When the employer receives an OSHA citation, it must be: A. Contested and filed with the courts B. Copied and mailed to each worker C. Posted for 3 days or until the violation is fixed D. Signed and returned to OSHA

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.

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.

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.

After 20 minutes of rain, the road is at its most treacherous for driving. As a result, choice (D) is the appropriate response.

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.

Answer: All of the above

Explanation:

Excavation and trenching  is the most dangerous types of construction. Shielding helps to provide safety to the employees. It provides protection against cave ins.

The simplest form of protection is benching and shoring. where the walls of the excavation are sloped or benched. The angle to be sloped is determined by the type of soil i.e. how stable it is

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

Answer:

the answer is C

Explanation:

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 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".
