As a box is sliding down a ramp, a 10-n force of gravity is pulling the box down the ramp while a 2-n force of friction acts to stop the box. what is the net force accelerating the box down the ramp?

What happened in 2012 and how does it illustrate the importance of understanding the sun and how it works?

How have the greenhouse gasses increased from the year 2000 to 2018

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
