CSIR NET Earth Science Mock Test - 5 - Question 1
Save

Which physical property of the medium governs the response of Ground Penetrating Radar (GPR)?

CSIR NET Earth Science Mock Test - 5 - Question 2
Save

What is the equation of the line which passes through the point (1, -2) and is perpendicular to the line 2x - y + 3 = 0?

Detailed Solution: Question 2

Slope of the line 2x - y + 3 = 0 is 2
Product of slopes of perpendicular lines is -1
slope of required line = -1/2
-1/2(x - 1) = y + 2
-x + 1 = 2y + 4
x + 2y + 3 = 0

A river channel widens downstream because:

Detailed Solution: Question 13

A river channel widens downstream because the gradient decreases and discharge increases.

The cross-sectional shape varies with position in the stream, and discharge. The deepest part of the channel occurs where the stream velocity is the highest. Both width and depth increase downstream because discharge increases downstream. As discharge increases the cross-sectional shape will change, with the stream becoming deeper and wider.
