Q1:

In troposphere (the weather domain), the temperature 't' at height 'h' above the sea level in metres is given by (where, temperature at sea level is 15°C and t is in °C.)

A t = 15 - 0.0065 h

B t = 15 + 0.0065 h

C t = 0.0035 h - 15

D t = 15 - 0.0035 h

ANS:A - t = 15 - 0.0065 h

The correct equation for the temperature 't' at height 'h' above sea level in the troposphere is: t=15−0.0065h So, the correct option is: t=15−0.0065h This equation represents the standard lapse rate in the troposphere, where the temperature decreases linearly with increasing altitude at a rate of approximately 0.0065°C per meter.
