Test: Sources of Energy - 4 - Question 2

A fuel would be regarded as ‘environment friendly’ if

Test: Sources of Energy - 4 - Question 3

Which of the following is the potential site for harnessing tidal energy in India ?

Test: Sources of Energy - 4 - Question 4

To work properly, wind-electric generator’s need wind speeds of at least about-

Test: Sources of Energy - 4 - Question 5

Which of the following acts as control rods in Nuclear reactor ?

Detailed Solution for Test: Sources of Energy - 4 - Question 5

Cadmium rods are used as control rods as they are capable of absorbing neutrons without themselves Fissioning. Boron rods are used as control rods in nuclear  reactor to control the fission rate of uranium and plutonium.

Test: Sources of Energy - 4 - Question 6

Name any one element which is used in making solar cells.

Test: Sources of Energy - 4 - Question 7

The mass number of an isotope of an element is 295, if its nucleus has 196 neutrons. What is its atomic number ?

Detailed Solution for Test: Sources of Energy - 4 - Question 7

Atomic Number = Mass no. - No. Of neutrons
⇒ 295 - 196
⇒  99 
So, option ( a) is the correct answer.

Test: Sources of Energy - 4 - Question 8

Most of the sources of energy we use represent stored solar energy. Which of the following is not ultimately derived from the Sun’s energy ? 

Test: Sources of Energy - 4 - Question 9

What is the full from of OTEC

Test: Sources of Energy - 4 - Question 10

Statement A : Oceans serve as the most potential source of renewable energy
Statement B : Energy from nuclear fusion creates more pollution than energy from nuclear fission

Test: Sources of Energy - 4 - Question 11

Which of the following factors is responsible for blowing of wind ?

Test: Sources of Energy - 4 - Question 12

What is present contribution of hydro electric power stations to the electricity generated in India ?

Test: Sources of Energy - 4 - Question 13

Which of the following is incorrect statement regarding solar cooker? 

Test: Sources of Energy - 4 - Question 14

If the energy associated with 1amu is 931Mev than the energy associated with 3/2 amu is

Detailed Solution for Test: Sources of Energy - 4 - Question 14

1 amu energy = 931 MeV 
Therefore, 3/2 amu = [ 3/2 * 931] MeV
⇒ 1396.5 MeV 

*Multiple options can be correct
Test: Sources of Energy - 4 - Question 15

Which of the following is not present in Hydrogen Bomb.

Detailed Solution for Test: Sources of Energy - 4 - Question 15

To make a hydrogen bomb, one would still need uranium or plutonium as well as two other isotopes of hydrogen, called deuterium and tritium. The hydrogen bomb relies on fusion, the process of taking two separate atoms and putting them together to form a third atom. 

Test: Sources of Energy - 4 - Question 16

Why do we use black surfaces in solar devices ?

Test: Sources of Energy - 4 - Question 17

Lights from two different sources A and B have wavelength 0.3 micron and 0.7 micron respectively. Which one of the two light carry more energy per photon ?

Detailed Solution for Test: Sources of Energy - 4 - Question 17

Test: Sources of Energy - 4 - Question 18

Statement A : Oceans serve as the most potential source of renewable energy
Statement B : Energy from nuclear fusion creates more pollution than energy from nuclear fission

Test: Sources of Energy - 4 - Question 19

Which energy is not derived from the sun ?

Test: Sources of Energy - 4 - Question 20

A solar panel is made by combining a large member of-

Test: Sources of Energy - 4 - Question 21

The site of hydroelectric plant should be chosen carefully because it-

Test: Sources of Energy - 4 - Question 22

The conditions for producing biogas is

Detailed Solution for Test: Sources of Energy - 4 - Question 22

Biogas is produced from organic waste which biodegrades by means of bacteria in an anaerobic environment through a process of Anaerobic Digestion. It uses anaerobic digestion to recycle the organic materials (plant and animal products), turning them into biogas, which contains both energy (gas), and valuable soil products (liquids and solids). Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen. Hence the correct answer would be (A).

Test: Sources of Energy - 4 - Question 23

In addition to visible light, which other type of radiations are emitted by a 100w electric Lamp when it is glowing ?

Test: Sources of Energy - 4 - Question 24

Geothermal energy is feasible in regions that-

Test: Sources of Energy - 4 - Question 25

The mass number of elements P, Q, R are 2, 180, 235 respectively which one of them is most suitable to make a hydrogen bomb ?

Detailed Solution for Test: Sources of Energy - 4 - Question 25

A hydrogen bomb is based on nuclear fusion reactions. So, a light element P of mass number 2 is the most suitable to make it.
