Answers
Answer:
1. the pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch). Barometric pressure has important effects on water chemistry and weather conditions. It affects the amount of gas that can dissolve in water.
2. Accurate weather predictions are important for planning our day-to-day activities. Farmers need information to help them plan for the planting and harvesting of their crops. ... Beyond that, detailedforecasts are less useful, since atmospheric conditions such as temperature and wind direction are very complex.
3. Wet clothes take longer time to dry on a humid day because the air has a lot of water vapour and so it can't accomodate the water vapour created by the wet clothes. So, the water remains, in the clothes for a longer time.
