Draw a sketch and use a brief analysis based on course notes: Determine the torque necessary to impose rotation rate of 1 rotation/sec for a concentric cylinder (Couette) device. The inner cylinder is 23 mm and the outer radius is 25 cm, and the length of the cylinders is 5 cm. The fluid in the gap has viscosity of 1 Pa. s. Recall that 1 rotation is 360 degrees.

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
