Explanation:
physical properties are those get can measured and observed without bringing a chemical change chemical properties are those that that get observed and measured when the substance undergoes a chemical change
Potential energy due to gravity
The quantum mechanical model describes the allowed energies an electron can have. It also describes how likely it is to find the electrons in various locations around an atom's nucleus.
5-14 m/s in 3 seconds
a=vf-vi/t
a=14-5/3
a=9/3
a=3 m/s^2
1 hour = 3600 seconds.
Energy dissipated = I²Rt = 8²×20×3600 = 4608000 J
