A. the air
B. a volleyball rotating over a net
C. water in a fish tank
D. a dartboard
E. a box of tissues
Fluid friction would act against the dart if the dart comes into contact with which of the following objects?
My guess is C
Fluid includes water, air, and plasma
To determine which object would act against the dart due to fluid friction, we need to understand what fluid friction is. Fluid friction, also known as drag, is a force that opposes the motion of an object through a fluid (such as air or water).
Looking at the given options:
A. the air: Air is indeed a fluid, but the question states that fluid friction would act against the dart. In this case, fluid friction with the air would not act against the dart since the dart is moving in the air.
B. a volleyball rotating over a net: This scenario does not involve fluid friction. The volleyball rotating over a net would experience other forces like gravity and tension, but not fluid friction.
C. water in a fish tank: Water is also a fluid, and when the dart comes into contact with water, fluid friction would act against it. So, the answer is letter C.
D. a dartboard: A dartboard is not a fluid, so there would be no fluid friction acting against the dart when it comes into contact with the dartboard.
E. a box of tissues: A box of tissues is also not a fluid, so there would be no fluid friction acting against the dart when it comes into contact with a box of tissues.
Therefore, the correct answer is C. water in a fish tank.
