How many liters of air are in a room that measures 10.0 ft ã 11.0 ft and has an 8.00 ft ceiling? 1 in. = 2.54 cm (exactly); 331l=10cm?

gravity

explanation:

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
