Question

What is stroke's law?

Answer 1

$\huge\mathfrak{Answer}$

The force of viscosity on a small sphere moving through a viscous fluid is given by:

Fd is the frictional force – known as Stokes' drag – acting on the interface between the fluid and the particle.

Answer 2

♡HOLA FRIEND♡

----->HERE YOUR ANSWER <----

 the frequency of luminescence excited by radiation does not exceed that of the exciting radiation. 2 : a lawin physics: the force required to move a sphere through a given viscous fluid at a low uniform velocity is directly proportional to the velocity and radius of the sphere.

a law stating that in fluorescence the wavelength of the emitted radiation is longer than that of the radiation causing it. This is not true in all cases.
