Explanation:

Cathode ray is a beam of electrons emitted from the cathode of a vacuum tube. It is invisible. Cathode ray tubes are also found in televisions and computer monitors. Since cathode ray is a beam of electrons and all electrons are identical, charge to mass ratio is same for all the gases and does not depend on the nature of gas.

Read the passage carefully and choose the best answer to each question out of the four alternatives and click the button corresponding to it.

Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over million of years, these dead creatures form large deposits under seabed and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out the oxygen, thus preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rocks become thicker, and heavier. Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.

From where does mineral oil originate?

A) Complex mixture of substances	B) Carcasses of tiny animals and plants that live in the sea
C) From lakes	D) Only from plants

Answer & Explanation Answer: B) Carcasses of tiny animals and plants that live in the sea
