Q1. Average value of the upper and lower limits
Answer : Option B
Explaination / Solution:
The mid-points of the class interval is obtained by calculating the mean of the lower and the upper limits of the intervals.The mid-points of class-intervals of various class group are called mid-values. MV= (Lower limit + Upper limit) / 2.
Q2. Debtor _____ while creditors ____ during inflation
Answer : Option B
Explaination / Solution:
No Explaination.
Q3. Instantaneous velocity or simply velocity v at an instant t equals
Answer : Option A
Explaination / Solution:
Instantaneous velocity is the velocity of an object in motion at a specific point in time. This is determined similarly to average velocity, but we narrow the period of time so that it approaches zero.
The formula for instantaneous velocity is the limit as t approaches zero of the change in position over the change in t.
Mathematically,
Where x is the given function with respect to time t. The Instantaneous Velocity is expressed in m/s.
Q4. Radio waves for FM radio have a frequency about
Answer : Option A
Explaination / Solution:
No Explaination.
Q5. If y(x, t) = a sin (kx + ωt + φ ) represents a wave function then ‘k’ is
Answer : Option D
Explaination / Solution:
In the equation
y(x, t) = a sin (kx + t + )
the term with distance travelled 'x' is called angular wave number or propagation constant
Hence k is the angular wave number.
Q6. When blood clot starts contracting, a pale yellow fluid starts oozing out. Its name and composition is :
Answer : Option D
Explaination / Solution:
Plasma without the clotting factors is called serum. The clotting factors include fibrinogen and blood corpuscles.
Q7. Which of the following is an example of co-dominance?
Answer : Option A
Explaination / Solution:
Co-dominance is the phenomenon that deviates from Mendel’s law of inheritance. Both the alleles appear in offspring instead of one as in Mendel’s experiment. ABO blood grouping in human being is example of co-dominance in which both IA and IB appear simultaneously to form AB blood type.
Q8. H.O.H bond angle in water is
Answer : Option C
Explaination / Solution:
Due to presence of two lone pairs on O in H2O bond angle reduce to 104.50 from 1090.
Q9. The partial breakdown of glucose takes place in
Answer : Option B
Explaination / Solution:
Fermentation is an anaerobic breakdown of carbohydrates in which an organic molecule is the final electron acceptor. It does not involve an electron transport system.
Furthermore,: it is a partial breakdown of glucose giving a little energy, 2 net ATP's per glucose by way of substrate-level phosphorylation.
Q10. The general electronic configuration of alkali metals is
Answer : Option D
Explaination / Solution:
The general electronic configuration of alkali metals is ns1 as their outer most electron enters the S orbital and they have only on electon in their velence shell.
