Q1. A pebble of mass 0.05 kg is thrown vertically upwards. Give the direction and magnitude of the net force on the pebble, during its downward motion, Ignore air resistance
Answer : Option C
Explaination / Solution:
F = mg = 0.05 x 10 = 0.5 N downwards
Q2. What the universal law of gravitation says is that, if we assume that any two bodies in the universe attract each other with a force proportional to the product of their masses and inversely proportional to the square of the distance between them, then we can explain
Answer : Option D
Explaination / Solution:
Earth and any body pull each other towards themselves , the force applied on both of them remaining the same , but the changes in position of an object is determined by its velocity and acceleration .
Q3. Which of the following is not a part of hip bone?
Answer : Option D
Explaination / Solution:
Hip bone or pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones- ilium, ischium and pubis..
Q4. Dolly sheep is made by implanting oocyte at what stage
Answer : Option C
Explaination / Solution:
Dolly (5 July 1996 – 14 February 2003) was a female domestic sheep, and the first mammal cloned from an adult somatic cell, using the process of nuclear transfer.
Dolly had three mothers (one provided the egg, another the DNA and a third carried the cloned embryo to term). She was created using the technique of somatic cell nuclear transfer, where the cell nucleus from an adult cell is transferred into an unfertilized oocyte (developing egg cell) that has had its cell nucleus removed.
The hybrid cell is then stimulated to divide by an electric shock, and when it develops into a blastocyst it is implanted in a surrogate mother. Dolly was the first clone produced from a cell taken from an adult mammal.
Q5. In oxygen difluoride and dioxygen difluoride, the oxygen is assigned an oxidation number of
Answer : Option A
Explaination / Solution:
Oxidation state of O in OF2 is +2 and O2F2 is +1. Because the number assigned to oxygen will depend upon the bonding state of oxygen.
Q6. In India, there is rapid decline in infant mortality rate and MMR due to
Answer : Option B
Explaination / Solution:
The rapid decline in IMR and MMR is due to more attention on RCH program that provide proper immunization before and after the birth of baby providing assistance in delivery and child care, all these together result into decline in dearth of infants and mother during pregnancy.
Q7. In a three sector circular flow model the three sectors are
Answer : Option A
Explaination / Solution:
No Explaination.
Q8. For a parallel plate capacitor and a dielectric of dielectric constant K When a dielectric material is inserted between the plates while_______________ the potential difference between the plates decreases by a factor K
Answer : Option B
Explaination / Solution:
When a dielectric material is introduced in between the plates of a charged capacitor, which is disconnected from the battery, the charge remains constant, while the potential decreases by a factor K. The charge on the plates will increase if the dielectric material is slipped in between the plates of a capacitor which remain connected to the battery. In this case, the potential across the plates of the capacitor remains constant being equal to thebattery voltage.
Q9.
In the following reaction, the polymer formed is ?
Answer : Option B
Explaination / Solution:
These monomers form PHBV.
Q10. Which of the following is the strongest Lewis base?
Answer : Option A
Explaination / Solution:
Because of lower electronegativity of I
