Answer:
Its Greater potential energy because the air is high up and that makes high energy power
Explanation:
when one substance is changed into another substance,so many properties are changed.
a-physical properties
b-chemical properties
c-nuclear properties
the properties will be called physical properties if there will be change of states of matter which includes melting,boiling,sublimation etc where the substance has gone no change in chemical composition.
the property will be called chemical if there will be change in its chemical configuration and both the initial and final products are different in their structures
the property may be nuclear when there will be change in the nuclear parameters in the initial and final products. one can take an example of transmutation when atom is converted into another atom through projectiles.
200J because you multiply 20N and 10M
