"Well we have a scheduling program on board that has in it all of the details that we need to know in order to do the day's work. It tells us when we should go to sleep, when we should get up, when we should ex
(a) The atomic number is the same as the mass number (b) The atomic number is the same as the number of protons (c) The identity of a chemical element is determined by the number of valence electrons (d) The radi How do you determine the atomic orbitals of an atom or molecule? Wh...
To do this, it would loop around the cosmic strings. Quantum strings are highly speculative, however. Gott himself said that in order to travel back in time even one year, it would take a loop of string that contained half the mass-energy of an entire galaxy. In other words, you'd ...
Once you know the principles behind holograms, understanding how they can do all this is easy. This article will explain how a hologram, light and your brain work together make clear, 3-D images. All of a hologram's properties come directly from the process used to create it, so we'll...
While the political landscape of nuclear warfare has changed considerably over the years, the science of the weapon itself — the atomic processes that unleash all of that fury — have been known since the time ofEinstein. This article will review how nuclear bombs work, including how they're...
What is atomic energy?It's not immediately obvious but tall buildings store energy—potential energy. You have to work hard to lift bricks and other building materials up off the ground into the right position and, as long as they remain where you put them, they can store that energy ...
“For fusion, you have to do three things—you have to get enough particles together, you have to get them hot enough, and you need to hold them long enough for the reaction to take place,” says Phil Ferguson, Ph.D., director of the Material Plasma Exposure eXperiment (MPEX) Project...
How can you determine the total magnification of an object that you are observing with the microscope? What is the unit for atomic mass? A. kg B. amu How do I calculate the % error based on the mass of solution you measure vs the theoretical one?
“You’re meant to have to deal with the fact that you’ve got limited time, and probably time that’s too limited for you to do your best on every single problem, whereas the subject tests are really more about doing your best." While the subject tests were historically shorter than ...
You can safely bend, loop and wrap it to create any design you want, much as you can do with rope lights. While rope lights may cost less than EL wire, rope lights generate heat. Also, many common brands of rope light do not allow users to cut the string of lights to their ...
