Question Discussion & Solution

SRAM (static RAM) is random access memory (RAM) that retains data bits in its memory as long as power is being supplied.

Inside a dynamic RAM chip, each memory cell holds one bit of information and is made up of two parts: a transistor and a capacitor.

The correct answer is Violence.

Key Points

• Violence
  • It is defined by the World Health Organization in the WRVH as “the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, that either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment or deprivation” 

Additional Information

• Nonviolence
  • It is the personal practice of not causing harm to one's self and others under every condition.
• Hatred
  • It is an angry or resentful emotional response to certain people or ideas. 

CONCEPT:

Nuclear reactor:

• In a nuclear reactor, the energy is generated by a nuclear fission reaction.
• In a nuclear reactor, there is a concrete chamber and in this concrete chamber, there is a steel vessel. In this steel vessel, the nuclear fission reaction takes place.
• Fuel rods: Fuel rods are placed inside the steel chamber.
  • These rods are made of fissionable material. Generally, fuel rods are made of uranium-235, thorium, etc.
• Moderator: It is used to decrease the speed of fast-moving neutrons.
• Control rods: These rods are placed between the fuel rods. It is used to control the chain reaction. Control rods are generally made of cadmium.
  • The nuclear reactors are controlled by means of control rods which are made of a strongly neutron-absorbent material such as boron or cadmium (Cd).
• Coolant: It is used to absorb heat produced during the reaction.

EXPLANATION:

• Moderators are used to slow down the neutrons in order to carry out effective nuclear fission and also absorb neutrons. 
• The main reason why heavy water is used as the moderator is that it captures less number of neutrons compared to normal water Hence, option 2 is the answer. 

Crane, swan and falcon are the birds whereas frog is not a bird.

According to given conditions,

Clearly, the man is now facing West.

Hence, ‘West’ is the correct answer.
