Is C 13 stable or unstable?
Is C 13 stable or unstable? Both 12C and 13C are called stable isotopes since they do not decay into other forms or elements over time. What is the difference between C 12 and C 14? The difference between carbon-12 and carbon-14 is the number of neutrons in each of their atoms. Atoms of carbon-12 […]
Are electrons attracted to magnetic fields?
Are electrons attracted to magnetic fields? But if you put a north pole and a south pole together, the magnets will stick together because the north and south poles attract each other. Just like protons and electrons—opposites attract in magnets. Which force field can both accelerate an electron and change its speed? Which force field […]

Can you see the North Star in Australia?
Can you see the North Star in Australia? During a 25,800-year cycle, the position of Earth’s axis in space traces out a 46.88°-wide circle on the sky. At that time, Polaris will be visible anywhere north of 45.95° south latitude (90°–44.62°+0.57°), and our current “North Star” will grace the skies above all of Africa and […]
Why is the North Star Fixed?
Why is the North Star Fixed? Polaris, the North Star, appears stationary in the sky because it is positioned close to the line of Earth’s axis projected into space. As such, it is the only bright star whose position relative to a rotating Earth does not change. All other stars appear to move opposite to […]
Does current flow through capacitors?
Does current flow through capacitors? Current does not flow through a capacitor but voltage is stored in a capacitor and consequently store electrical energy across it’s plates wherein these plates are separated in between (sandwhiched) by a dielectric material or insulator. How does current flow through capacitors? Current flows through capacitor plates which induces the […]
What is the formula of extension?
What is the formula of extension? e is extension = (l-lo); l is the stretched length and lo is original length, and. k is the gradient of the graph above. It is known as the spring constant. How do I calculate my extension length? Analysis For each result, calculate the extension: extension = length – […]
