1. What is the gravitational potential energy of a ball at a heigh of 10m that has a mass of 10 kg?
a) 980 JI
b) 200 J
c) 760 J

Which of these describe conduction transfer of heat between two objects that are touching transfer of heat by the actual movement of war matter the process in which energy is imitated by one of the object transmitted through space and absorbed by another a process in which energy is released by the molecules breaking apart
