Q1. The vector product of two vectors a and b is a vector c such c is perpendicular to the plane containing a and b and the direction is given by is given by
Answer : Option C
Explaination / Solution:
If vectors A and B lie in the plane of this page, the vector C will be perpendicular to this plane.
The sense (upward or downward) of the direction of the vector product is given by the direction of the advance of the tip of a right-handed screw when rotated from A to B through angle between them, the screw being placed with its axis perpendicular to the plane containing the two vectors.

Q3. Digital weighing balance uses
Answer : Option D
Explaination / Solution:
A force transducer is also known as a force sensor this converts an input mechanical force into output electrical signal.Hence a force transducer is used in digital weighing balance.
Q4. When two parents participate in reproductive process and also involve fusion of their gametes, it is called
Answer : Option C
Explaination / Solution:
In sexual reproduction male and female gametes are produced by male and female organism. The fusion of gametes results into zygote formation that finally develops as new offspring.

Q7.
For a reaction; pA +qB products, the rate law expression is
Answer : Option B
Explaination / Solution:
Order of a reaction is experimentally determined quantity. It may or may not be equal to stoichiometric coefficients.
Q8. Formula for calculating adjusted frequency is
Answer : Option A
Explaination / Solution:
Adjusted frequency of a class may be defined as the product of the frequency of corresponding class and the ratio of minimum class size to the class size.
We use the concept of adjusted frequency distribution to draw histogram of the class intervals of different width. Using it the frequency of the class intervals are adjusted in order to make the frequencies of the each class intervals and the area of the corresponding bar representing the histogram of class intervals in equal proportion.
Q9. Operation flood started in
Answer : Option C
Explaination / Solution:
Operation Flood was started by National Dairy Development Board (NDDB) in 1970s
Q10. In animal cells, the mitotic division is seen in
Answer : Option B
Explaination / Solution:
In animals, mitotic cell division is only seen in the diploid somatic cell since mitosis produces cells with same number of chromosomes as that of parents.
