DMPQ:What is the working principle of Hydrogen Bomb?

Hydrogen bombs are thermonuclearweapons which employs fusion of isotopes ofhydrogen. The result is greatly increased explosivepower when compared to single-stage fissionweapons.The energy released in a Hydrogen bombis several magnitudes higher than anAtom bomb. A fusion bomb is more sophisticated anddifficult to make, since it requires a muchhigher temperature — in the order ofmillions of degrees … Read more

DMPQ: Explain the Concepts of air breathing propulsion and re-usable launch vehicle? How these two technology can be game changer for our quest for space?

Air breathing propulsion system: In order to provide thrust by the launch vehicles propellants are used. 70% of the constituent of propellant is oxidiser.  So air breathing propulsion system utilise the atmospheric oxygen as an oxidiser to burn the fuel. Ramjet, Scramjet and Dual Mode Ramjet (DMRJ) are the three concepts of air-breathing engines which … Read more

DMPQ: What is captive breeding programme? Discuss its advantage(SCIENCE)

Captive breeding is the process of breeding animals outside of their natural environment in restricted conditions in farms, zoos or other closed facilities. The choice of individual animals that are to be part of a captive breeding population, and the mating partners within that population, are controlled by humans.

DMPQ- Mention the different Types of Sexual Reproduction.

Allogamy Allogamy occurs when the gametes which join together during fertilization come from two different individuals. The female gamete is usually in the form of an egg or ovum while the male gamete takes the form of a sperm. Both egg and sperm are cells specialized to perform the task of reproduction; each sex cell … Read more

DMPQ- Write a short note on the Aggregate Technical and Commercial losses ( AT & C) and smart meters

It is the difference between energy input units into the system and the units for which the payment is collected.ATC Loss is the actual measure of overall efficiency of the distribution business asit measures both technical as well as commercial losses. ATC Loss(%) = (Energy Input – Energy Realised)X100 The concept of Aggregate Technical & … Read more
