These changes in the format and ownership of media raise the question whether the media still operate as an independent source of information. Is it possible that corporations and CEOs now control the information flow, making profit more important than the impartial delivery of information? The reality is that media outlets, whether newspaper, television, radio, or Internet, are businesses. They have expenses and must raise revenues. Yet at the same time, we expect the media to entertain, inform, and alert us without bias. They must provide some public services, while following laws and regulations. Reconciling these goals may not always be possible.

Functions of the media

The media exist to fill a number of functions. Whether the medium is a newspaper, a radio, or a television newscast, a corporation behind the scenes must bring in revenue and pay for the cost of the product. Revenue comes from advertising and sponsors, like McDonald’s, Ford Motor Company, and other large corporations. But corporations will not pay for advertising if there are no viewers or readers. So all programs and publications need to entertain, inform, or interest the public and maintain a steady stream of consumers. In the end, what attracts viewers and advertisers is what survives.

The media are also watchdogs of society and of public officials. Some refer to the media as the fourth estate , with the branches of government being the first three estates and the media equally participating as the fourth. This role helps maintain democracy and keeps the government accountable for its actions, even if a branch of the government is reluctant to open itself to public scrutiny. As much as social scientists would like citizens to be informed and involved in politics and events, the reality is that we are not. So the media, especially journalists, keep an eye on what is happening and sounds an alarm when the public needs to pay attention.

John Zaller. 2003. “A New Standard of News Quality: Burglar Alarms for the Monitorial Citizen,” Political Communication 20, No. 2: 109–130.

The media also engages in agenda setting    , which is the act of choosing which issues or topics deserve public discussion. For example, in the early 1980s, famine in Ethiopia drew worldwide attention, which resulted in increased charitable giving to the country. Yet the famine had been going on for a long time before it was discovered by western media. Even after the discovery, it took video footage to gain the attention of the British and U.S. populations and start the aid flowing.

Suzanne Ranks, “Ethiopian Famine: How Landmark BBC Report Influenced Modern Coverage,” Guardian , 22 October 2014.
Today, numerous examples of agenda setting show how important the media are when trying to prevent further emergencies or humanitarian crises. In the spring of 2015, when the Dominican Republic was preparing to exile Haitians and undocumented (or under documented) residents, major U.S. news outlets remained silent. However, once the story had been covered several times by Al Jazeera, a state-funded broadcast company based in Qatar, ABC, the New York Times , and other network outlets followed.
Hisham Aidi, “Haitians in the Dominican Republic in Legal Limbo,” Al Jazeera , 10 April 2015.
With major network coverage came public pressure for the U.S. government to act on behalf of the Haitians.

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
