A nucleus is at rest in the labortory frame of reference show that if it disintegrates into two smaller nuclei . The products must be emitted in opposite directions .

Text Solution

Verified by Experts

Let `m_1 : m_2` are be the masses of product and `v_1 , v_2` are the velocities of it .
`therefore ` linear momentum after distantegration `- m_1 v_1 + m_2 +v_2`
Before .According to the principle of conservation of linear momentum
`m_1 v_1 + m_2 v_2 =0`
` V_2= -(m_1V_1)/(m_2)`

An object may be regarded to be rest or in motion depending on the frame of reference chosen to view the object. Because of length contraction it would mean that the same rod may have two dfferent lenghts depending on the state of the observe. Is this true ?

(Bi)_212^83 can disintegrate either by emitting an alpha -particle or by emitting a beta -particle. (a) write the two equations showing the products of the decays. (b) The probabilities of disintergration by alpha and beta -decays are in the ratio 7/13. The overall half-life of Bi^212 is one hour. If 1 g pure Bi^212 is taken at 12.00 noon,what will be the composition of this sample at 1 p.m the same day?

A plant breeder developed a hybrid sugarcane by grafting two differents varieties with desirable characters.

In a fusion reactor, the reaction occurs in two stages. (i) Two deuterium (""_(1)^(2)D) nuclei fuse to form a tritium (""_(1)^(3)T) nucleus with a proton as product. (ii) A tritium nucleus fuses with another deuterium nucleus to form a helium (""_(2)^(4)He) nucleus with neutron as another product. Find (a) the energy released in each stage. (b) the energy released in the combined reaction per deuterium and (c) what percentage of the mass energy of the initial deuterium is released? Given : ""_(1)^(2)D=2.014102u,""_(1)^(3)T=3.016049u,""_(2)^(4)He=4.002603u,""_(1)^(1)H=1.007825u,""_(0)^(1)n=1.008665u Take 1u = 931 MeV
