Senator Obama, too, was criticized for his lack of experience with foreign policy, a deficit he remedied by choosing experienced politician Joseph Biden as his running mate. Unlike his Republican opponent, however, Obama offered promises of “hope and change.” By sending out voter reminders on Twitter and connecting with supporters on Facebook, he was able to harness social media and take advantage of grassroots enthusiasm for his candidacy. His youthful vigor drew independents and first-time voters, and he won 95 percent of the African American vote and 44 percent of the white vote ( [link] ).

Politicking in a new century

Barack Obama’s campaign seemed to come out of nowhere to overcome the widely supported frontrunner Hillary Clinton in the Democratic primaries. Having won the nomination, Obama shot to the top with an exuberant base of youthful supporters who were encouraged and inspired by his appeal to hope and change. Behind the scenes, the Obama campaign was employing technological innovations and advances in social media to both inform and organize its base.

The Obama campaign realized early that the key to political success in the twenty-first century was to energize young voters by reaching them where they were: online. The organizing potential of platforms like Facebook, YouTube, and Twitter had never before been tapped—and they were free. The results were groundbreaking. Using these social media platforms, the Obama campaign became an organizing and fundraising machine of epic proportions. During his almost two-year-long campaign, Obama accepted 6.5 million donations, totaling $500 million. The vast majority of online donations were less than $100. This accomplishment stunned the political establishment, and they have been quick to adapt. Since 2008, nearly every political campaign has followed in Obama’s footsteps, effecting a revolution in campaigning in the United States.

Economic and healthcare reforms

Barack Obama had been elected on a platform of healthcare reform and a wave of frustration over the sinking economy. As he entered office in 2009, he set out to deal with both. Taking charge of the TARP program instituted under George W. Bush to stabilize the country’s financial institutions, Obama oversaw the distribution of some $7.77 trillion designed to help shore up the nation’s banking system. Recognizing that the economic downturn also threatened major auto manufacturers in the United States, he sought and received congressional authorization for $80 billion to help Chrysler and General Motors. The action was controversial, and some characterized it as a government takeover of industry. The money did, however, help the automakers earn a profit by 2011, reversing the trend of consistent losses that had hurt the industry since 2004. It also helped prevent layoffs and wage cuts. By 2013, the automakers had repaid over $50 billion of bailout funds. Finally, through the 2009 American Recovery and Reinvestment Act (ARRA), the Obama administration pumped almost $800 billion into the economy to stimulate economic growth and job creation.

Questions & Answers

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.

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
