Q1. For Geostationary Satellites
Answer : Option C
Explaination / Solution:
If there is a satellite in the equatorial plane rotating in the direction of earth’s rotation from west to east, then for an observer, on the earth, angular velocity of satellite will be
The time interval between the two consecutive appearances overhead will be,
If , i.e. satellite will appear stationary relative to earth. Such satellites are called geostationary satellites and will have a period of rotation as the period of rotation of earth i.e 24 Hrs.

Q7. The main difference between conductors, semiconductors and insulators is because of
Answer : Option C
Explaination / Solution:
Forbidden gap plays a major role for determining the electrical conductivity of material. Based on the forbidden gap materials are classified in to three types, they are :
- Insulators : The forbidden gap between the valence band and conduction band is very large in insulators. The energy gap of insulator is approximately equal to 15 electron volts (eV).
- Conductors: In a conductor, valence band and conduction band overlap each other. Therefore, there is no forbidden gap in a conductor.
- Semiconductors: In semiconductors, the forbidden gap between valence band and conduction band is very small. It has a forbidden gap of about 1 electron volt (eV).
Q8. ____ does not study individual cases
Answer : Option B
Explaination / Solution:
Statistics does not give any specific importance to the individual items; in fact it deals with an aggregate of objects
Q9. Testes are located outside the abdominal cavity in scrotum because
