Answer:

Explanation:

grating element or slit width a = 1 x 10⁻² / 5000

= 2 x 10⁻⁶ m

angular width of first order spectral line of wavelength λ

= λ / a

for blue line angular width

= 434 x 10⁻⁹ / 2 x 10⁻⁶ radian

= 217 x 10⁻³ radian

for red line angular width

= 656 x 10⁻⁹ / 2 x 10⁻⁶ radian

= 328 x 10⁻³ radian

difference of their angular width

= 328 x 10⁻³  - 217 x 10⁻³

= 111 x 10⁻³ radian

Government & Public Administration

Jobs in the government and public administration career cluster involve planning, managing, and providing government legislative and administrative and regulatory services and related general purpose government services at the federal, state, and local levels.

This career cluster is divided into seven pathways:

Governance

National Security

Foreign Service

Planning

Revenue and Taxation

Regulation

Public Management and Administration

Governance

Officials involved in the governance pathway uphold the structure of our government. They typically work with constituents, or voters represented by elected officials; while others resolve conflicts among interest groups with opposing goals.

Sample occupations include:

Legislative Assistant

Congressional Aide

Lobbyist

County Commissioner

Senator

Representative

Mayor

Governor

Lieutenant Governor

National Security

Maintaining a strong national security encompasses such diverse activities as running a hospital, commanding a tank, programming computers, operating a nuclear reactor, or repairing and maintaining a helicopter. The military provides training and work experience in these fields and many others for more than 2.5 million people who serve in the active Army, Navy, Marine Corps, Air Force, and Coast Guard, their Reserve components, and the Air and Army National Guard.

Sample occupations include:

Combat Control Officer

Missiles and Space Systems Officer

Submarine Officer

Munitions Officer and Specialist

Infantry Officer and Specialist

Air Defense Artillery Officer

Military Intelligence Officer

Cryptographer

Intelligence Analyst

Foreign Service

People working in the Foreign Service pathway help to ensure peaceful relations between the U.S. and foreign countries. They also aid immigrants wanting to live and/or work in the U.S. These people serve mainly in embassies, consulates, diplomatic missions, and in Washington, D.C.

Sample occupations include:

Foreign Service Officer

Diplomatic Officer

Consular Officer

Ambassador

Diplomatic Courier

Planning

People who work in the Planning pathway develop long- and short-term land use plans to provide for growth and revitalization of urban, suburban, and rural communities, while helping local officials make decisions concerning social, economic, and environmental issues.

Sample occupations include:

Planner

Census Enumerator

Census Clerk

Federal Aid Coordinator

Economic Development Coordinator

Chief of Vital Statistics

Revenue and Taxation

People who work in the Revenue and Taxation pathway ensure that governments obtain revenue from businesses and citizens by collecting audits, monitoring taxes payable and collecting overdue tax dollars.

Sample occupations include:

Tax Examiner

Tax Clerk

Revenue Agent

Internal Revenue Investigator

Assessor

Auditor

Regulation

People who work in the Regulation pathway will typically possess a body of technical knowledge about an industry, the environment, or technology. This –coupled with a knowledge of related laws, rules, and regulatory systems –permit regulators to protect our health, safety, and environment as well as ensure the integrity of our financial, transportation, and public utility industries.

Sample occupations include:

Investigator/ Examiner

Code Inspector

Bank Examiner

Election Supervisor

Child Support Officer

Cargo Inspector

Border Inspector

Aviation Safety Officer

Public Management and Administration

Government agencies and public corporations and trusts have specific and rigorous standards for the stewardship of public resources. Public management careers will require technical skills related to budgeting, personnel management, procurement or other activities, and specific knowledge of the regulations and other policies that govern public management.

Sample occupations include:

Calculate delta g for the reaction if the partial pressures of the initial mixture are pcl5 = .0029 atm, pcl3 = .27 atm, and pcl
AnnyKZ [126]

Answer: equation for the reaction is given below

PCL2+PCL3=PCL5

Where pcl2=0.40atm,pcl3=0.27atm

Pcl5=0.0029atm

Using ∆G=-RTin(PCL5/PCl2*PCL3)

Where R=8.314J/K/mol and T=298K

∆G=-8.314*298in(0.0029/0.40*.27)

∆G=8962.6J/mol

Novay_Z [31]

Answer:

When a an object is been rotated its resistance capacity to that rotational force is know as rotational inertia  and this mathematically given as

          I = mr^2

   Where m is the mass

                r is the rotation radius

For the spinning of the lamp as a baton to work the location of the center of mass of the floor lamp needs to be located

This is more likely to be located closer to base of the lamp as compared to the top, so success of spinning a floor lamp like a baton is highly likely if the lamp is grabbed closer to the base because that is where the position of its center of mass is likely to be.
