Answer:
12.7m
Explanation:
FORMULA
for an approximate result, divide the length value by 39.370078
Answer:
Other side
Opposite function
On both sides of the equation
In the numerator and not the denominator
Explanation:
To isolate a single variable when rearranging equations, move all other variables to the other side of the equation by using the opposite function on them and remembering to perform that operation on both sides of the equation. Make sure the rearrangement has the target variable in the numerator, not the denominator.
Answer:
A) Precision
B) Accuracy
C) Precision
D) Accuracy
Explanation:
<em>Accuracy</em> and <em>Precision </em>are factors that determine whether a given analysis is appropiate or not.
Accuracy refers to how close the experimental result is to a <em>known, theoretical or accepted value. </em>For this reason every method that checks the accuracy uses a standard -this could mean repeating the test using the standard instead of the sample, or adding a known amount of analyte to the sample-, in order to compare the results.
Precision refers to how close repeated the results of different tests are to each other, in other words, it refers to the <em>repeatability </em>of the method. A test for precision would require that the method is done several times, in order to check how close the results are to each other, regardless of whether those results are close to the expected value.
Answer:
50 mL
Explanation:
We can solve this problem by using Boyle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:
where
p is the pressure of the gas
V is the volume of the gas
The equation can be rewritten as
where in this problem:
is the initial pressure of the gas in the coke
is the initial volume
is the final pressure
Solving for V2, we find the final volume:
