When storm clouds produce lightening and thunder, then, potential energy changes into kinectic energy.
The clouds become negatively charged,and the ground is positively charged during a storm. So there creates a potential difference between the charged clouds and the ground. And when this becomes huge so much that it over comes the electrical insulation cover of air, the electrons jump to the ground.i.e. the potential energy changes into kinetic energy.
Answer:
A separation technique to separate solids from a solution. Crystallization can be defined as the process through which the atoms/molecules of a substance arrange themselves in a well-defined three-dimensional lattice and consequently, minimize the overall energy of the system.
Explanation:
Pressure = total force/total area
Total force = 660 Newton's
Total area:
Each leg contacts the floor with an area of πr^2=π(0.025m)^2=0.002m^2.
Total contact area for all 3 legs = 0.006 m^2.
Pressure = (660N) / (0.006 m^2)
= 110,000 N/m^2 = 110,000 Pascal's.
A, both potential and kinetic energy as mechanical energy is the sum of potential and kinetic energy.
