The correct answer is the Type of batteries
Explanation:
In an experiment, it is normal the researcher modifies one variable, in this case, the number of batteries (independent variable), and this variable affects the variable tested, in this case, the brightness of the bulb (dependent variable).
However, other factors or variables should be constant to guarantee the results are reliable. In this context, one factor that the student should keep constant is the type of batteries he uses because this is not one of the main variables and therefore it is not expected he changes this on purpose or this is affected by other variables. Moreover, by making any change the experiment can be negatively affected. For example, batteries might differ in their power capacity this can affect the brightness of the bulbs.
Answer:
1: Force, F = 200N
2: coefficient of friction = 0.5

The filament used in light bulb is Tungsten(W).. It's a metal with melting point of about 3300 °C.
The disadvantages of shared decision making are:
Adopting a wrong advice from a member can lead to a big risk to the company and the business.
Further, increased number of advice also confuses the person, about which to follow and which to ignore.
There is also diffusion of responsibility and lowered efficiency.
