In 2004, U. S. landfills emitted approximately 6,709 Gg of methane emissions and wastewater treatment plants emitted 1,758 Gg of methane. How many Tg of CO2equivalents did landfills and wastewater plants emit in 2004?

its c its is a mixture of gases

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

measuring things 1 litre of water

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
