Are LED continuous or discrete? LED lights, or “Light Emitting Diodes,” as they are better known, emit a continuous spectrum. The spectrum they cover is not as broad as other colored lights or incandescent lights. How do you know if a variable is discrete? A discrete variable is a variable whose value is obtained by […]

Is G positive or negative? g always acts downwards and is a positive number 9.8 m/s². It can be negative or positive depending upon the sign you assign to upward and downward directions. g is a number, like 5.6 or pi. There is no “positive or negative” version of g. How was Big G calculated? […]

Can tires lose pressure without caps? It’s not uncommon for valve stem caps to fall off. While a missing valve stem cap may seem harmless, it can lead to loss of air pressure. Without a cap, dirt and debris will enter the valve stem where it can break through the seal. When this occurs, air […]
