During each cycle, a heat engine ejects 75 J of thermal energy for every 115 J of input thermal energy. This engine is used to lift a 360-kg load a vertical distance of 27.0 m at a steady rate of 52.5 mm/s. How many cycles of the engine are needed to accomplish this task?

explanation:

scientific laws are the result of testing theories and proving them to be facts.

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.
