Answer:
D
Explanation:
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
Answer:
The correct answer is A. 270L
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. The conditions STP are 1 atm of pressure and 273K of temperature.
We convert the unit of pressure in mmHg into atm:
760mmHg----1 atm
450mmHg---x= (450mmHgx 1 atm)/760mmHg=0,59atm
P1xV1/T1= P2xV2/T2
V2=((P1xV1/T1)xT2)/P2
V2=((0,59atmx500L/300K)x273K)/1 atm=<em>269,407 L</em>
