QUES: The SI unit of pressure is the pascal (symbol Pa), but vacuum is often measured in torrs, named for Torricelli, an early Italian physicist (1608–1647). A torr is equal to the displacement of a millimeter of mercury (mmHg) in a manometer with 1 torr equaling 133.3223684 pascals above absolute zero pressure. Vacuum is often also measured on the barometric scale or as a percentage of atmospheric pressure in bars or atmospheres. Low vacuum is often measured in millimeters of mercury (mmHg) or pascals (Pa) below standard atmospheric pressure. "Below atmospheric" means that the absolute pressure is equal to the current atmospheric pressure.

Absolute pressure  being equal to current atmospheric pressure means what?
What is the answer?
ANS: "Below atmospheric"
QUES: Clodius formed armed gangs that terrorised the city and eventually began to attack Pompey's followers, who in response funded counter-gangs formed by Titus Annius Milo. The political alliance of the triumvirate was crumbling. Domitius Ahenobarbus ran for the consulship in 55 BC promising to take Caesar's command from him. Eventually, the triumvirate was renewed at Lucca. Pompey and Crassus were promised the consulship in 55 BC, and Caesar's term as governor was extended for five years. Crassus led an ill-fated expedition with legions led by his son, Caesar's lieutenant, against the Kingdom of Parthia. This resulted in his defeat and death at the Battle of Carrhae. Finally, Pompey's wife, Julia, who was Caesar's daughter, died in childbirth. This event severed the last remaining bond between Pompey and Caesar.

Which individual ran for consul in 55 BC?
What is the answer?
ANS: Domitius Ahenobarbus
QUES: It established a colony at Jamestown, Virginia, in 1607. Two years later, a flotilla of seven ships left England under the Company's Admiral, Sir George Somers, and the new Governor of Jamestown, Sir Thomas Gates, with several hundred settlers, food and supplies to relieve the colony of Jamestown. Somers had previous experience sailing with both Sir Francis Drake and Sir Walter Raleigh. The flotilla was broken up by a storm. As the flagship, the Sea Venture, was taking on water, Somers drove it onto Bermuda's reef and gained the shores safely with smaller boats – all 150 passengers and a dog survived. (William Shakespeare's play The Tempest, in which the character Ariel refers to the "still-vex'd Bermoothes" (I.ii.229), is thought to have been inspired by William Strachey's account of this shipwreck.) They stayed 10 months, starting a new settlement and building two small ships to sail to Jamestown. The island was claimed for the English Crown, and the charter of the Virginia Company was later extended to include it.

Sir George Somers embarked on a mission to do what?
What is the answer?
ANS:
relieve the colony of Jamestown
