A flask with a volume of 1.50 L, provided with a stopcock, contains ethane gas (C2H6) at 300 K and atmospheric pressure (1.013 × 105 Pa). The molar mass of ethane is 30.1 g/mol. The system is warmed to a temperature of 380 K, with the stopcock open to the atmosphere. The stopcock is then closed, and the flask is cooled to its original temperature. (a) What is the final pressure of the ethane in the flask? (b) Haw many grams of ethane remain in the flask?

- A construction crane with a 42m long horizontal arm carries a load of 5000kg,which is suspended from a trolley that runs along the length of the arm. Thecrane rotates with angular velocity of 0.15 s^-1 . The trolley pulls the load towards the axis of thecrane with a constant horizontal velocity of 0.2m/s relative to the arm. Determinethe magnitude and direction of the Coriolis force acting on the load due to therotation of the crane (the Earth's rotation can be neglected)arrow_forwardThe sport Hammer Throw involves a "hammer", which consists of a metal ballattached by a steel wire to a grip. For women, the mass of the ball is 4kg (themass of the steel wire and grip are negligible), and the length of the steel wire is120 cm. Calculate the magnitude of the centrifugal force that acts on the ball fora woman with 50cm long arms, who spins on the spot with an angular velocity of 4(pi)s^-1arrow_forwardAn AC voltage source is connected to an inductor with inductance 0.047 H. The voltage source provides a time-dependent voltage V across the inductor as described by V(t) = v0 sin(ωt), where v0 = 251 V and ω = 991 rad/s. a) Find the current through the inductor, in amperes with its sign, at time t = 1.9 s. b) Calculate the instantaneous power, in watts with its sign, that the inductor is absorbing at time t = 1.9 s.arrow_forward
- I need help with my physics practice problem. Can some one go through this and show all the steps detial by detail? and fill out the final table?arrow_forwardA standing wave can be created when a disturbance (wave) is trapped between two boundaries. Thus, standing sound wave can be produced when gas is confined in long narrow tube closed at both ends. In addition, standing waves can be produced in tubes with an opening at one end of the tube as well (open-closed tube). The eardrum can be modeled as an open-closed tube. The ear canal in adults is about 2.5 cm in length. Thus, what frequency ranges can occur in the ear canal that are within the range of human hearing? In other words, what is the fundamental frequency of the ear canal? The speed of sound in the warm air of the ear canal is 350 m/s. Hint: Wavelength of standing waves in open-closed tubes are given by the following: λ = 4L where m = 1,3,5,7 marrow_forwardA cardiologist reports to her patient that he radius of the left anterior descending artery of the heart has narrowed by 10.0%. What is the percent increase in the blood pressure drop across the artery that is required to maintain the normal blood flow through artery? Hint: To main normal blood flow, the blood volume flow rate must remain the same (Qnormal = Qdecreased). Poiseuille's Law gives the equation for volume flow rate of a viscous fluid. Please review Chapter 11 and continuity equation.arrow_forward
- The heart pumps blood into the aorta, which has an inner radius of 1.0 cm. The aorta feeds 32 major arteries. If the blood in the aorta travels at a speed of 28 cm/s, at approximately what average speed in units of m/s does it travel in the arteries? Assume that blood can be treated as an ideal fluid and that the arteries each have an inner radius of 0.21 cm.arrow_forwardA standing wave can be created when a disturbance (wave) is trapped between two boundaries.
