What happens to friction if the velocity is constant? What will it equal to and what formula can be used to find it? Is it Fn = Ff?

If the velocity is constant there is no friction it will equal to zero. It is Fn=Ff

Explanation:

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

d. air pressure decreases as altitude increases.
