The density of dry air at 20°C is 1.20 g/L What is the mass of dry air, in kilograms, in a room that is 20.0 m by 12.0 m by 5.0m?
A)
1.00 X 103 kg
B)
1.016 X 105 kg
C)
1.22 X 103 kg
D)
1.44 X 103 kg

double the distance = divide strength by 4

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

+15-35=-20

going in opposite directions
