The drag force for small objects (like bacteria) moving in a denser medium (like water) is determined by Stokes’ law, which reads Fs = 6πηrv, where r is the object’s radius, η is the fluid viscosity, and v is the object’s velocity.
The drag force and the object’s velocity are exactly proportional. Therefore, the drag force increases as the object’s velocity increases. For drag force, A is not always true.

According to the ratio 2:3, there are twice as many moles of gas sample 1 (n1) as there are moles of gas sample 2 (n2).

The sum of the static and dynamic pressures remains constant while the water flows through the horizontal tube in a streamline flow.

P + 1/2 (ρv2) = P/2 +1/2 (ρv12)

v1 = √(P/ρ + v2)

v2=u2+2as

v2=0+2(5)(10)

v2 = 100

v = 10 m/s

There is only one possible response because it is a numerical question.

Torricelli’s Law, which reads as follows: v = √(2gh), where v is the efflux speed, g is the acceleration caused by gravity, and h is the fluid height above the hole, provides the speed of efflux through a small hole in a large tank.

The acceleration due to gravity, or v = g = 9.8 m/s2, is equal to the speed of efflux through the hole, which is 9.8 m/s.
When we enter these values into the equation above, we obtain:
9.8 = √(2gh)
96.04 = 2gh is the result of squaring both sides of the equation.
9.5 meters is equal to 96.04 / (2g) h = 96.04 / (2 x 9.8) h.
As a result, the fluid is 4.9 meters above the hole.

The formula for the ratio of retarding force to speed (v) is (6πη r v)/v, or 6πη r.

Blood has almost the same density as water.[PAGE 137, REF PTB]Blood had an average density of 0.994 g/mL ± 0.032 g. Water’s density is commonly measured in grams per milliliter (1 g/ml) or grams per cubic centimeter (1 g/cm3).

Drag is a force acting in opposition to the relative motion of any moving object with respect to a surrounding fluid. It is also referred to as air resistance, a type of friction, fluid resistance, another type of friction, or fluid friction in fluid dynamics.

“Its density remains constant” is the right response. This is a property of a fluid that cannot be compressed. An incompressible fluid’s density remains constant regardless of temperature or pressure. This indicates that compressing or expanding an incompressible fluid will not alter its volume.
