= distance of the object = ?
= focal length of the convex mirror = - 20 cm

Without the ability to measure, it would be difficult for scientists to conduct experiments or form theories. Not only is measurement important in science and the chemical industry, it is also essential in farming, engineering, construction, manufacturing, commerce, and numerous other occupations and activities.
Answer:
6 significant figure
Explanation:
The digits 111328 all are 6 figures with no figure being zero, neither zero after the other digits. In this case, all the numbers are significant and since they are only six numbers, then this is a six significant figure. In case we add another zero after digit 8, the zero is not significant but if added either infront of 8 or 2, the zero becomes significant.
Independent variable: the variable in an experiment which value is not changed based on any other variable. often denoted by "x"
dependent variable: the variable in an experiment which changes based on the value of the independent variable, ie how much of it you use, how often you use it, etc. often denoted by "y"
theory: an explanation as to why certain phenomena occur. supported and testable, but could change with new research / experiments, etc.
hypothesis: a guess or an estimate of what will happen during an experiment. testable, and may be wrong.
