Light falls on a pair of slits 0.00177 cm apart.The slits are 88.5 cm from the screen.Thefirst-order bright line is 1.76 cm from thecentral bright line.What is the wavelength of the light

Answers

Answer 1

The wavelength of the light is approximately 0.0890085 cm.

to find the wavelength of light in this scenario, we can use the equation for the double-slit interference pattern:

λ = (d * l) / x

where:

λ is the wavelength of light

d is the distance between the slits

l is the distance from the slits to the screen

x is the distance between the central bright line and the first-order bright line

given:

d = 0.00177 cm (slit separation)

l = 88.5 cm (distance from slits to screen)

x = 1.76 cm (distance between central and first-order bright line)

substituting these values into the equation, we get:

λ = (0.00177 cm * 88.5 cm) / 1.76 cm

calculating this expression:

λ = 0.0890085 cm .

c) Procedural laws govern the rights and obligations of people.
d) Public law governs the citizenry, but not the lawmakers themselves.

Answers

The true statement about primary sources of law in the U.S. is Option a) A contract between two parties is an example of private law.

Primary sources of law are those that establish the law itself and include constitutional law, statutory law, administrative law, and common law. Private law refers to the legal relationship between individuals and entities, and contracts between two parties are a common example of private law.

Substantive law refers to laws that create rights and obligations, while procedural laws determine how those substantive laws are enforced. Therefore, statement b) is incorrect.

Public law is concerned with the relationship between the government and its citizens, including constitutional law, administrative law, and criminal law. It is not limited to governing the citizenry and does extend to lawmakers themselves, making statement d) incorrect.

Overall, understanding the different types of primary sources of law is essential to comprehending the legal system in the U.S. and how it functions.

the ban on plea bargaining in alaska proved that dangerous offenders had previously been beating the system and that plea bargaining should be discontinued. (True or False)

Answers

The ban on plea bargaining in Alaska was actually repealed in 2005 after it was found that it had unintended consequences and was not effective in reducing crime. So the statement is False.

The ban on plea bargaining was put in place in 1975 with the goal of reducing crime and ensuring that dangerous offenders did not receive lenient sentences through plea deals. However, it was later discovered that the ban had unintended consequences, such as increasing the number of cases going to trial and putting a strain on the court system. Additionally, studies showed that the ban did not have a significant impact on reducing crime. As a result, the ban was repealed in 2005 and Alaska went back to allowing plea bargaining. It is important to note that plea bargaining is a common practice in the criminal justice system and can be effective in resolving cases quickly and efficiently. However, it should be used appropriately and not as a way to let dangerous offenders off the hook.

safety belts are required to be properly secured about which persons in an aircraft and when?

Answers

Answer:

during takeoff and landing, and while en route.

Explanation:

Safety belts are required to be properly secured around all occupants of an aircraft during takeoff, landing, and turbulent conditions. This includes both passengers and crew members.

The Federal Aviation Administration (FAA) regulations mandate that passengers must be briefed on the use of safety belts prior to takeoff and landing. The briefing should include instructions on how to properly fasten and unfasten the belt, as well as the importance of keeping it securely fastened during the entire flight.

In addition to safety belts, some aircraft may also be equipped with shoulder harnesses or other restraint systems. These may be required for certain types of aircraft or for certain phases of flight, such as during takeoff and landing. The specific requirements for safety restraints will vary depending on the type of aircraft and the applicable regulations. However, the primary goal of all safety restraint systems is to keep occupants safe and secure during the flight.

All of the following laws were instituted by Congress in part to aid in detection and punishment of fraud and illegal acts except:
A) Health Insurance Portability and Accountability Act (HIPAA) of 1996.
B) False Claims Act.
C) Healthcare Fair Reporting Act.
D) Stark Laws.

Answers

All of the laws were instituted by Congress in part to aid in the detection and punishment of fraud and illegal acts except Option C. Healthcare Fair Reporting Act.

The HIPAA of 1996 is a federal law that establishes national standards for protecting the privacy and security of personal health information. The law also includes provisions that help prevent healthcare fraud and abuse, such as requiring covered entities to report certain types of fraud to law enforcement agencies.

The False Claims Act is a federal law that imposes liability on individuals and companies that submit false or fraudulent claims to the government for payment. The law includes provisions that encourage whistleblowers to come forward with information about healthcare fraud and abuse and provides financial incentives for doing so.

The Stark Laws also known as physician self-referral laws, prohibit physicians from referring patients to certain healthcare services in which they have a financial interest. Stark Laws aim to prevent potential conflicts of interest, protect patients from unnecessary services, and prevent the misuse of healthcare resources.

The Healthcare Fair Reporting Act, on the other hand, is not a law aimed at preventing healthcare fraud and abuse. Instead, the law requires healthcare providers to report certain adverse events to the Department of Health and Human Services. The law aims to improve patient safety by identifying and addressing problems in the healthcare system, but it does not focus on detecting or punishing fraud and illegal acts.

In conclusion, all of the laws mentioned in the question were instituted by Congress to aid in the detection and punishment of fraud and illegal acts in healthcare, except for the Healthcare Fair Reporting Act. Therefore, Option C is Correct.

fill in the blank. the lucy v. zehmer case was an example of how the courts use the _________________ standard of contracting question 16 options: subjective objective dejective writing

Answers

The Lucy v. Zehmer case was an example of how the courts use the objective standard of contracting.

In the Lucy v. Zehmer case, the main issue was whether a contract was formed when Zehmer, in a seemingly joking manner, agreed to sell his farm to Lucy. The court had to determine if a contract was legally binding or not. The objective standard of contracting was applied to assess the situation.

The objective standard of contracting refers to the principle that a contract's validity is determined by analyzing the parties' external manifestations of intent rather than their internal, subjective beliefs. In other words, the court looks at what a reasonable person would understand from the parties' actions and statements, rather than focusing on their actual intentions.

In the Lucy v. Zehmer case, the court found that despite Zehmer's claims that he was joking, his actions and words would lead a reasonable person to believe that a valid contract was formed. This included writing and signing a written agreement as well as negotiating the price. Therefore, by applying the objective standard of contracting, the court ruled in favor of Lucy, concluding that a valid contract was formed between the parties.

In summary, the Lucy v. Zehmer case demonstrates the use of the objective standard of contracting to evaluate the validity of a contract by examining the parties' external actions and statements, as opposed to their subjective intentions.

Answers

Crime is offense-specific because criminals will react selectively to the characteristics of an individual criminal act. This means that criminals will take into account the specific details of a potential crime.  

Such as the type of victim, location, and potential consequences, before deciding whether or not to commit the crime. Offense-specific crime prevention strategies aim to make it harder or less desirable for criminals to commit specific types of crimes. For example, increasing lighting in high crime areas or adding security cameras to deter potential burglars. It is important for law enforcement agencies to understand the characteristics of specific criminal acts in order to develop effective prevention strategies.
