Answers :
1) Answer: A
Resistance- ohm
Energy – Watt
Power – Joule
2) Answer: C
Semiconductors made of pure elements, such as silicon or germanium, or compounds such as Gallium Arsenide or Cadmium Selenide.
3) Answer: A
The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed.
4) Answer: B
Any data (or) instruction entered into the memory of computer is called as Input.
5) Answer: B
Linux is the best-known and most-used open source operating system and not a computer language.
6) Answer: D
Nichrome is used in making heating elements for electric heaters and furnaces. Nichrome is best suitable and ideal material for making heating element.
7) Answer: A
Nylon,Polyester and Acrylic ignite and burns quickly as compared to cotton and can continue to burn after a flame is removed.
8) Answer: C
Stainless steel contains iron, chromium, manganese, silicon, carbon and, in many cases, significant amounts of nickel and molybdenum. These elements react with oxygen from water and air to form a very thin, stable film that consists of such corrosion products as metal oxides and hydroxides.
9) Answer: A
The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3
10) Answer: D
Nitrogen dioxide is part of a group of gaseous air pollutants produced as a result of road traffic and other fossil fuel combustion processes. It is produced by the Diesel Engine.
