Countries like Japan where earthquakes are regular. So these important factors are downgraded to nice -to-haves behind the need of Japan structural stability. The Pacific ring of Fire and all its seismic activities are contributed to Japans strict building codes for skyscrapers and Towers. Building codes means, earthquakes proof structures are intended to withstand the earthquake.The prime example of an earthquake-ready country is Japan with its dedication to structural stability.
The gravitational potential energy: E p = m x g x h where m is the mass and h is the height; m = 50 kg, g = 9.81 m/s² , h = 40 m E p = 50 kg x 9.81 m/s² x 40 m Answer: E p = 19,620 J = 19.62 kJ
