GENERAL SCIENCE: Paper I (PART A)

- If the speed of light (3 × 10
^{8}m/s) and the mean radius of the earth (6 × 10^{3}km) are taken to be the units of speed and length respectively, then the value of the new unit of acceleration expressed in m/s2 will be- 1.5 × 10
^{10} - 50
- 0.02
- 1.2 × 10
^{5}

- 1.5 × 10

- 4
- 5
- 3
- 7

- Consider the function f (x) = x (1 + x) for x = 1,1 The function
- attains minima at x = and-
- is discontinuous in the given interval
- is negative at a few points in the given interval
- has a maximum at x =

- Which of the following distributions has the smallest variance?
- One way to determine whether a number (n) is prime or not is to divide it by numbers less than itself. The number of divisions required is
- n/2
- n and 1
- 2n
- less than n

- The top of a mountain is at an elevation of 45 from one bank of a river and at an elevation of 60 from the other bank. If the river has a width of 1 km, what is the height [in km] of the mountain?
- 3
- + 3
- sqrt (3) + 1

- On a cold day, a copper vessel feels colder to touch than a glass bowl. What is the reason for this?
- Glass does not cool down as easily as copper does
- Glass is a poor conductor of heat compared to copper
- The specific heat of glass is higher than that of copper
- Glass radiates more heat than copper does

- doubles
- halves
- becomes one-fourth
- remains the same

- They touch the ground at the same instant
- They touch the ground with the same velocity
- The cricket ball reaches before the football
- The football reaches before the cricket ball
