One indicator of a declining economy is a continued decline in birth rates. In 2010, birth rates in Europe were at an all-time low, with the average number of children that a women has in her lifetime at well below two. In the figure above, f(t) represents birth rates for Portugal between 1960 and 2010, and g(t) represents birth in Slovakia for the same time period. For which value (s) of t is f(t)gtg(t) ?

Viscosity is the property of fluid by virtue of which fluid offers resistance to deformation under the influence of a tangential force. In the given figure as the the plate moves the fluid particle at the surface moves from position 1 to 2 and so on, but particles at the bottom boundry remain stationary. if the gap between palte and bottom boundary is small, fluid particles in between plate and bottom moves with velocities as shown by linear velocity distribution curve otherwise the velocity distribution may be parabolic. As per Newton's law of viscity the tangential force is related to time rate of deformation - (F)/(A) alpha (d' theta)/(dt) but y = (d' theta)/(dt) = u, (d' theta)/(dt) = (u)/(y) then F = eta A(u)/(y), eta = coefficient of viscosity for non-linear velocity distribution - F = eta A(du)/(dy) where (u)/(y) or (du)/(dy) is known as velocity gradiant. The velocity gradient just below the plate, in above problem is equal to - (per second)
