Assuming bicycle tires are perfectly flexible and support the weight of bicycle and rider by pressure alone, calculate the total area of the tires in contact with the ground if a bicycle and rider have a total mass of 80. 0 kg, and the gauge pressure in the tires is 3. 50×105 Pa. 13. 5 cm^2 22. 4 cm^2 32. 4 cm^2 10. 0 cm^2
Find the gauge and absolute pressures in the balloon and peanut jar shown in figure below, assuming the manometer connected to the balloon uses water and the manometer connected to the jar contains mercury. Express in units of centimeters of water for the balloon and millimeters of mercury for the jar, taking h = 0. 0500 m for each. (a) (b) (c)Density of water = 1. 000×103 kg/3 Density of mercury = 1. 36×104 kg/m3 Balloon: 2. 050 X 10^3 cm H2O; Jar: 820 mm Hg Balloon: 2. 050×10^3cm H2O; Jar: 710mmHg Balloon: 1. 035 X 10^3 cm H2O; Jar: 820 mm Hg Balloon: 1. 035×10∧3cmH2O; Jar: 710mmHg
A certain hydraulic system is designed to exert a force 100 times as large as the one put into it. What must be the ratio of their diameters? 1/100 1/10 1:1 1/1000
A certain hydraulic system is designed to exert a force 100 times as large as the one put into it. What must be the ratio of the area of the cylinder that is being controlled to the area of the master cylinder? 50 150 200 100
A host pours the remnants of several bottles of wine into a jug after a party. The host then inserts a cork with a 2. 00-cm diameter into the bottle, placing it in direct contact with the wine. The host is amazed when the host pounds the cork into place and the bottom of the jug (with a 14. 0-cm diameter) breaks away. Calculate the extra force exerted against the bottom if he pounded the cork with a 120-N force. 3.40×10^3 N extra force 9. 50×10^3 N extra force 7. 50×10^3 N extra force 5. 76×10^3 N extra force
