How much heat energy must be added to the gas to expand the cylinder length to 16.0 cm ?
Lapatulllka [165]

This question is incomplete, the complete question is;

A monatomic gas fills the left end of the cylinder in the following figure. At 300 K , the gas cylinder length is 14.0 cm and the spring is compressed by65.0 cm . How much heat energy must be added to the gas to expand the cylinder length to 16.0 cm ?

Answer:

the required heat energy is 16 J

Explanation:

Given the data in the question;

Lets consider the ideal gas equation;

PV = nRT

from the image, we calculate initial pressure;

Pi = ( 2000N/M × 0.06m) / 0.0008 m²

Pi = 15 × 10⁴ Pa

next we find Initial velocity

Vi = (0.0008 m²)(0.14) = 1.1 × 10⁻⁴ m²

now we find the number of moles

n = [(15 × 10⁴ Pa)(1.1 × 10⁻⁴ m²)] / 8.31 J/molK × 300K

N = 6.6 × 10⁻³ mol

next we calculate the final temperature;

Pf = ( 2000N/m × 0.08) / 0.0008 m²

Pf = 2 × 10⁵ Pa

Calculate the final Volume

Vf = (0.0008 m² × 0.16 m = 1.28 × 10⁻⁴ m³

we also determine the final temperature

T_{f} =  (2 × 10⁵ Pa × 1.28 × 10⁻⁴ m³) / 6.6 × 10⁻³ × 8.31 J/molK

T_{f}  = 466.8 K

so change in temperature ΔT

ΔT =  466.8 K - 300K = 166.8 K

we then calculate the change in thermal energy

ΔU = nCΔT

ΔU = ( 6.6 × 10⁻³ mol ) × 12.5 × 166.8K

ΔU = 13.761 J

C is the isochoric molar specific heat which is equal to 3R/2 for monoatomic

now we calculate the work done;

W = 1/2 × K( x_{i\\}² - x_{f\\}² )

W = 1/2 × ( 2000 N/m) ( 0.06² - 0.08² )

= - 2.8 J

and we then calculate the heat energy using the following expression;

Q = ΔU - W

we substitute

Q = 13.761 - (- 2.8 J)

Q = 13.761 + 2.8 J)

Q =  16 J

Therefore, the required heat energy is 16 J

An 50kg car travels at 2m/s. What is the car's Kinetic energy? <br> 100J<br> 200J<br> 50J
Evgen [1.6K]

Answer:

The answer is 100J.

Explanation:

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. In this question, the mass is equals to 50kg and the velocity is 2m/s

Now,

25kg×4m/s^2 = 100kgm/s^2 or 100J

A force of 15 newtons is used to push a box along the floor a distance of 3 meters. How much work was done?
jeka57 [31]

Answer:

<h3>The answer is 45 J</h3>

Explanation:

The work done by an object can be found by using the formula

<h3>workdone = force × distance</h3>

From the question

distance = 3 meters

force = 15 newtons

We have

workdone = 15 × 3

We have the final answer as

<h3>45 J</h3>

Hope this helps you

Answer:

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:

Court Administrator or Clerk

City or County Clerk

City Council Member

City Manager

Purchasing Manager
