Volume flows in the individual pipes?
Hello? I have a question: How do you calculate the flow rates for parallel pipes? I'm really stuck and would appreciate any suggestions.
Hello! Can someone explain to me what focal length is? I don't understand it, nor do I understand image size, object distance, and image distance. Thanks in advance.
Hello, Could someone perhaps explain to me when to use which formula? My guess is that the top two are used for the small angle approximation, and the others when the small angle approximation doesn't apply. I also wanted to ask whether the formulas below could be used for both maxima and minima. Thanks !
I'm currently working through some exercises and, in one case, I took the time to carefully follow how the oxygen atoms redistribute their electrons. However, I'm a little unsure about the last step and am looking for help: https://ibb.co/qxmBQDp
Good evening dear GF community. I'm a type 1 diabetic and have a blood glucose monitor that uses CR2032 batteries. I just put two new batteries in a small plastic case so I'm always well-equipped for travel in case the meter's batteries run out. My concern is that these batteries might leak on their own,…
Hey! Gravity is a fundamental force—every object and particle with a positive mass attracts each other. This includes you and a molecule on the other side of the universe. While the gravitational force weakens with distance, two questions arise: 1.) How can the universe expand against gravity? Is there such a thing as "antigravity"? After…
Forces are interactions, meaning that when a force is applied, an opposing force of equal strength always occurs. The forces should then balance each other out, right? That means you can't exert a force on a body in that sense?
this goes analogy to electrics so I don’t have to type too much, here is a source that will certainly help you further
