In summary, graph plotting is used to visually represent the relationship between two variables, 1/u and 1/v, in order to determine the values of u and v by finding the intersection point of the two lines. It is important to use 1/u and 1/v instead of the original values to make it easier to plot on a linear scale and avoid potential errors. The slopes of the lines on the graph represent the inverse values of u and v. At least two data points are needed to plot a graph, but having more can improve accuracy. Graph plotting can be used to determine u and v in linear equations, but may not be efficient for more complex equations.

Plot a graph of 1/u against 1/v and find the intercept on the 1/u axis.

Determine from your graph

a) the value of u, when v= 27cm
b) the value of v,when u 27cm

I'm sorry but I don't really understand how to find 27cm on my graph when there's nothing like that on it.

Nevermind I'm stupid =.= just do 1/27

Related to Graph Plotting: Determine u & v When Given 1/u & 1/v

1. What is the purpose of graph plotting in determining u and v when given 1/u and 1/v?

The purpose of graph plotting is to visually represent the relationship between two variables, in this case u and v. By plotting the values of 1/u and 1/v on a graph, we can determine the values of u and v by finding the intersection point of the two lines.

2. Why is it important to use 1/u and 1/v instead of u and v directly?

Using 1/u and 1/v allows us to plot the values on a linear scale, making it easier to determine the relationship between the two variables. It also helps to avoid any potential errors or confusion that may arise from using the original values of u and v.

3. What do the slopes of the lines on the graph represent?

The slopes of the lines represent the inverse values of u and v. This means that the steeper the slope, the smaller the values of u and v, and vice versa.

4. How many data points are needed to plot a graph for determining u and v?

At least two data points are needed to plot a graph. However, having more data points can help to improve the accuracy of the results and provide a better understanding of the relationship between u and v.

5. Can graph plotting be used to determine u and v in any type of equation?

Yes, graph plotting can be used in various types of equations, as long as the relationship between u and v is linear. However, it may not be the most efficient method for more complex equations with multiple variables.
