Acommercial advertisement shows a pearl falling in a bottle of shampoo. if the diameter d of the pearl is quite small and the shampoo sufficiently viscous, the drag d on the pearl is given by stokes's law, d=3πμvd where v is the speed of the pearl and μ is the fluid viscosity. show that the term on the right side of stokes's law has units of force.

Given that

D=3πμVD

We know that

Unit of μ is N.s/m²

Unit of V is m/s

Unit of D is m.

3 and π are scalar .

3πμVD  = (N.s/m²) x  (m/s)  x m= N

So we can say that right side have unit or force.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
