An apparatus like the one Cavendish used tofind G has large lead balls that are 7.3 kg inmass and small ones that are 0.065 kg. Thecenter of a large ball is separated by 0.061 mfrom the center of a small ball. The Cavendish apparatus for measuringG. As the small spheres of mass m areattracted to the large spheres of mass M,the rod between the two small spheresrotates through a small angle.Find the magnitude of the gravitationalforce between the masses if the valueof the universal gravitational constant is6.67259 × 10^−11 N m^2 /kg^2Answer in units of N.
A peregrine falcon is the fastest bird, flying at a speed of 200 mi/h. Naturehas adapted the bird to reach such a speed by placing baffles in its nose toprevent air from rushing in and slowing it down. Also, the bird’s eyes adjusttheir focus faster than the eyes of any other creature, so the falcon can focusquickly on its prey. Assume that a peregrine falcon is moving horizontally atits top speed at a height of 100 m above the ground when it brings its wingsinto its sides and begins to drop in free fall. How far will the bird fall vertically while traveling horizontally at a distance of 100 m? *Must include big six list for both x and y directions*
