Hydrostatic pressure is independent of directions.
Answer:
A) The water should be well sealed by putting a water trap between the aspirator and the sublimator to avoid water backing up and filling the sublimator as a result of sudden pressure drop.
B) Variation in water pressure could cause water to back up and fill the sublimator.
Answer:
Final velocity of the combining cars = 10m/s
combined momentum = 40000kgm/s
Explanation:
Given the following :
Mass of both colliding cars = 2000kg
Initial Velocity of car 1 (U1) = 0
Initial Velocity of car 2 (U2) = 20m/s
Combuned momentum after collision =?
This is an inelastic collision which is calculated thus :
M1U1 + M2U2 = M1V + M2V
M1U1 + M2U2 = (M1 + M2) V
Where V = "final Velocity of the colliding bodies
2000 × 0 + 2000 × 20 = (2000 + 2000) V
0 + 40000 = 4000V
V = 40000 / 4000
V = 10m/s
Therefore combined momentum = (M1 + M2) V
(2000 + 2000) 10
4000(10) = 40000kgm/s
