At its widest point, the diameter of a bottlenose dolphin is 0.50 m. bottlenose dolphins are particularly sleek, having a drag coefficient of only about 0.090. a. what is the drag force acting on such a dolphin swimming at 7.5 m/s? b. using the dolphin’s diameter as its characteristic length, what is the reynolds number as it swims at this speed in 20° c water?

Let f(x) = x4- 8x2 . find the relativeextrema of this function using the second derivative test.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
