A variable must be in place of a number, or representing a range of possible values. Otherwise, it is a constant and so yous imply replace it with the value of that constant.
The independent variable is the thing you are changing/varying. The dependent variable is the thing you are measuring. This variable should be affected by the independent variable. Control variables are anything that must be kept constant. If there are any other factors which affect the dependent variable, then these need to be controlled so that they do not have any significant effect (basically ensuring that you are actually measuring the effects of the independent variable).
The differentiation of a constant is zero because a constant value does not change with respect to the variable being differentiated. The derivative measures the rate of change of a function, and since a constant has no change, its derivative is zero.
Controlled variables are things that must be controlled and kept the same during the experiments in order to prevent them from having an impact on results.
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. A coefficient must be a number or a symbol for a constant number. This includes pi and e as coefficients.2x=6(pi)x=44(x+2)=19
In an experiment, variables that must be kept constant are called control variables. Two common examples include temperature and pH levels. These variables should be kept constant to ensure that any changes observed in the dependent variable are a result of the independent variable being tested.
Variables that must be kept constant in an experiment are known as control variables. These variables are factors that can influence the outcome of the experiment, so keeping them constant ensures that any observed changes are due to the independent variable being tested.
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
Temperature and the amount of gas (moles) must be kept constant for Boyle's law to hold true. This means the pressure and volume of a gas are inversely proportional provided the temperature and amount of gas remain constant.

When non-experimental variables are held constant, it means keeping factors other than the independent variable the same for all participants or conditions in order to ensure that any observed effects are due to the independent variable and not to any other variable. This helps to isolate the impact of the independent variable on the dependent variable and strengthens the validity of the experiment.
The condition for maximum efficiency of a d.c. machine is that VARIABLE LOSSES must be equal to CONSTANT LOSSES i.e., variable losses = constant losses..
There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.
No, if an object has constant speed, its velocity must also be constant. Velocity is a vector quantity that includes both speed and direction. If the speed is constant, the direction must also be constant for the velocity to be constant.
"Constant pressure" means the pressure must not change.
Factors that must remain constant in an experiment are called control variables. These factors are kept consistent to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Control variables include things like temperature, time, type of equipment used, and environmental conditions.
