Gravitational Acceleration inside a Planet. Consider a spherical planet of uniform density rho. The distance from the planet's center to its surface (i. e., the planet's radius) is Rp. An object is located a distance R from the center of the planet, where R A. Find an expression for the magnitude of the acceleration due to gravity, g(R), inside the planet. Express the acceleration due to gravity in terms of rho, R, π, and G, the universal gravitational constant.
B. Rewrite your result for g(R) in terms of gp, the gravitational acceleration at the surface of the planet, times a function of R.

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
