What is the pressure at the bottom of a swimming pool that is 3 meters in depth? 29,400 pa What is the pressure at the bottom of a pool? The chart shows that 2.31 feet of water will create one PSI. So in CPO class, I ask the students: “How much pressure is at the […]

Is it safe to swim to a sandbar? The trough can be a gentle swim, but the sandbars around it can also shift to create the rip currents — channeled rushes of water pulling away from shore — that have caused so many drownings and near drownings over the years. “You are always going to […]

What happens when a cell with 1% salt gets put into a 10% salt solution? It is a type of passive transport. A cell has a 1% salt concentration. It is placed into a solution containing a 10% salt concentration. Water will move out of the cell, causing it to shrink. What are examples of […]

What is the relationship between the earth and the moon? The Moon is smaller than the Earth and orbits around the Earth in 27.3 days as the Earth revolves around the Sun. The Moon is held in orbit around the Earth by the force of gravity. In turn the Earth and all the other planets […]

How do you do a well yield test? Determine the volume in gallons per foot of well bore based on the well diameter (Table 1). Multiply the gallons per foot of well bore times the footage of water level rebound during the recovery. Then divide the result by the time of this recovery to a […]

Which is best analog or digital? Digital recordings can have a greater signal-to-noise ratio depending on the bit depth of the recording. This jump in elevation can create a digital noise. The smooth analog signal matches the recorded sound wave better than the steps of a digital recording. What are the three components of a […]

Is a woodchuck and a beaver the same thing? The woodchuck and the beaver belong to the same rodent species, and are closely related to the squirrel family. Though they exhibit certain resemblance like the ever-growing teeth, gnawing habits, and ability to regulate temperature, there are a lot of differences in their habitats, breeding and […]

How do I increase the resolution of my GC? To improve the resolution of earlier eluting peaks, decrease the initial temperature or increase the initial hold time. Decreasing the initial temperature usually results in the largest resolution improvement, but analysis times are substantially increased (Figure 32a). What affects resolution in GC? Changes in resolution are […]

What is H in Maxwell equations? The four Maxwell equations, corresponding to the four statements above, are: (1) div D = ρ, (2) div B = 0, (3) curl E = -dB/dt, and (4) curl H = dD/dt + J. Read More on This Topic. light: Maxwell’s equations. In the early 1860s, Maxwell completed a […]

Did Israel kill the Munich terrorists? The Munich massacre was an attack during the 1972 Summer Olympics in Munich, West Germany, by eight members of the Palestinian terrorist group Black September, who took nine members of the Israeli Olympic team hostage, after killing two of them….
