Over the Counter Medications Drugs that are safe and effective for use by the general public without a prescription are defined as over-the-counter (OTC) drugs. These drugs are often located on shelves in pharmacies with easy access by patients, but may also be located in non-pharmacy outlets, such as grocery stores, convenience marts and large discount retailers.
Objects simply do not acquire charges on the order of 1.00 Coulomb. In fact, more likely Q values are on the order of 10-9 or possibly 10-6 Coulombs. For this reason, a Greek prefix is often used in front of the Coulomb as a unit of charge. Charge is often expressed in units of microCoulomb (ÂµC) and nanoCoulomb (nC).
Density is defined as mass per unit of volume. The commonly used formula to determine the density of an object is Ï = m/V, Ï (rho) represents density, m represents mass, and V represents volume. The units used to indicate density are [kg/m 3 ] or more commonly used [g/cm 3 ].
