A given coin has a mass of 3.0 g. Calculate the nuclear energy that would be required to separate all the neutrons and protons from each other. For simplicity assume that the coin is entirely made of `""_(29)^(63)Cu` atoms (of mass 62.92960 u).

Text Solution

Verified by Experts

`BE = [{Zm_P + (A -Z)m_N]-M} 931 MeV`
`= [29 xx 1.007825 + (63 - 29) xx 1.008665 - 62.92960] 93] = 551.38 MeV`
Number of atoms in 63 g of Cu = `6.023 xx 10^(23)`
`:. ` Number of atoms in 3g of `Cu, n = (6.023 xx 10^23)/(63) xx 3 = 0.2868095 xx 10^(23)`
`:.` The energy requierd to separate all protons and neutrons ,
`E = BE xx n = 551.38 xx 0.2868095 xx 10^(23) = 1.58 xx 10^(25) MeV`

A string of linear mass density 0.5 g cm^-1 and a total length 30 cm is tied to a fixed wall at one end and to a frictionless ring at the other end. The ring can move on a vertical rod. A wave pulse is produced on the string which moves towards the ring at a speed of 20 cm s^-1 . The pulse is symmetric about its maximum which is located at a distance of 20 cm from the end joined to the ring. (a) Assuming that the wave is reflected from the ends without loss of energy, find the time taken by the string to regain its shape. (b) The shape of the string changes periodically with time. Find this time period. (c) What is the tension in the string ?

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.
