It has been proposed that we could explore Mars using inflated balloons to hover just above the surface. The buoyancy of the atmosphere would keep the balloon aloft. The density of the Martian atmosphere is 0.0154 kg/m3 (although this varies with temperature). Suppose we construct these balloons of a thin but tough plastic having a density such that each square meter has a mass of 5.50 g . We inflate them with a very light gas whose mass we can neglect. What should be the radius of these balloons so they just hover above the surface of Mars? What should be the mass of these balloons so they just hover above the surface of Mars? If we released one of the balloons from part A on earth, where the atmospheric density is 1.20 kg/m3, what would be its initial acceleration assuming it was the same size as on Mars? If on Mars these balloons have five times the radius found in part A, how heavy an instrument package could they carry?

Your uncle is in the below-deck galley of his boat while you are spear fishing in the water nearby. An errant spear makes a small hole in the boat's hull, and water starts to leak into the galley. If the hole is 0.900 m below the water surface and has area 1.10 cm2 , how long does it take 10.0 L of water to leak into the boat?

It has been proposed that we could explore Mars using inflated balloons to hover just above the surface

It has been proposed that we could explore Mars using inflated balloons to hover just above the surface. The buoyancy of the atmosphere would keep the balloon aloft. The density of the Martian atmosphere is 0.0154 (although this varies with temperature). Suppose we construct these balloons of a thin but tough plastic having a density such that each square meter has a mass of 4.60. We inflate them with a very light gas whose mass we can neglect. So far...

Various methods have been proposed that could reverse self-gratification. Using the examples from the Social Value Orientation assignment, decide which method you feel would be most effective in reversing self-gratification in each case and explain why. Describe which norm (descriptive or injunctive) would be in effect in this method of reversal and explain why. You are shopping for a car and need something large enough to hold all of your possessions when you travel. You heard about a big markdown...

Your spaceship has docked at a space station above Mars. The temperature inside the space station is a carefully controlled 24 ∘C at a pressure of 735 mmHg . A balloon with a volume of 515 mL drifts into the airlock where the temperature is -83 ∘C and the pressure is 0.120 atm . What is the final volume, in milliliters, of the balloon if n remains constant and the balloon is very elastic?

Red Balloons Ltd, a Canadian supplier of military radar equipment, has just won a bid to lease the Spanish Air Force some high-end sensors for the next ten years. The first of 20 semi-annual payments of €5.3 million will be made on January 1, 2013. Assuming Red Balloons will need to convert Euros into dollars before they can pay their expenses, does this contract provide them with a long or short exposure to the Canadian Dollar? Explain. To manage their risk, Red...
