To ensure that the United States did not get drawn into another war, Congress passed a series of Neutrality Acts in the second half of the 1930s. The Neutrality Act of 1935 banned the sale of armaments to warring nations. The following year, another Neutrality Act prohibited loaning money to belligerent countries. The last piece of legislation, the Neutrality Act of 1937, forbade the transportation of weapons or passengers to belligerent nations on board American ships and also prohibited American citizens from traveling on board the ships of nations at war.

Once all-out war began between Japan and China in 1937, Roosevelt sought ways to help the Chinese that did not violate U.S. law. Since Japan did not formally declare war on China, a state of belligerency did not technically exist. Therefore, under the terms of the Neutrality Acts, America was not prevented from transporting goods to China. In 1940, the president of China, Chiang Kai-shek, was able to prevail upon Roosevelt to ship to China one hundred P-40 fighter planes and to allow American volunteers, who technically became members of the Chinese Air Force, to fly them.

War begins in europe

In 1938, the agreement reached at the Munich Conference failed to satisfy Hitler—in fact, the refusal of Britain and France to go to war over the issue infuriated the German dictator. In May of the next year, Germany and Italy formalized their military alliance with the “Pact of Steel.” On September 1, 1939, Hitler unleashed his Blitzkrieg, or “lightning war,” against Poland, using swift, surprise attacks combining infantry, tanks, and aircraft to quickly overwhelm the enemy. Britain and France had already learned from Munich that Hitler could not be trusted and that his territorial demands were insatiable. On September 3, 1939, they declared war on Germany, and the European phase of World War II began. Responding to the German invasion of Poland, Roosevelt worked with Congress to alter the Neutrality Laws to permit a policy of “Cash and Carry” in munitions for Britain and France. The legislation, passed and signed by Roosevelt in November 1939, permitted belligerents to purchase war materiel    if they could pay cash for it and arrange for its transportation on board their own ships.

When the Germans commenced their spring offensive in 1940, they defeated France in six weeks with a highly mobile and quick invasion of France, Belgium, Luxembourg, and the Netherlands. In the Far East, Japan took advantage of France’s surrender to Germany to occupy French Indochina. In response, beginning with the Export Control Act in July 1940, the United States began to embargo the shipment of various materials to Japan, starting first with aviation gasoline and machine tools, and proceeding to scrap iron and steel.

Following the surrender of France, the Battle of Britain began, as Germany proceeded to try to bomb England into submission. As the battle raged in the skies over Great Britain throughout the summer and autumn of 1940 ( [link] ), Roosevelt became increasingly concerned over England’s ability to hold out against the German juggernaut. In June 1941, Hitler broke the nonaggression pact with the Soviet Union that had given him the backing to ravage Poland and marched his armies deep into Soviet territory, where they would kill Red Army regulars and civilians by the millions until their advances were stalled and ultimately reversed by the devastating battle of Stalingrad, which took place from August 23, 1942 until February 2, 1943 when, surrounded and out of ammunition, the German 6th army surrendered.

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).
