Something that changes during an experiment. A variable is something that is bound to change and not constant
In a mathematical statement a variable is something which can take on different values; it is usually represented by a letter, though a word could be used. Examples include: x + 5 (x is a variable) area_rectangle = lw = length × width (l, w, length and width are all variables), area_circle = πr² = π × radius² (r and radius are both variables)
Variable means that something is liable to change, is not constant. For instance, weather is very variable in Britain. Our weather can change hourly, with rain, sun, etc.
15 micrometers = 1.5 × 10^-5 meters
Explain about the guidelines used for designing procedures?
1 km = 0.621371 miles
yes, it is an example of a primary source.
during an experiment
20 US gallons of gasoline equals about 75.708 liters.
By unit of length and distance and conversion ,we can say that
1 cm =0.3930 in
26 cm=10.23 inches
1 meter = 100 centimeters
A record that is made during or right after an event
0.8 = 8/10 = 4/5, so 311.8 = 311 and 4/5.
THey contain more details about the experiment
3,450 is written as 3.45 × 103
