Why did we use two masses with identical geometries for the simple pendulum experiment?
Using two masses with identical geometries in a simple pendulum experiment allows for controlling variables and ensuring reproducibility of results. By keeping the mass and shape of the objects consistent, we can isolate the effect of the independent variable being tested (e.g., length of the pendulum) on the dependent variable (e.g., time period of oscillation).
What is it called when a variable makes another variable change but no other variable changes?
It is called a direct or simple relationship between the two variables. This means that as one variable changes, the other variable changes in a predictable way and no other variables are involved in influencing the relationship.
Why does time period of simple pendulum is independent from mass?
The time period of a simple pendulum is independent of mass because the formula for the time period only depends on the length of the pendulum and the acceleration due to gravity. The mass of the pendulum bob does not affect the time it takes for one complete swing because the force due to gravity acts equally on all masses. This makes the mass cancel out in the equation, resulting in a time period that is mass-independent.
What are the physical parameters in the investigation of a simple pendulum?
The physical parameters of a simple pendulum include (1) the length of the pendulum, (2) the mass of the pendulum bob, (3) the angular displacement through which the pendulum swings, and (4) the period of the pendulum (the time it takes for the pendulum to swing through one complete oscillation).
What type of simple machine is used to make a vise open and close?
A screw is the simple machine used to make a vise open and close. The screw allows for the controlled movement of the two jaws in the vise, enabling it to grip and release objects effectively.
Simple regression and multiple regression?
Simple regression is used when there is one independent variable. With more independent variables, multiple regression is required.
How many variables can be tested in an experiment?

When was A Simple Investigation created?
A Simple Investigation was created on 1997-03-31.
What are the advantages of regression over correlation?
Correlation is a measure of association between two variables and the variables are not designated as dependent or independent. Simple regression is used to examine the relationship between one dependent and one independent variable. It goes beyond correlation by adding prediction capabilities.
What is the define for simple investigation?
a simple investigation is one where the police think there is nothing amiss so they just do a simple one.
Types of hypothesis?
The two main types of hypotheses are simple and complex hypothesis. The simple hypothesis predicts the relationship between a single dependent and independent variables. On the other hand, the complex hypothesis describes the relation between two or more dependent and independent variables.
Simple non-array variables are usually passed to methods by?
Simple non-array variables are usually passed to methods by value.
What is the difference between simple and multiple linear regression?
I want to develop a regression model for predicting YardsAllowed as a function of Takeaways, and I need to explain the statistical signifance of the model.
How do you calculation joint probability?
You have a function with two arguments (inputs). After that, the calculations depend on whether or not the two random variables are independent. If they are then the joint distribution is simple the product of the individual distribution. But if not, you have some serious mathematics ahead of you!
What are the merits and demerits of multiple line graphs?
The main advantage is that it allows you to see how different dependent variables change according to changes in the same "independent" variable. It is relatively simple to use two vertical axes for the dependent variables, but the degree to which the two axes relate to one another is arbitrary. Furthermore, if the ranges of the dependent variables are very different the chart becomes unreadable.
Is Simple curiosity is not a legitimate reason to complete a scientific investigation?
Sure it is.
What is the independent variable in a pulley?
The independent variable is the simple machine used and the thing your sliding it on.
