A large hotel has asked you build a water fountain that is fed by a 15 cm diameter cylindrical pipe that carries water horizontally 8m below the ground. The pipe turns upwards and eventually fires water out of the 5 cm diameter end of the cylindrical pipe, which is located 1.75 m above the ground, with a speed of 32 m/s. Water has a density of 1,000 kg/m3. What gauge pressure is required in the large underwater horizontal pipe for...

A cylindrical tank with a large diameter is filled with water to a depth D = 0.405 m. A hole of cross-sectional area A = 5.62 cm^2 in the bottom of the tank allows water to drain out. (a) What is the rate at which water flows out, in cubic meters per second? (b) At what distance below the bottom of the tank is the cross-sectional area of the stream equal to one-half the area of the hole?

Water flows at the rate of 3.48 kg/s through a hose with a diameter of 3.00 cm. (a) What is the speed of water in this hose? (b) If the hose is attached to a nozzle with a diameter of 0.750 cm, what is the speed of water in the nozzle? (c) Is the number of kilograms per second flowing through the nozzle greater than, less than, or equal to 3.48 kg/s? Help! My answers are wrong, heres what I...

Consider a bacterium (radius ~1 μm) swimming through water at a speed of 25 μm/s. (a) How much force do the flagella of the bacteria have to generate to maintain that speed? (b) The motor protein kinesin generates a force of 6 pN. Given that the viscosity of the cytoplasm is ~1000 times that of water (for large objects like organelles), how fast could a single kinesin molecule move a bacterium though the cytoplasm environment? Express your answer in μm/s.

A bicycle racer is going downhill at 15.0 m/s when, to his horror, one of his 2.42-kg wheels comes off when he is 73.0 m above the foot of the hill. We can model the wheel as a thin-walled cylinder 85.0 cm in diameter and neglect the small mass of the spokes. How fast is the wheel moving when it reaches the foot of the hill if it rolled without slipping all the way down? Express your answer in meters...

A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. It takes a time of 2.30 s for the boat to travel from its highest point to its lowest, a total distance of 0.620 m . The fisherman sees that the wave crests are spaced a horizontal distance of 5.90 m apart. How fast are the waves traveling? Express the speed v in meters per...

When you urinate, you increase pressure in your bladder to produce the flow. For an elephant, gravity does the work. An elephant urinates at a remarkable rate of 0.0060 m3 (a bit over a gallon and a half) per second. Assume that the urine exits 1.0 m below the bladder and passes through the urethra, which we can model as a tube of diameter 8.0 cm and length 1.2 m. Assume that urine has the same density as water, and...

This question will deal with tsunamis, long-wavelength waves caused by seismic activity, bolide impacts, landslides, and in rare cases, atmospheric disturbances. Tsunamis can propagate across ocean basins and can be incredibly destructive. Tsunamis are interesting from a perspective of wave phenomena because when they are in deep water they are almost undetectable. Their wave height is on order of at most a few meters. However, they have very long wavelengths, typically 200 km. This makes their phase speed very fast....

1 In the absence of oxygen, cells consume glucose at a high, steady rate. When oxygen is added, glucose consumption drops precipitously and is then maintained at the lower rate. Why is glucose consumed at a high rate in the absence of oxygen and at a low rate in its presence? 2 In the following diagram showing the distribution of thermal energy in a population of substrate molecules, the energy thresholds indicated by numbers represent ... Energy per molecule Number...

Background Almost all animal and plant cells require oxygen and give off carbon dioxide. This is called gas exchange and it occurs by passive diffusion. Some animals do all or most of their gas exchange across their skin (for example amphibians) but they have very low metabolisms and use very little oxygen and get rid of very little carbon dioxide. On the other hand humans (and other mammals) have very high metabolic requirements and we can’t rely on gas exchange...
