QUES: Two inland ports on rivers serve Oklahoma: the Port of Muskogee and the Tulsa Port of Catoosa. The only port handling international cargo in the state, the Tulsa Port of Catoosa is the most inland ocean-going port in the nation and ships over two million tons of cargo each year. Both ports are located on the McClellan-Kerr Arkansas River Navigation System, which connects barge traffic from Tulsa and Muskogee to the Mississippi River via the Verdigris and Arkansas rivers, contributing to one of the busiest waterways in the world.
How many tons of cargo does the Tulsa Port of Catoosa ship annually?

ANS: over two million

QUES: Polarization is the sum of the E-plane orientations over time projected onto an imaginary plane perpendicular to the direction of motion of the radio wave. In the most general case, polarization is elliptical, meaning that the polarization of the radio waves varies over time. Two special cases are linear polarization (the ellipse collapses into a line) as we have discussed above, and circular polarization (in which the two axes of the ellipse are equal). In linear polarization the electric field of the radio wave oscillates back and forth along one direction; this can be affected by the mounting of the antenna but usually the desired direction is either horizontal or vertical polarization. In circular polarization, the electric field (and magnetic field) of the radio wave rotates at the radio frequency circularly around the axis of propagation. Circular or elliptically polarized radio waves are designated as right-handed or left-handed using the "thumb in the direction of the propagation" rule. Note that for circular polarization, optical researchers use the opposite right hand rule from the one used by radio engineers.
What is the imagenary plane perpindicular to?

ANS: radio wave

QUES: The UK political system, while technically a multi-party system, has functioned generally as a two-party (sometimes called a "two-and-a-half party") system; since the 1920s the two largest political parties have been the Conservative Party and the Labour Party. Before the Labour Party rose in British politics the Liberal Party was the other major political party along with the Conservatives. Though coalition and minority governments have been an occasional feature of parliamentary politics, the first-past-the-post electoral system used for general elections tends to maintain the dominance of these two parties, though each has in the past century relied upon a third party to deliver a working majority in Parliament. (A plurality voting system usually leads to a two-party system, a relationship described by Maurice Duverger and known as Duverger's Law.) There are also numerous other parties that hold or have held a number of seats in Parliament.
What has the UK political system functioned as?

ANS: a two-party (sometimes called a "two-and-a-half party") system

QUES: In Greece, copper was known by the name chalkos (χαλκός). It was an important resource for the Romans, Greeks and other ancient peoples. In Roman times, it was known as aes Cyprium, aes being the generic Latin term for copper alloys and Cyprium from Cyprus, where much copper was mined. The phrase was simplified to cuprum, hence the English copper. Aphrodite and Venus represented copper in mythology and alchemy, because of its lustrous beauty, its ancient use in producing mirrors, and its association with Cyprus, which was sacred to the goddess. The seven heavenly bodies known to the ancients were associated with the seven metals known in antiquity, and Venus was assigned to copper.
What is the Greek goddess that symbolizes copper?

ANS:
Aphrodite
