PV = nRT —> P = nRT/V
n = 0.250 moles of gas
R = 0.08206 L atm / mol K
T = 18 + 273 = 291 K
V = 7.50 L
P = (0.250)(0.08206)(291)/(7.50) = 7.96 atm
False. The 3 types of seismic waves are P wave, S wave and Surface wave
Answer:
Correct: B
Explanation:
The first block wont move because:
Σf=3-3=0N.
The second block will move because:
Σf:5-3=2N (direction to the right).
The third block will move because:
Σf=3N (direction to the right).
Answer:
