Rockets can propel themselves through the nothingness of space because of two fundamental laws of physics: Newton’s Third Law and the Conservation of Linear Momentum. Both ideas are essential to understanding how nearly everything in the universe moves. When an ice skater takes off from a dead stop, she digs her blade into the ice and the ice pushes back with an equal and opposite force, sending her gliding across the rink. When a cannon is fired, the cannonball goes hurtling through the air while the cannon recoils backward in response. Both of these principles stem from the same general idea: that the universe likes to keep everything in balance.

1 . First law is contained in the second law : - there will be no acceleration in the body if no external force is applied . This means that a body at rest will remain at rest and a body at motion will remain in motion .

There are three general styles you'll find with many typefaces: italic, oblique, and small caps. Small caps are often used for headings or subheadings, to add variety to your typography if using a single typeface. Italic and oblique are often confused or used interchangeably, but are two distinct styles.

Gaurav Seth 5 years ago (2898529)

Height of second object from the ground after 2s then h₂ = 100m – 20m = 80m Now, difference in the height after 2s = h₁ – h₂= 130 – 80= 50 m
The difference in hights of the objects will remain same with time as both the objects have been dropped from rest and are falling with same acceleration i.e., (acceleration due to gravity).

ANSWER

The first crisis the lunar explorers faced came just short of moonfall. The Apollo 11 Lunar Module, code – named ‘eagle’, was still 9.5 km (6 miles) up when the vital guidance computer began flashing an alarm. It was overloading. Any second it could give up the ghost under the mounting pressure and nothing the two astronauts could do would save the mission. Emergencies were nothing new to Commander Neil Armstrong but he and his co – pilot Buzz Aldrin hadn’t even practised for this one on the ground – no one believed it could happen. Sweeping feet first towards their target, they pressed ahead as controllers on Earth waited heart – in – mouth. Racing against the computer, Eagle slowed and then pitched upright to stand on its rocket plume and gave Armstrong his first view of the landing site. The wrong one! They had overshot by four miles into unfamiliar territory and were heading straight for a football field size crater filled with boulders “the size of Volkswagens”. 2. With his fuel running out, and only a minute’s flying time left, Armstrong coolly accelerated the hovering Eagle beyond the crater, touching 88 kph (55mph). Controllers were puzzled and alarmed by the unplanned manoeuvres. Mission Director George Hale pleaded silently: “Get it down, Neil. Get it down.” The seconds ticked away. 3. “Forward, drifting right,” Aldrin said. And then, with less than 20 seconds left, came the magic word: “Contact!” 4. Armstrong spoke first: “Tranquility base here, the Eagle has landed.” His words were heard by 600 million people – a fifth of humanity. 5. About six and a half hours later, Eagle’s front door was opened and Armstrong backed out onto a small porch. He wore a €200,000 moonsuit, a sort of thermos flask capable of stopping micrometeoroids travelling 30 times faster than a rifle bullet. He carried a backpack which weighed 49 kgs and enough oxygen for a few hours. Heading down the ladder, Armstrong unveiled a €200,000 TV camera so the world could witness his first step: “That’s one small step for a man, one giant leap for mankind.” It was 3.56 am, 21 July, 1969. On the basis of your reading of the passage make notes on it in points only, using abbreviations wherever necessary. Supply a suitable title. Write a summary of the passage in 80 words.

How was the Weimar Republic organised

Posted by Aasu Yadav 5 years ago (9175157)

CBSE > Class 09 > Social Science

Gaurav Seth 5 years ago (2898529)

Germany was a powerful empire in the early years of the twentieth century. It fought the First World War (1914-1918) alongside the Austrian empire and against the Allies (England, France and Russia). The Allies were strengthened by the US entry in 1917 and won the war in November 1918.

The defeat of the Imperial Germany paved the way for democratic republic in Germany. The parliamentary parties met at the National Assembly at Weimar and established a democratic constitution with a federal structure. Universal suffrage was allowed for electing the Deputies to the German Parliament (Reichstag).

Versailles Treaty: But after the First World War, Germany was forced to accept certain terms which hurt the pride of the German people. As per the peace treaty signed at Versailles, Germany lost its overseas colonies, a tenth of its population, 13% of its territories, 75% of its iron and 26% of its coal to France, Poland, Denmark and Lithuania. To weaken its power, the Allied Powers demilitarized Germany. The War Guilt Clause forced Germany to pay compensation amounting to £6 billion. The resource rich Rhineland was occupied by the Allied armies for much of the 1920s. Because of these developments, many Germans were not happy with the Weimar Republic.
