A body of weight 200N falling freely attains a velocity of 10mls at a height of 30 above the ground. What is the total energy of that height?​

energy = workdone

energy =mgh

= mg=force

200×30

6000joules

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
