Answers:

1.Answer: D

Elements known to be present on the lunar surface include, among others, oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminium (Al), manganese (Mn) and titanium (Ti). Among the more abundant are oxygen, iron and silicon.

2.Answer: D

On average, seawater in the world’s oceans has a salinity of approximately 3.5%, or 35 parts per thousand.

3.Answer: A

The isotope of Uranium capable of sustaining chain reaction is U235

4.Answer: B

5.Answer: (d)

A river profile is a curve which shows the slop of a river from source to mouth.A stream flowing over irregular terrain may have waterfalls, rapids and lakes along its course.Though the stream will wear away the irregularities to leave a smoothly curving profile called a graded profile.

6.Answer: C

7.Answer: A

World Environment day is celebrated worldwide on June 5.

8.Answer: A

9.Answer: (a)

Fluorine is the most reactive among all halogens. However the reactivity deceases from F2 to I2 (from top to bottom of group) may be attributed to (1) Low dissociation enthalpies (2) High electron affinities.

10.Answer: (a)

Scalars are quantities that have magnitude only; they are independent of direction. Vectors have both magnitude and direction. Momentum is the product of the mass and velocity of an object (p = mv). Momentum is a vector quantity, since it has a direction as well as a magnitude. The rest of quantities in option pressure, work and energy have magnitude but not direction.
