What will be the effect on capacity of parallel plate capacitor if the whole space?
What will be the effect on capacity of parallel plate capacitor if the whole space? Completely filling the space between capacitor plates with a dielectric increases the capacitance by a factor of the dielectric constant: C = KCo, where Co is the capacitance with no dielectric between the plates. How can we increase the capacity […]

What is lithium-7 used for?
What is lithium-7 used for? Li-7 is used to control the pH level of the coolant in the primary water circuit of pressurized water reactors. Li-7 is also used for the production of the medical research radioisotope Be-7. Li-6 is used in thermonuclear weapons and the export and use of Li-6 is therefore strictly controlled. […]
What are the two main reasons air pressure changes?
What are the two main reasons air pressure changes? Although the changes are usually too slow to observe directly, air pressure is almost always changing. This change in pressure is caused by changes in air density, and air density is related to temperature. What are the two factors influencing the movement of air or wind? […]
