In 1994, the performer rod stewart drew over 3.0 million people to a concert in rio de janeiro, brazil. the people in the group had an average mass of 80 kg. 1. what collective gravitational force would the group have on a 5.5-kg eagle soaring 270 m above the throng? if you treat the group as a point object, you will get an upper limit for the gravitational force. (express your answer to two significant figures.)
2. what is the ratio of that force of attraction to the force between earth and the eagle? (express your answer to two significant figures.)

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
