Why cant dimensional analysis be used to determine if a given equation is correct?
Dimensional analysis simply ensures that two sides of an equation have the same dimensions. By "dimensions" I mean quantities like distance, pressure, force, time, electric charge, etc. For example, a distance can not equal a time. So, if the dimensions are wrong, the equation is wrong, but if the dimensions are right, the equation may be right or it may be wrong. Getting the dimensions right is only part of the task!
Explain how you an determine if the number is a solution of an equation?
Substitute the number in the equation. If the resulting statement is true the number is a solution to the equation.
How do you determine if a given expression is an equation?
An equation has an equals sign ( = ). Equations assert the absolute equality of two expressions.
What are two ways to determine if an equation is linear?
All the variables that appear in it have the exponent 1. If you plot the equation, it is a straight line.
What formula do you need to solve for distance if given foce and work?
The formula for finding work is: Work = force X distance. To find distance, you must divide both sides by force. After simplifying the equation, the new equation will read: distance = work divided by force
How is opacity measured?
The equation for opacity is quite complex. It is determine by I(x) = Ioe -Kvpx. X is the distance that the light has traveled.
What does a reactant do in an equation?
The reactants in the equation determine what product you get.
Determine the nature of the solution of the equation?
The answer will depend on the equation.
What is the equation for converting water from a distance to mass and volume?
There is no such equation, what do you mean by "water from a distance".
What is the equation you use to determine for momentum?
The equation is force multiplied by accelaratin
How would you determine the difference between a solution and an equation?
An equation can lead to a solution.
What are the three ways to write speed equation to find the time distance and speed?
The basic definition of speed is: speed = distance / time Solve this equation for distance, or solve it for time, to get two additional versions of the equation.
What the equation for speed?
Distance ÷ Time (distance divided by time)
What information can you determine from the coefficients in this balanced chemical equation?
What information can you determine from the coefficients in this balanced chemical equation? Mg + 2HCl → MgCl2 + H2
What is the equation to determine who wins the presidency?
electors
How do you determine Ea by Arrhenius equation?
yes
