⩥ Lab 1: Measurement
How do you find the volume of an object? Answer: (4/3)*pi*R^3
**there is a sphere volume program
⩥ Lab 1: Measurement
What was the purpose of this experiment? Answer: The purpose of this
experiment is to become familiar with methods of measurement and
error.
,⩥ Lab 1: Measurement
What is the standard unit for length, mass, and time in the MKS metric
system? Answer: Meter, Kilogram, Second
⩥ Lab 1: Measurement
Why are units important when reporting the result of a measurement?
Answer: Units are important because they allow for a comparison to a
standard which helps to understand the results.
⩥ Lab 1: Measurement
An object is estimated to be 2.5 cm long. When measured with a Vernier
caliper its true length is determined to be 2.47 cm. What is the percent
error of the estimated value? Answer: 1.21 %
⩥ Lab 1: Measurement
Complete the following calculations using the explanation of significant
figures given below. When multiplying and dividing several quantities,
the number of significant figures in the final answer is the same as the
number of significant figures in the quantity with the least amount of
, significant figures that is being multiplied. When adding and subtracting
several quantities, the number of decimal places in the result should
equal the smallest number of decimal places of any term in the sum.
Given: x= 12.24 y= 5400 z=11.572
Determine:
x*y*z=
x+z= Answer: x*y*z= 7.6 x 10^5
x+z= 23.81
⩥ Lab 1: Measurement
Consider the results of your reflex time measurement. What precision, in
fractions of seconds, can you claim for the stopwatch? Answer: A
stopwatch has precision to the hundreds place whereas the reflex testing
is precise to the tenths place so there is a limit to its precision.
⩥ Convert the following measurement:
4.54 cm to mm Answer: 45.4 mm
