Hi bobbym,

The solutions #5161 and #5162 are correct. Good work, bobbym!

#5163. If the diagonal of a square is made 1.5 times, then what is the ratio of the areas of two squares?

#5164. The length and breadth of a square are increased by 40% and 30% respectively. The area of the resulting rectangle exceeds the area of the square by what percent?

Hi bobbym,

#5161. What happens to the area of a square when its side is halved?

#5162. If the area of a square increases by 69%, then the side of the square increases by what percent?

Hi bobbym,

The Answers #5259 (William Shockley) and #5260 (Lev Landau) are correct. Splendid!

#5261. Name the American physicist who received the 1969 Nobel Prize in physics for his work on the theory of elementary particles. He introduced, independently of George Zweig, the quark - constituents of all hadrons - having first identified the SU(3) flavor symmetry of hadrons. This symmetry is now understood to underlie the light quarks, extending isospin to include strangeness, a quantum number which he also discovered.

#5262. Name the Hungarian electrical engineer and physicist, most notable for inventing holography, for which he later received the 1971 Nobel Prize in Physics. Following the rapid development of lasers and a wide variety of holographic applications (e.g., art, information storage, and the recognition of patterns), he achieved acknowledged success and worldwide attention during his lifetime.

Hi bobbym,

The Answers : #5257 - Ernest Lawrence and #5258 - Percy Williams Bridgman.

The Answer #5257 is correct. Excellent, bobbym!

#5259. Name the American physicist and inventor; along with John Bardeen and Walter Houser Brattain, he co-invented the transistor, for which all three were awarded the 1956 Nobel Prize in Physics.

#5260. Name the  Soviet physicist who made fundamental contributions to many areas of theoretical physics; his accomplishments include the independent co-discovery of the density matrix method in quantum mechanics (alongside John von Neumann), the quantum mechanical theory of diamagnetism, the theory of superfluidity, the theory of second-order phase transitions. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below 2.17 K (−270.98°C).

Hi bobbym,

The Answers : #5255 - Paul Adrien Maurice Dirac and #5256 - Carl David Anderson.

The Answer #5255 is correct, bobbym! Brilliant!

#5257. Name the pioneering American nuclear scientist, winner of the Nobel Prize for Physics in 1939 for his invention of the cyclotron. He is also known for his work on uranium-isotope separation for the Manhattan Project.

#5258. Name the American physicist who won the 1946 Nobel Prize in Physics for his work on the physics of high pressures. He also wrote extensively on the scientific method and on other aspects of the philosophy of science. In 1905, he began investigating the properties of matter under high pressure. A machinery malfunction led him to modify his pressure apparatus; the result was a new device enabling him to create pressures eventually exceeding 100,000 kgf/cm² (10 GPa; 100,000 atmospheres).

Hi bobbym,

Hi bobbym,

The Answers #5251 and #5252 are correct. Marvelous!

#5253. Name the German theoretical physicist who originated quantum theory, which won him the Nobel Prize in Physics in 1918. He made many contributions to theoretical physics, but his fame rests primarily on his role as originator of the quantum theory. This theory revolutionized human understanding of atomic and subatomic processes, just as Albert Einstein’s theory of relativity revolutionized the understanding of space and time.

#5254. Name the  German physicist, and Physics Nobel Prize laureate who in 1919, won the Nobel Prize in Physics for his "discovery of the Doppler effect in canal rays and the splitting of spectral lines in electric fields".

Hi bobbym,

Hi bobbym,

#5251. Name one of the major English Romantic poets and is regarded by critics as amongst the finest lyric poets in the English language. A radical in his poetry as well as his political and social views, he did not achieve fame during his lifetime, but recognition for his poetry grew steadily following his death. He was perhaps best known for such classic poems as Ozymandias, Ode to the West Wind, To a Skylark, Music, When Soft Voices Die, The Cloud and The Masque of Anarchy.

#5252. Name the Russian professional tennis player who as of July 7, 2014 is ranked world No. 6 by the Women's Tennis Association (WTA) and is the top Russian player. A United States resident since 1994, she has won 32 WTA singles titles, including five Grand Slam singles titles. She has also won the year-end WTA Tour Championships in 2004. The WTA has ranked her world No. 1 in singles on five separate occasions, for a total of 21 weeks. She became the world No. 1 for the first time on August 22, 2005, and last held the ranking for the fifth time for four weeks from June 11, 2012 to July 8, 2012.
