[#1043] Anemometer is used to measure
Correct Answer
(B) Wind velocity
Explanation
Solution: An anemometer is an instrument that measures wind speed and wind pressure. Anemometers are important tools for meteorologists, who study weather patterns. They are also important to the work of physicists, who study the way air moves.

[#1045] The sudden fall of atmospheric pressure indicates
Correct Answer
(B) Storm
Explanation
Solution: A slowly rising atmospheric pressure, over a week or two, typically indicates settled weather that will last a long time. A sudden drop in atmospheric pressure over a few hours often forecasts an approaching storm, with heavy rain and strong winds.
