Shoring means to provide sideways support to the soil which prevents it to fall off

C. Sociology
D. Psychology
From the options given, the discipline that would implement experiments more in their research methodology would be (D) psychology.
Sociology’s research methodology tends to fall into the category of case studies, direct and participatory observations, and surveys. The same can be said for criminology and criminal justice. Several sub-fields of psychology tend to use experiments to determine the cause and effect relationship between two variables or more.

Rewrite this sentence using a semicolon-Someone really damaged my car yesterday. The mechanic says it'll take $500 to repair.
Someone really damaged my car yesterday; the mechanic says it'll take $500 to repair.
In this rewritten sentence, a semicolon is used to connect two related independent clauses.
The first clause "Someone really damaged my car yesterday" stands alone as a complete thought, expressing an action and providing context.
The second clause "the mechanic says it'll take $500 to repair" also stands alone as a complete thought, providing additional information about the situation.
Using a semicolon in this context indicates that the two clauses are closely related and that the second clause provides additional information or elaborates on the idea presented
in the first clause. It helps to create a smoother flow between the two clauses compared to using a period, emphasizing the connection between the ideas expressed in each clause.

The Department of Labor established a standard to define the maximum limits of exposure to lead for all workers, including a permissible exposure limit (PEL) and action level (AL). A. False B. True
Answer:
The Department of Labor established a standard to define the maximum limits of exposure to lead for all workers, including a permissible exposure limit (PEL) and action level (AL) is True
Explanation:
PEL sets the greatest worker exposure limit to lead as 50 micro-grams of lead per cubic meter of air (50µg/m^3) which is for an averaged eight-hour period. The AL, apart from of respirator use, is an airborne concentration of 30µg/m^3, for an averaged an eight-hour period. The AL is the level at which an employer must begin specific observance activities outlined in the standard protocol.
People taking part in an experiment are called variables. True False
Answer: False
Explanation: When a human takes part in an experiment, this human is called a "research participant" or a "human subject".
While is true that you may think in these humans as "variables" of some kind, this is not really the case because there is a whole different system, where you just can't do a change in your human subject as you want, so these people are not real "variables" in the experiment.
Then, the statement is false.
Consider two closed systems a and
b. System a contains 3000kj of thermal energy at 20°c ,whereas system b contains 200kj of thermal energy at 50°
c. Now the system are brought into contact with each other . Which one states the direction of any hear transfer between the two systems and how long does it takes?
True music is limited to the sounds one hears at professional musical concerts. True or False.
Answer:
False.
Explanation:
Some authors argue that music is the combination of sounds and silences in an organized manner. Let's explain with an example: A radio noise makes sounds, but not in an organized way, so it is not classified as music. This definition sounds simple and complete, but defining music is not that obvious. Can we classify a car alarm as music? It makes sounds and silences in an organized way, but I guarantee most people wouldn't call that sound music.
So what is music anyway?
In a more didactic and comprehensive way, music is all that is composed of melody, harmony and rhythm. Thus, we can say that there are several types of music and that this concept is not limited to the sounds you hear in professional music concerts.
What do physical changes do? alter the chemical structure of a substance becomes a new chemical substance increase the total mass of a substance affect the size, shape, and phase of a substance
The correct answer is D. Affect the size, shape, and phase of a substance
Explanation:
In chemistry, a physical change occurs when a substance changes its state, and other features such as color or size without changing its structure, composition or properties as it occurs in chemical changes that involve a change in composition or formation of new substances. An example of this is water that changes its state to gas if it reaches its boiling point or to ice if the temperature is reduced. However, this only changes the size, shape, and phase of water without altering its composition. Also, this change is reversible. This implies, physical changes only "affect the size, shape, and phase of a substance".
In this food web, birds would be classified as
Answer:
Omnivores
Explanation:
Omnivores refer to those organisms that are dependent on both the plants as well as animals. For example, Human beings, turtles and lizards.
Birds are also often considered to be omnivores. They are mostly dependent on the plants and their seeds, but their main source of protein is insects and worms, which most of the birds directly eat. For example, eagle, crows.
Thus, in a food web, birds are classified as omnivores.

When driving in rain the road becomes the most slippery: Just after the rain quits When the wind is blowing at least 25 mph Right after it starts to rain After it has rained for 20 minutes
After 20 minutes of rain, the road is at its most treacherous for driving. As a result, choice (D) is the appropriate response.
Why are roads sometimes extremely slippery after rain fall?After the first rainfall of the season, roads typically turn slick because of all the dust and oil particles that have not yet been swept away and are combined with the moisture. In essence, they produce a somewhat more lubricating coating between the road and the tire.
When a car begins to swerve uncontrollably because the tires are in contact with more water than their treads can move, this is known as hydroplaning. The water starts to lift the front tires off the ground slightly when traveling at high speeds over wet pavement, leaving a thin layer between the tire and the surface. The driver may lose control of the vehicle and maybe crash as a result of that film and the separation of the tire from the road.
Hence, option (D) is accurate.
