Correct Answer: Infrared radiation
Explanation:
Infrared radiation
Correct Answer: alloy and drop-forged steel
Correct Answer: Power
Explanation:
Energy can be transferred from one system to the other. The rate at which energy is transferred from one system to other system is called POWER. Energy transferred in one second is called a watt.
Correct Answer: Violet
Explanation:
Violet colour has the highest energy. The higher the frequency, the faster the oscillations and thus the higher the energy. Therefore, the highest-frequency ultra-violet light or the lowest wavelength is violet.
Correct Answer: Earth's core contains a large amount of iron
Explanation:
In physics, the dynamo theory proposes a mechanism by which a celestial body such as Earth or a star generates a magnetic field.
Earth's crust core contains a large amount of iron and nickel is the evidence of the dynamo theory.
Correct Answer: Vitamin B7
Explanation:
Biotin is a water-soluble B vitamin, also called vitamin B7 and formerly known as vitamin H or coenzyme R.
Correct Answer: There are two types of printers we use They are * Laser Printers and * Inkjet Printers And again Laser printers are of two categories They are :: 1 Personal laser printers and 2 Office laser printers
Correct Answer: Discontinuous chips
Correct Answer: Sand and silicates
Correct Answer: 2 seconds
Explanation:
