professional image in the industry.

Light makeup is suitable for a job interview as it provides a polished appearance without being overwhelming. It helps to look fresh and professional. Heavy or photographic makeup might be too much for an interview setting.

Adult fingernails generally grow at an average rate of about 1/8 inch per month. Nail growth rates can vary based on several factors, but they do not typically change drastically with the seasons.

Foundation provides the base for all other makeup products and helps to even out skin tone, creating a uniform canvas for the application of other colorful make-up products.

The fact that hair grows and sheds in a cyclical manner is a well-established truth, unlike the other myths listed.

To find the voltage (E) in Ohm's Law, the formula used is E = I x R, where I is the current and R is the resistance.

The standard diameter for wires used in convenience outlet layouts is typically 12 gauge to ensure safety and proper functioning.

Using Ohm's Law (V = I x R), the voltage required is 8 amperes × 20 ohms = 160 volts.

In a parallel connection, the total resistance is reduced, resulting in the least amount of equivalent resistance compared to series connections.

Open wiring on insulators involves the use of cleats, knobs, tubes, and flexible tubing to protect and support insulated conductors exposed in buildings.

When connected in series, the voltage is divided between the lamps, resulting in each lamp receiving less voltage and therefore producing less light.

Connecting appliances in parallel ensures that each one operates independently, and they receive the full voltage of the power supply, which is why parallel connections are preferred.

When replacing a fuse, it is crucial to use the same size and type to ensure proper protection and functioning of the electrical circuit.

The process of splitting an atom, such as uranium, is known as fission.

A photovoltaic system is a type of solar collector that generates electrical voltage when exposed to sunlight.

The photoelectric effect refers to the emission of electrons from a substance when exposed to electromagnetic radiation.

First, find the current using Power = Voltage x Current (20,000 W / 240 V = 83.3 A). Then use Ohm's Law (R = V / I) to find resistance: 240 V / 83.3 A = 2.88 ohms, but the closest answer in the options is 23.04 ohms, which likely accounts for a unit discrepancy or error in provided options.

Resistance is proportional to length. Using a ratio (60 ohms / 125 ohms) = (L / 500 meters), the length L is 240 meters.

A surface type device extends beyond the wall surface and is visible.

The smallest wire size permitted by code for wiring installations is 2.0 mm squared.

Rigid non-metallic conduit must be supported within 900 mm of each box.

Eggs act as an emulsifying agent in mayonnaise, helping to blend and stabilize the oil and vinegar.

Food should be bought from approved sources to ensure safety and wholesomeness.

The main goal of planning, food preparation, and service is to ensure the satisfaction of family members.

Baked mussels are generally considered a lower-cost dish compared to others like chicken kare-kare or seafood sinigang.

In American service, drinks are typically served from the right side of the guest.

"Mise en place" refers to the practice of preparing and organizing all ingredients and tools before starting to cook, which includes pre-heating the oven.

Whipping incorporates air into eggs and cream, increasing their volume and thickness.

The caloric value can be estimated by calculating the calories from fat (9 kcal/g), carbohydrates (4 kcal/g), and protein (4 kcal/g).

Vitamin C is water-soluble, not fat-soluble.

Providing satisfaction is more related to sensory and emotional aspects rather than physiological functions.

A septic tank is used to collect and treat wastewater from a house.

Sludge is the semi-liquid substance that accumulates at the bottom of a septic tank.

A ball valve can be easily opened or closed to control the flow of water, making it suitable for installation and troubleshooting.

The standard diameter for a pipe discharging from multiple closets is 3 inches or 75 mm.

Vise grips can be used to hold pipes securely by hand.

Excessive water consumption is not considered a good plumbing practice.

Potable water is defined as water that is safe for human consumption.

Pipes with a 0.5 inch diameter are commonly used for residential water supply lines.

A coupling is used to join two lengths of pipes together.

G.I. pipes are often available in 6-foot lengths for plumbing installations.
