A car driver measures a tire pressure of 220 kPa. Whatis the absolute pressure in the tire?

What is the gauge pressure of the gas in the closed tube in the figure? (Take the atmospheric pressure to be 760 mm Hg.) 200 тm Hg Open to the atmosphere (a) (b) —200 тт Hg (c) 960 тm Hg (d) 560 тm Hg 20 cm Gas- -Hg (e) —960 тт Hg

Assume patm = 1.00 atm....what is the gas pressure pgas?   express answer in pascals to three sig figures...

plz, physics , please solve question 16

Which of the following is true for the situation below? po is the atmospheric pressure, p is the density of the mercury. Pgas - Mercury 16 cm 6 ст Pgas = PO Pgas + Pg(0.06m) = PO Pgas = Po + pg(0.10m) Pgas = Po + pg(0.16m) O Pgas + Pg(0.10m) = Po %3D pgas + pg(0.16m) = Po Pgas = Po + pg(0.06m)

Soapy water has a surface tension of 0:025 N m-1. A small bubble initially of radius ?1 = 2 mm is formed. The air pressure in the vicinity of the bubble is 100 kPa. (a) What is the gauge pressure inside the bubble now Δ?2? The bubble expands to a radius of ?2 = 4 mm. (b) What is the ratio of the gauge pressures Δ?1/Δ?2? (c) What is the ratio of the bubble diameters ?1/? 2?

Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.525 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05×103 kg/m3. a. Calculate the systolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the top (and greater) number is the systolic pressure.  b. Calculate the diastolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the bottom (smaller) number is the diastolic pressure.

The basic function of an automobile's carburetor is to atomize the gasoline and mix it with air to promote rapid combustion. Assume that 40 cm? of gasoline is atomized into N spherical droplets. Each droplet has a radius of 2.0 x 10-5 m. Find the total surface area of these N spherical droplets.
