The world´s tallest elevator is actually underground, in the Mponeng Gold Mine in South Africa, reaching 2280 meters in height. Using the formula for gravitational potential energy (below), calculate how much extra gravitational potential energy the elevator will have at the top of the mine, after it collects 10 passengers from the bottom of the mine. The passengers have an average mass of 72 kg each and the lift itself has a mass of 450 kg. You can assume that gravity on earth is ~10 N/kg. *

Energy can be transformed from one form to another. the diagram shows one such process. which energy transformation is represented in the diagram? nuclear to thermal and radiant nuclear to electrical and chemical chemical to nuclear and radiant chemical to electrical and nuclear

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
