Q2.
A particle starts from the origin at t = 0 s with a velocity of 10.0 m/s and moves in the x-y plane with a constant acceleration of ( 8.0+ 2.0) m . At what time is the x- coordinate of the particle 16 m? What is the y-coordinate of the particle at that time?
Answer : Option B
Explaination / Solution:
u = uxi + uyj = 10j,
ux = 0 and uy = 10 m/s
a = axi + ayj = 8i + 2j,
ax = 8 and ay = 2 m/s2
x = uxt +axt2
=> 16 =
t = 2 sec
y = uyt + = 10x2 + = 24 m
Q3. _____ is the population density the _____ is the pressure of population on land and the more the economic problems
Answer : Option D
Explaination / Solution:
The population density of an area can greatly affect that area's economy and social conditions.
Q4. Small disc like structures that occur in the centromere are
Answer : Option A
Explaination / Solution:
Small disc-shaped structures at the surface of the centromeres are called kinetochores. These structures serve as the sites of attachment of spindle fibres (formed by the spindle fibres) to the chromosomes.
Q5. The average molecular mass of colloidal can be determined by
Answer : Option B
Explaination / Solution:
Average molecular mass of colloidal solution is determined by Osmotic Pressure measurement.

Q8. The palindromic sequence out of the given options is
Answer : Option D
Explaination / Solution:
Palindromic sequence is the sequence which reads same from left to write or from right to left. MADAM is an example of palindromic sequence.
Q9. If kidney tissues are supplied with blood low in oxygen then :
Answer : Option C
Explaination / Solution:
If Kidney tissues are supplied with blood having low oxygen in it then tubular reabsorption get stopped as energy is required for active absorption.
Q10. A thermodynamic system is taken from an original state to an intermediate state by the linear process shown in Figure. Its volume is then reduced to the original value from E to F by an isobaric process. Calculate the total work done by the gas from D to E to F
