a force of 5.25 newtons acts on an object of a mass 25.5 kilogram .how far is the object from the center of earth?(the value of G is 6.673x10-11 newtons meter2/kilogram 2. the mass of earth is 5.98x 1024 kilogram

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.
