Answer:
E = 7.99 *10^{-13} J
Explanation:
the given reaction is

we know that energy is given as

where
m_1 H^1 is mass of proton = 1.672622 *10^{-27}
m_1 H^2 is mass of deuterium = 3.344494 *10^{-27}
m_2 H^3 is mass of He = 5.008234 *10^{-27}
E = [1.672622 *10^{-27} + 3.344494 *10^{-27} - 5.008234 *10^{-27} ] *(3*10^8)^2
E = 7.99 *10^{-13} J
Answer :
The magnet produces a domain alignment that allows the iron become magnetic such that it is attracted to the original magnet.the magnetic iron can then create the same effect on another piece of iron.
Explanation:
the piece of magnet is brought closer to the iron where the domains of the iron align including the magnetic poles.
