A model train running on an inclined track is part of a closed system that has 316 J of mechanical energy. If the kinetic energy of the train decreases from 314 J to 250 J, what happens to the gravitational potential energy of the system?

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
