Why must scientist control variables in their experiments?
An experiment is a simulation of complete or part of a real scenario in a controlled environment. We come to know of various outcomes of an experiment based on the values/degree of the variables in different quantity/quality. Unless the variables are controlled, experiment can go out of hand and sometimes become a real disaster.
Velocity provides information about what?
Velocity is a vector quantity, which means it is made up of more than one numeric value. Velocity vectors must contain information on speed and direction.
What does the responding variable mean in a science experiment?
The responding variable is the one variable that changes as a result of altering the manipulating variables. In an experiment, different conditions of the responding variable can be observed, such as quantity, quality, time, distance and height.

A quantity formed from the combination of other measurements is a what quantity?
derived quantity
Is velocity a scalar quantity or vector quantity?
Velocity is a vector.Its magnitude is called 'speed'.
What is information from an experiment that can be assigned a number or a quantity and can often be used to construct a graph.?
??????
What is information from and experiment that can be assigned a number or a quantity and can often be used to construct a graph?

What isth information from an experiment that can be assigned a number or a quantity and can often be used to construct a graph?
The information from an experiment that can be assigned a number or a quantity is referred to as quantitative data. This type of data allows for measurable comparisons and statistical analysis, making it suitable for graphical representation. Examples include measurements like height, weight, temperature, or time, which can be plotted on graphs to visualize relationships or trends in the data.
What is done to a variable represent an unknown quanity?
A variable is assigned to represent an unknown quantity.
Who conducted an experiment to determine the quantity of charge carried by an electron?
Robert Milliken
How is algebra related to chemistry?
Ø In chemistry, algebra can be used to calculate the quantity of a substance required in an experiment. Also, it is used to calculate the quantity of various substances formed in an experiment. Problems of Mole concept are soved on this basis only.
What is the difference between average and weighted average?
weighted average is an average in which each quantity to be averaged is assigned a weight. These weightings determine the relative importance of each quantity on the average.
What is being measured in an experiment?
accurate values of the quantity that you wanna measure using certain properties of it.
What do you call a symbol that can represent a quantity?
VARIABLE. When this variable has a fixed number assigned to it and does not change, it is called a "fixed variable".
When a chemist perform an experiment the quantity is being tested is the?
The quantity being tested in a chemistry experiment is typically referred to as the independent variable. This is the variable that the chemist deliberately changes or manipulates to observe how it affects other variables in the experiment. The dependent variable, on the other hand, is the variable that is being measured or observed and is influenced by the changes in the independent variable.
When a chemist performs an experiment the quantity that being tested is the?
a. control d. law c. theory d. variable
What is a quantity that is ignorant of direction referred to as?
A scalar quantity is a quantity that is ignorant of direction. Scalars have only magnitude, such as temperature or distance, and do not have associated direction information.
