How does the law of conservation of energy impact the amount of energy that is available on our planet?

The Law of Conservation of Energy impacts the amount of energy that is available on our planet because energy can not be created or destroyed, but it can be transformed into different categories of itself. Generally saying that the creation of energy is impossible, being that energy is itself until it gets transformed into a different category. Energy under that category can run out, therefore, more energy must be transformed into that category to replace the energy that was already yet consumed.

Which of the following are risk factors for emphysema ? correct answer : a and and c          good luck and have a nice benevolentpuppy day! : )

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
