Beta decay is very complex phenomena in natural radioactive decay. There are 3 types of Beta decay.
B+ decay (Beta plus or Beta positive or positron decay):
is the conversion of a proton into a neutron plus a positron and an electron neutrino.
B- decay (Beta negative or Beta nought):
is the conversion of a neutron into a proton plus an electron and a electron antineutrino.
Note: a positron is the a positive electron or the antiparticle of the electron.

Answer:
Part a)

Part b)

Part c)

Part d)

Part e)

Explanation:
Part a)
Angular speed is given as



Part b)
Since turn table is accelerating uniformly
so we will have




Part c)
angular acceleration is given as



Part d)
When its angular speed changes to 120 rpm
then we will have


number of turns revolved is 15 times
so we have



Part e)
now for uniform acceleration we have
