Q4. The force acting on a freely falling body in terms of mass m and acceleration due to gravity g is

A. F =

m^{- 2}

B. F =

m^{2}

C. F = m

g^{2}

D. F = mg

Answer : Option D
Explaination / Solution:

according to newton's second law of motion F = ma here acceleration is due to gravity and is equal to g. So that for a freely falling body F = mg

Q5. Oxidation number denotes the oxidation state of an element in a compound ascertained on the basis that electron in a covalent bond belongs

A. entirely to more electronegative element

B. entirely to transition elements if present

C. entirely to more electronegative element

D. entirely to halogens in a compound

Answer : Option C
Explaination / Solution:

Oxidation number is a number assigned to an element in a compound according to some rules. This number enable us to describe oxidation-reduction reactions, and balancing redox chemical reactions. When a covalent bond forms between two atoms with different electronegativities the shared electrons in the bond lie closer to the more electronegative atom eg. HCl The oxidation number of an atom is the charge that results when the electrons in a covalent bond are assigned to the more electronegative atom. It is the charge on an atom would possess if the bonding were ionic. In HCl (above) the oxidation number for the hydrogen would be +1 and that of the Cl would be -1

Q6. Myoglobin is found to be :

i. highly abundant in muscles of whales and seals .
ii. exhibiting cooperative binding of oxygen.
iii. allowing organisms to hold their breathe longer underwater.

A. all statements are correct.

B. onlyi) and ii) are correct.

C. only i) and iii) are correct.

D. only ii) is correct.

Answer : Option C
Explaination / Solution:

Myoglobin is found to be highly abundant in muscles of whales and seals. Myoglobin being oxygen and iron binding protein allowing organisms to hold their breathe longer underwater.

Q7. Successful graft reaction can be done by

A. totipotency

B. hybridisation

C. somaclonal variation

D. Xenotransplantation

Answer : Option D
Explaination / Solution:

Xenotransplantation is the transplantation of living cells, tissues or organs from one species to another. Such cells, tissues or organs are called xenografts or xenotransplants. Successful graft reaction can be done by using Xenotransplantation to get two kinds of products from single plant.

UPSC Civil services Entrance exams General Studies test # General Science Alternating Current Prepare / Learn

Q8. If

V_{L}

V_{R}

V_{C}

, and V represent the voltage across the inductor, resistor, capacitor and the source, respectively, on the phasor diagram

V_{L}

and

V_{R}

are directed opposite to each other and

V_{C}

leads

L_{C}

by 90

^{\circ}

V_{R}

and

V_{C}

are directed opposite to each other and

V_{R}

leads

V_{C}

by 90

^{\circ}

V_{L}

and

V_{C}

are at 90

^{\circ}

to each other and

V_{R}

leads

V_{C}

by 90

^{\circ}

V_{R}

and

V_{C}

are directed opposite to each other and

V_{R}

leads

V_{C}

by 90

^{\circ}

Answer : Option D
Explaination / Solution:

In Series LCR Circuit, current is same across all elements. Since for a resistor both current and voltage are in same phase, Vc is along the same direction as current in the phasor diagram.

In capacitor voltage lags current by 900 so it is at right angle with VR and in an inductor voltage leads current by 900 so it is at right angle with VR and directly opposite to Vc
