Read the below paragraph carefully answer the question :
Case study
Poverty has many faces, which have been changing from place to place and across time and has been described in many ways. In pre-independent India, Dadabhai Naoroji was first to discuss the concept of poverty line. In post-independent India, there have been several attempts to work out a mechanism to identify the number of poor in the country. The official data on poverty is made to the public by the planning commission. It is estimated on the basis of consumption expenditure data collected by the National Sample Survey organisation. Most poverty alleviation programmes implemented are based on the perspective of the five year plans. The government has a variety of programmes to generate wage employment for the poor unskilled people living in rural area.

For the given radioactive decay \(^{298}_{94}X → ^{294}_{92}X + ^{4}_{2}ɑ + Q\) - value, binding energy per nucleon of X, Y and ɑ are a, b and c. The Q - value is equal to

If half life of a radio-active nuclide A is equal to average life of another radio-active nuclide B. Find the ratio of decay constant of A to that of B.

Find out 5^th orbit radius (in pm) of Li⁺⁺ if ground orbit radius of H-atom is 51 pm.

In a series $LR$ circuit with $X _{ L }= R$, power factor is $P _1$ If a capacitor of capacitance $C$ with $X _{ C }= X _{ L }$ is added to the circuit the power factor becomes $P_2$ The ratio of $P_1$ to $P_2$ will be :

The variation of impedance (Z) with angular frequency (w) for two electrical elements is shown in the graph given. If XL,Xc, and R are inductive reactance, capacitive reactance and resistance respectively, then

To increase the resonant frequency in seriesLCR circuit,

A dipole having dipole moment M is placed in two magnetic fields of strength B1 and B2 respectively. The dipole oscillates 60 times in 20 seconds in the \(B_1\) magnetic field and 60 oscillations in 30 seconds in the \(B_2\) magnetic field. Then find the \(\frac{B_1}{B_2}\)
