Answer is: <span>the objects potential energy is 24500 J. </span>m(object) = 50 kg. h(object) = 50 m. g = 9,8 m/s². E(object) = m·g·h. E(object) = 50 kg · 9,8 m/s² · 50 m. E(object) = 24500 N·m = 24500 J = 24,5 kJ. g - <span>the acceleration of free fall. mg - </span><span>weight of the object.</span>
Bonds are polar when one element in a compound is more electronegative than the other. This creates a dipole in the molecule where one end of the molecule is partially positive and one end is partially negative
