Matter has weight and takes up space. You know that air takes up space, because when you breath in, your lungs fill with air and expand. :) MoMMy.!
The average human normally takes in about 35 lbs of air per day.
A curved path followed by a projectile is called a trajectory. This is the path that an object takes when it is thrown or launched into the air.
No. It is more instinctive for to breath through our noses because where far more air can get from the harmful substances in the air that us. Plus it takes less effort than breathing through your mouth

This is a ventilation system question. The return air path is the route (usually through ducting but could be through some other route such as a window or vent) that the air takes. Typically a building ventilation system would have both supply and extract systems. The return air path is this.
When you breath in the air goes through your mouth or nose and travels into your heart. Your Cardiac muscles divide the air and takes it where it needs to go.
Its breath of fresh air.
The curved path an object takes when it is thrown is called a projectile motion. It is influenced by both the initial velocity of the object and the force of gravity acting on it. The shape of the path is typically parabolic.
