To make a permanent magnet, all you have to do is encourage the magnetic domains in a piece of metal to point in the same direction. That's what happens when you rub a needle with a magnet — the exposure to the magnetic field encourages the domains to align. Other ways to align magn...
"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 exercise, when to eat our meals, when and what information we need...
(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...
These atomic numbers correspond to the number of protons and electrons, as well as the approximate average number of neutrons, in each element. You can get an estimate of neutron number for an element by subtracting its atomic number from its atomic mass, listed at the center bottom of ...
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...
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?
he used an example where we were given abundance and amu for all the isotopes and just had to use the average atomic mass formula And this is exactly what you need to do here. You are just not given one piece of information, so you have to determine it for yourself. Logged What men...
One common strategy of such industries is to weaponize print (sometimes known as "legacy") media and social media, creating and spreading disin formation about green technologies—for instance, spreading the myth that heat pumps do not work in cold weather. The story becomes even more ...
