Answer:The binding energy of the nitrogen nucleus is .
Explanation:
Atomic mass of the nitrogen, =14.00307 amu
Number of protons, Z = 7
Number of neutrons,N = Atomic mass - number of protons
=14.0037 - 7 =7.00307
Mass of proton ,
Mass of neutron,
Binding energy =
The binding energy of the nitrogen nucleus is .
The question is partially incorrect, because nitration of <span> methyl benzoate results in generation of methyl 3-nitrobenzoate, and not methyl 2-benzoate.
This a because of the present of ester group, which deactivated benzene ring at ortho and para position. Due to this, the electrophile (NO2+) attackes on meta position.
The detailed mechanism is attached below.</span>

Answer:
Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding. Sometimes we want to reduce friction.
