The partial pressure of the O2 is 36.3 kiloPascal when the air pressure in the mask is 110 kiloPascal based on the isotherm relation. This problem can be solved by using the isotherm relation equation which stated as Vx/Vtot = px/ptot, where V represents volume, p represents the pressure, x represents the partial gas, and tot represents the total gas<span>. Calculation: 33/100 = px/110 --> px = 36.3</span>
Answer:
Your answer should be B. a parabola.
Explanation:
The substance is an element
Answer
given,
mass of the box = 9.1 kg
kinetic friction coefficient = 0.375
acceleration = 1.69 m/s²
kinetic frictional force on the box = ?
If the elevator is stationary, the kinetic frictional force is
F = µ m g
F = 0.375 × 9.1 × 9.81
F = 33.48 N.
If the elevator is accelerating upward at 1.88 m/s^2, we add the acceleration to the acceleration due to gravity. The force is
F = µ m (g+a)
F = 0.375 x 9.1 x (9.81 + 1.69)
F = 0.375 x 9.1 x 11.5
F= 42.31 N
If the elevator is accelerating downward, we subtract.
F = µ m (g-a)
F = 0.375 x 9.1 x (9.81 - 1.69)
F = 0.375 x 9.1 x 8.12
F= 27.71 N
