Why are most high mass stars located in spiral arms? Star formation caused by density waves Since the criteria for cloud collapse (the Jeans instability) depends on density, a higher density makes it more likely for clouds to collapse and form stars. As the compression wave goes through, it triggers star formation on the leading […]

How do you find the force of a hydraulic system?
How do you find the force of a hydraulic system? You typically measure hydraulic pressure in pounds per square inch (psi), which is force per unit area. To calculate the force produced, multiply the pressure by the area of the hydraulic cylinder’s piston in square inches. This will give you the force in pounds, which […]

Is calcium fluoride acidic or basic?
Is calcium fluoride acidic or basic? CaF2 is slightly basic. The reason is HF is a weak acid ( but it is very corrosive). When dissolved in water, the F- ion formed will undergoes hydrolysis reaction with water molecules forming HF and OH-. Thats why, it is basic. Does calcium fluoride dissolved in water? Calcium […]
How many half-lives until a drug is out of your system?
How many half-lives until a drug is out of your system? Even further, 94 to 97% of a drug will have been eliminated after 4 to 5 half-lives. Thus, it follows that after 4 to 5 half-lives, the plasma concentrations of a given drug will be below a clinically relevant concentration and thus will be […]
