) ions). Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 Â°C (39 Â°F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about â2 Â°C (28 Â°F).
How does air resistance affect the acceleration of a falling object? As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying t â¦ o limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
My assigned question is âwhat is air resistance?â What is air resistance? Air resistance is a type of fluid friction. Air resistance occurs between moving air and objects. Air resistance is an Friction slows down the movement of an object. The air resistance can be decreased when the sides of the object are rounded. How does air resistance effect our everyday lives? Air resistance can effect you in helpful ways and in unhelpful ways. For example when riding in a car because there is air and your car is a moving object air resistance is created. Air resistance (because it is pushing against your vehicle) slows you down and obviously you do not go as fast as if the air was not pushing against.
