Verified answer
PHYSICAL SCIENCE When a falling object reaches a speed called terminal velocity, its speed no longer increases. The object is losing gravitational potential energy but not gaining kinetic energy. Since energy must be conserved, where must the gravitational potential energy be going? Verified answer CHEMISTRY Which of these equations does not represent a redox reaction? Explain your answer. a. $\mathrm{LiOH}+\mathrm{HNO}_{3} \rightarrow \mathrm{LiNO}_{3}+\mathrm{H}_{2} \mathrm{O}$ b. $\mathrm{MgI}_{2}+\mathrm{Br}_{2} \rightarrow \mathrm{MgBr}_{2}+\mathrm{I}_{2}$ Verified answer

This theoretical equality is of little practical value when the scale is put to use as a measuring instrument.
Which of the following units are possible units for density quizlet?Two common units of density are grams per cubic centimeter (g/cm3) and grams per milliliter (g/mL). A stopwatch can be used to measure time.
Why are units always used in measurement?For most quantities a unit is necessary to communicate values of that physical quantity. For example, conveying to someone a particular length without using some sort of unit is impossible, because a length cannot be described without a reference used to make sense of the value given.
