To counter Soviet influence in the developing world, Kennedy supported a variety of measures. One of these was the Alliance for Progress , which collaborated with the governments of Latin American countries to promote economic growth and social stability in nations whose populations might find themselves drawn to communism. Kennedy also established the Agency for International Development to oversee the distribution of foreign aid, and he founded the Peace Corps , which recruited idealistic young people to undertake humanitarian projects in Asia, Africa, and Latin America. He hoped that by augmenting the food supply and improving healthcare and education, the U.S. government could encourage developing nations to align themselves with the United States and reject Soviet or Chinese overtures. The first group of Peace Corps volunteers departed for the four corners of the globe in 1961, serving as an instrument of “soft power” in the Cold War.

Kennedy’s various aid projects, like the Peace Corps, fit closely with his administration’s flexible response    , which Robert McNamara advocated as a better alternative to the all-or-nothing defensive strategy of mutually assured destruction favored during Eisenhower’s presidency. The plan was to develop different strategies, tactics, and even military capabilities to respond more appropriately to small or medium-sized insurgencies, and political or diplomatic crises. One component of flexible response was the Green Berets, a U.S. Army Special Forces unit trained in counterinsurgency    —the military suppression of rebel and nationalist groups in foreign nations. Much of the Kennedy administration’s new approach to defense, however, remained focused on the ability and willingness of the United States to wage both conventional and nuclear warfare, and Kennedy continued to call for increases in the American nuclear arsenal.

Cuba

Kennedy’s multifaceted approach to national defense is exemplified by his careful handling of the Communist government of Fidel Castro in Cuba. In January 1959, following the overthrow of the corrupt and dictatorial regime of Fulgencio Batista, Castro assumed leadership of the new Cuban government. The progressive reforms he began indicated that he favored Communism, and his pro-Soviet foreign policy frightened the Eisenhower administration, which asked the Central Intelligence Agency (CIA) to find a way to remove him from power. Rather than have the U.S. military invade the small island nation, less than one hundred miles from Florida, and risk the world’s criticism, the CIA instead trained a small force of Cuban exiles for the job. After landing at the Bay of Pigs on the Cuban coast, these insurgents, the CIA believed, would inspire their countrymen to rise up and topple Castro’s regime. The United States also promised air support for the invasion.

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).
