Mass \= Density * Volume \= (19.3 gm/cm3) x (1,449 17 cm3) \= 27966 gramsMass \= Density * Volume \= (19.3 gm/cm3) x (1,449 17 cm3) \= 27638 grams

The volume of a brick of gold is 1,449 ± 17 cm3. The density of gold is 19.3 g/cm3. What is the mass of a brick of gold?

Every body persists in its state of rest or uniform motion (constant speed) in a straight line unless it iscompelled to change that state by forces impressed on it.

What is Newton's first law?

The reason why exponential functions govern population growth rate is similar to the way spring oscillatorswork. The rate at which a population grows, its rate of change with respect to time, depends on how manyindividuals are in the population to begin with: the more individuals available to procreate the more offspringcan be produced. Therefore, the equation that governs the growth of populations is a function whose rate ofchange (slope) is proportional to itself. This is exactly the definition of an exponential to begin with

Why are exponential functions important in describing population growth?

exponential functions

What is the most widely used mathematical function in science and engineering?

Rate of change is the ratio of the amount of change in one quantity versus the amount of change in anotherquantity. Since dynamics is motion, motion represents the rates of change of position with respect to time.

What is a rate of change and how is it useful in studying dynamics?
