The frictional force dependant on
a) Shape of the objects and nature of the fluid b) Nature of the fluid and weight of the
object c) Weight of the object and shape of the object d) Shape and size of the objects
Answers
Answer:
b. is the right answer
Explanation:
The speed of the object moving through a fluid affects the amount of friction acting against the motion of the object. More the speed, more is the friction. If the object is broad, it gives more area for the friction to act on. Thus, a streamlined body structure helps to cut through the fluid and reduce friction.
Answer:
{a} Shape of the objects and nature of the fluid
Explanation:
Fluid friction is friction that occurs when objects move across or through a fluid. Examples: Swimming – swimmer's body. and surface of water. Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. Lubricated friction is a case of fluid friction where a lubricant fluid separates two solid surfaces. Fluid friction is the force that tries to slow objects down when they move through a liquid or a gas. It's also known as "drag", or "air resistance". It depends on speed of the object with respect to fluid. It also depends on the shape of the object and the nature of the fluid. It is obvious that when objects move through fluids, they have to overcome friction acting on them.
