The surface area of a balloon which depends on the amount of air inside is 2 square meters?
Area(air) = 2
The purpose of the nasal conchae is to to enhance the air turbulence in the cavity and to increase the mucosal surface area exposed to the air?
yes
Flat surface that extends indefinitely in all directions?
It is a plane that extends indefinitely in all directions. It is very easy to remember just think about what flys in the air and needs to land on a "flat surface that extends indefinitely in all directions" (the ground).
Why does a catapult shoot best from a 45 degree angle?
The [horizontal] range of a projectile is maximised when it shoots at a 45 degree angle. This is true if air resistance is ignored so that the only force acting on the projectile is gravity.
When air is warm, it rises and leaves an area of low pressure which becomes filled with sinking cold air. After a hot, sunny day, the land cools faster than the sea. What is likely to happen after a hot, sunny day on the sea shore?

What is the link between air resistance and surface area?
Air resistance is directly proportional to the surface area of an object. As the surface area of an object increases, there is more contact with air molecules, resulting in greater air resistance. This resistance can affect the speed and motion of the object.
What features of an object will affect air resistance?
The shape of the object, its surface area, and its speed through the air will affect air resistance. Objects with a more streamlined shape and smaller surface area will experience less air resistance than those with bulkier shapes and larger surface areas. Additionally, objects moving at higher speeds will experience greater air resistance.
does surface area affect terminal velocity?
Yes, surface area does affect terminal velocity. Objects with a larger surface area experience more air resistance, which can slow them down more effectively than objects with a smaller surface area. This can impact the terminal velocity, which is the maximum speed an object can reach when the force of air resistance equals the force of gravity.
What three factors affect the amount of air resistance acting on a object?
The factors that affect the amount of air resistance acting on an object are the speed of the object, the surface area exposed to the air, and the shape of the object. A faster object experiences more air resistance than a slower one, a larger surface area increases air resistance, and a streamlined shape reduces air resistance.
What are the factors that effect air resistance?
The factors that affect air resistance include the speed of the object (higher speed leads to greater air resistance), the surface area of the object (larger surface area experiences more air resistance), the shape of the object (streamlined shapes experience less air resistance), and the air density (higher air density increases resistance).
How is surface area related to air resistance?
Surface area is directly proportional to air resistance. The larger the surface area of an object, the greater the air resistance it experiences as it moves through the air. This is because a larger surface area creates more friction between the object and the air particles, slowing down its movement.
What variables affect air resistance?
The variables that affect air resistance include the speed of an object moving through the air, the surface area and shape of the object, the density of the air, and the viscosity of the air. Additionally, factors such as the altitude of the object and any obstacles in its path can also influence air resistance.
How does the shape of a parachute affect the drop time at which it falls to the ground?
The shape of a parachute can affect the drop time by influencing air resistance. A larger surface area or a more streamlined shape can increase air resistance, slowing down the descent. Conversely, a smaller surface area or more irregular shape can reduce air resistance, leading to a quicker descent.
How does changing the shape of an object affect the friction and air resistance?
Changing the shape of an object can affect friction and air resistance. For friction, the surface area in contact with another surface can increase or decrease, altering the friction force. For air resistance, a more streamlined shape will experience less resistance compared to a less streamlined shape due to differences in how air flows around the object.
How is it air resistance related to the surface area of an object?
Air resistance is directly related to the surface area of an object - the larger the surface area, the greater the air resistance encountered by the object as it moves through the air. This is because more surface area means more air molecules coming into contact with the object, resulting in a greater force opposing the object's motion.
Why does decreasing the surface area of a piece of paper decreases its air resistance when it is dropped in the air?
Decreasing the surface area of the paper reduces the amount of material exposed to the air, resulting in less air resistance. Air resistance is dependent on the surface area of the object in contact with the air, so decreasing the surface area will decrease the force opposing the paper's fall.
What is air resistance affected by?
Air resistance is affected by the speed of the object moving through the air, the cross-sectional area of the object, the density of the air, and the shape of the object. Objects with larger surface areas and higher speeds experience greater air resistance.
