Question

The binding energy per nucleon for a deuteron and an alpha particle are x1 and x2

Answer 1

The digestive system of Branchiostoma consists of an alimentary canal and digestive glands. The alimentary canal is again divided into mouth, oral hood and buccal cavity (vestibule), pharynx or branchial sac, oesophagus, intestine and anus.

Answer 2

Answer:

Q = 4 [X1 - X2]

Explanation:

since the B.E/A is X1 for deuteron and X2 for Helium  So

(# of nucleons in H2).X1 + (# of nucleons in H2).X1 = (# of nucleons in He4).X2 + Q

i.e. 2*X1 + 2*X1 = 4*X2 +Q

or Q = 4 [ X1 - X2 ]
