The Four Forces That Influence Wind Speed & Wind Direction
Explanation:
Answer:
The size of the container needed is 1,03 liters
Explanation:
We use the formula PV=nRT. The STP conditions correspond to 1 atm of pressure and 273 K of temperature.
PV=nRT V=(nRT)/P
V= (0,0459 mol x 0,082 l atm/ K mol x 273K)/1 atm= 1,0275174 liters
Answer:
E=7
F=8
G=6
H=5
Explanation:
E: On the graph, the speed goes up and accelerating means to go faster or up.
F: (same as E but opposite)
G: The line is not going nor up or down because your speed is staying constant.
H: Nothing is on the Graph because you are not moving at all.
Hope this helps you!
