Q1. According to India Vision report 2020, _____ percent literate India is paramount importance to realise the vision for the country in 2020
Answer : Option A
Explaination / Solution:
The Vision India Document envisages a 100% literacy rate to make India a developed country.
Q2. The frequency distribution of two variables is known as
Answer : Option C
Explaination / Solution:
Bivariate distribution is the combined probability distribution of two randomly different variables. Normally, these can be plotted graphically on x and y axes so their relationship can be analyzed and any relevant causal effect can be identified. This type of data analysis is useful in risk management.
Q3. To check rise in prices or inflation following measures are suggested except
Answer : Option A
Explaination / Solution:
No Explaination.
Q4. For motion with uniform acceleration, x-t graph is
Answer : Option A
Explaination / Solution:
the slope of the x-t grpah will give you velocity. So, if u=0, the slope of graph at t=0 is 0.
for u>0 case, the initial slope is +ve and for negative u, the initial slope is negative now, s = ut + 0.5at2, where acceleration=a let initial position is xo,
x=xxo+ut+0.5at2 ,
Hence you will get parabolic shapes.
Q5. Standing waves are characterized by fixed locations of zero displacement called nodes and fixed locations of maximum displacements called antinodes. The separation between two consecutive nodes or antinodes is.
Answer : Option D
Explaination / Solution:
No Explaination.
Q6. In humans, height shows a lot of variation. It is an example of
Answer : Option D
Explaination / Solution:
Height of human being is not controlled by single pair of gene. A number of genes participate to form growth hormone that actually triggers the height of individual.
Q7. A parallel plate capacitor with circular plates of radius 1 m has a capacitance of 1 . At t = 0, it is connected for charging in series with a resistor R = 1 M across a 2V battery. Calculate the magnetic field at a point P, halfway between the centre and the periphery of the plates, after t = s. (The charge on the capacitor at time t is q (t) = CV [1 – exp (–)], where the time constant τ is equal to CR.)
Answer : Option A
Explaination / Solution:
No Explaination.
Q8. Read the following :
i. The instrument used for recording heart’s electrical events is named electrocardiogram.
ii. In any ECG the part of base line between any two deflections is called interval.
iii. Abnormality in the working of heart changes wave pattern of ECG.
i. The instrument used for recording heart’s electrical events is named electrocardiogram.
ii. In any ECG the part of base line between any two deflections is called interval.
iii. Abnormality in the working of heart changes wave pattern of ECG.
Answer : Option B
Explaination / Solution:
ECG is a graphical representation of the electrical activity of the heart during a cardiac cycle.
Q9. Use of biocontrol measures will greatly reduce our dependence on
Answer : Option B
Explaination / Solution:
The use of biocontrol measures will greatly reduce our dependence on toxic chemicals and pesticides. Insects and pests are not killed in this method but kept undercontrol.
Q10. In eukaryotic organisms aerobic respiration takes place in presence of
Answer : Option C
Explaination / Solution:
Aerobic means “with air”. This type of respiration needs oxygen for it to occur so it is called aerobic respiration.
The word equation for aerobic respiration is:
Glucose + Oxygen Carbon dioxide + Water + Energy
The chemical equation is:
C6H12O6 + 6O2 6CO2 + 6H2O + 2900 kJ/mol
