WILL MARK BRAINLIEST A peregrine falcon dives at a pigeon. The
falcon starts downward from rest and falls
with free-fall acceleration.
If the pigeon is 77.2 m below the initial
position of the falcon, how long does the falcon
take to reach the pigeon? Assume that the
pigeon remains at rest. The acceleration of
gravity is 9.8 m/s.

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
