Pluto orbits the sun at an average distance of 5.91 × 10^12 meters. pluto’s diameter is 2.30 × 10^6
meters and its mass is 1.31 × 10^22 kilograms.
charon orbits pluto with their centers separated by a distance of 1.96 × 10^7 meters. charon has
a diameter of 1.21 × 10^6 meters and a mass of 1.55 × 10^21 kilograms.
calculate the magnitude of the gravitational force of attraction that pluto exerts on charon. [show all
work, including the equation and substitution with units.]

What is a good example of instantaneous speed

The ability to make things happen is also called a. heat b. force c. matter d. energy

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.
