Consider the flow of a fluid with viscosity  through a circular pipe. the velocity profile in the pipe is given as u(r) = umax(1 - r n /r n ), where umax is the maximum flow velocity, which occurs at the centerline; r is the radial distance from the centerline; and u(r) is the flow velocity at any position r. a) (10 points) if n=3, develop an expression for the mass flow rate through the pipe. b) (10 points) what is the average velocity in the pipe?

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

option number c is the right answer.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
