Given:
V1 = 4m3
T1 = 290k
P1 = 475 kpa = 475000 Pa
V2 = 6.5m3
T2 = 277K
Required:
P
Solution:
n = PV/RT
n = (475000 Pa)(4m3) / (8.314 Pa-m3/mol-K)(290k)
n = 788 moles
P = nRT/V
P = (788 moles)(8.314
Pa-m3/mol-K)(277K)/(6.5m3)
P = 279,204 Pa or 279 kPa
Answer:6amperes
Explanation:
1/R=1/40 + 1/40
1/R=2/40
Cross multiplying we get
2R=40
Divide both sides by 2
2R/2 =40/2
R=20ohms
Current=voltage ➗ resistance
Current=120 ➗ 20
Current =6amperes

Answer:
Velocity (v) can be calculated via v = gt, where g represents the acceleration due to gravity and t represents time in free fall. Furthermore, the distance traveled by a falling object (d) is calculated via d = 0.5gt^2.
