Concept of nuclear reaction
Describe in brief the concept of nuclear reaction?
Expert
Bigger nucleus broken down to from two lighter nucleus and two or three neutrons is termed as nuclear fission which is used for making the atom bomb.
Two lighter nucleus combined to form bigger nucleus and is termed as nuclear fusion which is used for making the hydrogen bomb.
Drake equation (F. Drake; 1961): The method of estimating the number of intelligent, scientific species (that is, able to communicate with other species) in subsistence in our space. N
Write down any two elementary particles that have nearly infinite life time?
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.
Briefly explain the procedure to define the Specific Gravity?
Defining Aberration: The obvious change in the position of a light-emitting object due to the fidelity of the speed of light and the
The molecules of many dielectrics possess an electric dipole moment without having an external electric field. In such molecules centres of their positive and negative charges are displaced with respect to each other and therefore form a dipole. Such materials are kno
Explain Superposition principle and their illustrations? Superposition principle: The common idea that, whenever a number of influences are performing on a syst
Tesla: T (after N. Tesla, 1870-1943): The derived SI unit of the magnetic flux density stated as the magnetic flux density of a magnetic flux of 1 Wb via an area of 1 m2; it therefore has units of Wb/m2.
Write a short note on diffuse reflection?
When one coil of a magnetically coupled pair has a current of 5.0A, the resulting fluxes Φ11 and Φ21 are 0.2mWb and 0.4mWb, respectively. If the turns are N1 = 500 and N2 = 1500, find L1, L2, M and the coeffici
