A) he may increase his speed	B) his weight may be reduced
C) necessary centripetal force may be available from the horizontal component of the normal reaction due to the track to maintain the curved motion.	D) no frictional force may be produced between the wheels and the axle

Answer & Explanation Answer: C) necessary centripetal force may be available from the horizontal component of the normal reaction due to the track to maintain the curved motion.

Q:

The Kinetic energy of gas molecules

A) is unaffected by temperature variations	B) decreases with increase of temperature
C) increases with decrease of temperature	D) increases with increase of temperature

Answer & Explanation Answer: D) increases with increase of temperature

Explanation:

Kinetic Energy $K . E = \frac{1}{2} m V^{2}$ or

$K . E \propto V^{2}$ , Where 'm' is the mass and 'v' is the velocity of molecules.

Velocity is proportional to temperature. Hence, KE is proportional to temperature and would increase with temperature.

Q:

Sumanth walks 200 feet straight from his house, which is facing north and then he walks 100 feet in reverse direction.Further he takes a left turn and walks 300 yards.In Which direction is Sumanth now from his original position?

A) South-East	B) North-East
C) South-West	D) North-West

Answer & Explanation Answer: B) North-East

Explanation:

Starting From his house, Sumanth walks 200 feet straight towards North; we can write it as $N_{200}$ . Similarly, the other distances and directions can be considered and written as follows : (Notice that he covers 300 yards towards East; one yard = 3 feet and hence 300 yards = 900 feet)

$N_{200} S_{100} E_{900}$ Adding all south and all North distances and finding the net result, and also adding all East and all West distances and finding the net result, this can further be summarized as : $N_{100} E_{900}$

Thus, the direction from his original position is North-East.

A) East	B) South
C) Southwest	D) Southeast

Answer & Explanation Answer: B) South

Explanation:

Starting from the initial point facing north, the horse turns 90 degrees clockwise, which means it turns towards East. Similarly, the other directions can be considered and written as : EWS Thus, the direction it is facing now is South.

Q:

A mixture of 150 liters of wine and water contains 20% water. How much more water should be added so that water becomes 25% of the new mixture?

A) 10 liters	B) 20 liters
C) 30 liters	D) 40 liters

Answer & Explanation Answer: A) 10 liters

Explanation:

Number of liters of water in 125 liters of the mixture = 20% of 150 = 1/5 of 150 = 30 liters

Let us Assume that another 'P' liters of water are added to the mixture to make water 25% of the new mixture. So, the total amount of water becomes (30 + P) and the total volume of the mixture becomes (150 + P)

Thus, (30 + P) = 25% of (150 + P)

Solving, we get P = 10 liters
