P=F/A so PA=F. (2.0x10^5)(.024)=4800N
F=ma (in this case a is acceleration due to gravity 9.8) F=mg 4800=9.8m
m=489.8 kg
4m=1959.2 kg
The four tires of an automobile are inflated to a gauge pressure of 2.0x10^5 Pa
The four tires on the author's car are inflated to an absolute pressure of 2.1x105 Pa. If the car has a mass of 2,150 kg, what is the contact area between each tire and the ground? answer is in cm2
1. (-/1 Points) DETAILS SERCP11 9.2.P.006. MY NOTES ASK YOUR TEACHER The four tires of an automobile are inflated to a gauge pressure of 2.2 x 105 Pa. Each tire has an area of 0.020 m2 in contact with the ground. Determine the weight of the automobile. N
The gauge pressure in each of the four tires of an automobile is 240 kPa . If each tire has a "footprint" of 150 cm2 (area touching the ground), determine the mass of the car. Express your answer to two significant figures and include the appropriate units.
The weight of your 1420 kg car is supported equally by its four tires, each inflated to a gauge pressure of 32.0 lb/in2 . What is the area of contact each tire makes with the road? If the gauge pressure is increased, does the area of contact increase, decrease, or stay the same? What gauge pressure is required to give an area of contact of 124 cm2 for each tire?
A steel-belted radial automobile tire is inflated to a gauge pressure of 2.15×10^5 Pa when the temperature is 65 °F. Later in the day, the temperature rises to 95 °F. Assuming the volume of the tire remains constant, what is the gauge pressure at the elevated temperature? [Hint: Remember that the ideal gas law uses absolute pressure.]
5. A steel-belted radial automobile tire is inflated to a gauge pressure of 1.75 10 Pa when the temperature is 61 °F. Later in the day, the temperature rises to 101 °F. Assuming the volume of the tire remains constant, what is the gauge pressure at the elevated temperature? (Hint: Remember that the ideal gas law uses absolute pressure.] Pa
5. A steel-belted radial automobile tire is inflated to a gauge pressure of 2.00 × 10 5 Pa when the temperature is 62 °F. Later in the day, the temperature rises to 101 °F. Assuming the volume of the tire remains constant, what is the gauge pressure at the elevated temperature? [Hint: Remember that the ideal gas law uses absolute pressure.]
5. A steel-belted radial automobile tire is inflated to a gauge pressure of 1.85 x 10° Pa when the temperature is 69 °F. Later in the day, the temperature rises to 96 °F. Assuming the volume of the tire remains constant, what is the gauge pressure at the elevated temperature? [Hint: Remember that the ideal gas law uses absolute pressure.] 3.01e5 Pa
5. A steel-belted radial automobile tire is inflated to a gauge pressure of 2.10 x 10° Pa when the temperature is 68 °F. Later in the day, the temperature rises to 97 °F. Assuming the volume of the tire remains constant, what is the gauge pressure at the elevated temperature? [Hint: Remember that the ideal gas law uses absolute pressure.] Ра
