Answer:

49 m/s        

Explanation:

Given :

Time, t = 5 seconds

The vice falls from rest, therefore the initial velocity, u = 0.

We know acceleration due to gravity, g = 9.8 m/s2

Therefore, from equation of motion , we get

v = u + g.t

 = 0 + (9.8 x 5)

  = 49 m/s

Therefore the speed of the vice is 49 m/s after 5 second.

Which federal regulation or law governs how researchers can obtain data about subjects' disciplinary status in school from acade
morpeh [17]

The law or federal regulation which governs how scholars can gain data about subjects’ disciplinary status in school from academic records is the Family Educational Rights and Privacy Act or so-called FERPA. FERPA is a federal law that defends the confidentiality of student education information in all schools that obtain funds under a valid program of the U.S. Department of Education.

 

EXPLANATION:

FERPA gives certain rights to parents regarding the educational records of their children. These rights are transferred to the students when they reach the age of 18 or study in a school outside the high school level. Students who have been transferred are "eligible students."

 

1. Eligible students or parents have the right to check and review the records of student’s education upheld by the school. Schools are not needed to provide duplicates of the records unless, for motives such as great distance, eligible students or parents can't review the records. Schools may allege fees for duplicates.

2. Eligible students or parents have the right to ask schools to rectify records that they believe are misleading or inaccurate. If the school agrees not to change records, the qualified student or parent then has the privilege of a formal trial. After the trial, if the school still chooses not to change the records, the qualified student or parent has the right to set a statement with the record expressing their views on the information contested.

3. In general, schools must have written consent from eligible students or parents to extract any data from the records of student’s education. However, FERPA enables schools to acknowledge the records, without consent, to these parties or under the following circumstances (34 CFR § 99.31):

 

 

• School officials with lawful educational interests;

• Other schools where students are transferred;

• Stated officers for evaluation purposes or audit;

• suitable parties about financial assistance to students;

• Organizations undertaking specific studies for or on behalf of schools;

• accrediting organizations;

• To comply with a court order or subpoena issued legally;

• suitable officials in circumstances of health and safety emergencies; and

• State and local authorities, in the juvenile justice system, comply with certain state laws.
