Human Metabolism

Being described as the most complicated machine ever encountered by humans, the human body and the cell metabolism is nothing less than a wonder. Metabolism is the set of life-sustaining chemical reactions within organisms.

Cephalopods, such as octopi and squids, can use a form of jet propulsion to move quickly through the water. This technique of locomotion is useful in providing short bursts of speed to catch prey and to avoid predators, and it gives them the title of fastest marine invertebrates. Oxygenated water is taken in by the cephalopod and then expelled by muscular contraction through an opening called the hyponome. Assume a 5.0 kg squid draws in 0.44 kg of water and then quickly (in 0.12 s) expels this water at a speed of 10.1 m/s. What is the recoil speed of the squid just after the water is expelled?
Archimedes tells us the lifting power of a balloon (how much mass it can lift) is equal to the difference between the mass of the balloon and the mass of the air it displaces. That is, if the balloon occupies the same volume as 10 kg of air, but the balloon only weighs 2 kg, then the balloon can lift 8 kg. Airships have sometimes been filled with hydrogen (H2), but hydrogen is very flammable, and after the Hindenburg caught fire and crashed in 1937 with serious loss of life airships have nearly always been filled with helium (He) instead. gas H₂ density 0.090 kg 3 m kg He 0.18 3 m kg 1.23 3 P air m Suppose a new airship Star of Balogna will have the shape of a cylinder 100. m long, with a radius of 15.0 m, and will weigh 9200. kg without any gas inside it.

Long-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1,08 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 165-L tank at -45.0°C, what is the final pressure in the tank?

A gas fills the right portion of a horizontal cylinder whose radius is 5.80 cm. The initial pressure of the gas is 2.64 x 105 Pa. A frictionless movable piston separates the gas from the left portion of the cylinder that is evacuated and contains an ideal spring, as the drawing shows. The piston is initially held in place by a pin. The spring is initially unstrained, and the length of the gas-filled portion is 27.1 cm. When the pin is removed and the gas is allowed to expand, the length of the gas-filled chamber doubles. The initial and final temperatures are equal. Determine the spring constant of the spring.

Your answer is partially correct. Crossing a River. You and your team come to a slow flowing river that you need to cross. The nearest bridge is 20 miles to the north, too dangerous and too far to trek with your group. You explore the area down river and discover an abandoned shed with a stash of 55-gallon drums (all empty and weighing 35.0 lb each) and a stack of 10-foot planks: you will build a raft. The six members of your team have a combined weight of 1015 pounds (assuming everyone was truthful). You also have a four-wheeler (all-terrain vehicle), which weighs 460 lb, and other gear, which adds another 325 lb. Your simple raft design is as follows: platform of planks with barrels strapped to the bottom. You estimate that the planks weigh about 49.0 lb each, and you will need 20 of them to make a platform that can accommodate everything for the one-way trip. You measure the dimensions of the cylindrical drums and find they have diameter D = 23.0 inches and height h = 34.5 inches…
Manufacturers of headache remedies routinely claim that their own brands are more potent pain relievers than the competing brands. Their way of making the comparison is to compare the number of molecules in the standard dosage. Tylenol uses 325 mg of acetaminophen (C8H9NO2) as the standard dose, while Advil uses 2.00 x 102 mg of ibuprofen (C13H1802). Find the number of molecules of pain reliever in the standard doses of (a) Tylenol and (b) Advil. (a) Number Units (b) Number Units

Consider two containers with the same volume and temperature. The first container is labelled "Dry" and holds "dry" air = a ratio of nitrogen (N2) and oxygen (O2). The second container is labelled "Humid" and holds "moist" air = the SAME ratio of nitrogen and oxygen, but also contains water (H2O) vapor. According to the ideal gas law, if the pressures are equal, the weight of the gas inside the "Dry" container will be
The equation for calculating the work performed when a piston in a cylinder expands against a constant pressure is w = −P ∙ΔV, where ΔV is the change in volume inside the cylinder. How much work is performed (in joules) when a piston pushes against a constant pressure of 1.21 atm, resulting in a volume change of 2.56 mL? (Hint: First determine the units that must be used for each term in the equation.)(101,325 Pa = 1 atm)
