Take measurements of resistances of various lengths of a wire of constant diameter. Make a graph of resistance against length / cross-sectional area of wire. The gradient of the straight line section will be equal to the resistivity of the wire.

How do you convert conductivity to resistivity?
Conductivity is a measure of the ability of a substance to conduct electricity. Resistivity is a measure of how strongly a substance resists the flow of an electric current. So conductivity and resistivity are opposed to each other. A good conductor like copper has a low resistivity, and a good insulator like glass has a low conductivity and a high resistivity. Mathematically, conductivity and resistivity are inverses of each other, so it is quite easy to convert conductivity to resistance.
How do you measure and graph changes in motion?
you would see if its a proportional line or if its not
What change in resistivity if length is doubled?
Resistivity is a property of a substance, and doesn't depend on the dimensions of a sample. If the length of a conductor is doubled, then its resistance doubles but its resistivity doesn't change.
What is resistivity and what factor does it depend?
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is theohm⋅metre (Ω⋅m)It defined as resistance offerde by a unit length and cross section area conductor.It depends on material used.it depends on relexation time and temperature.
If a wire of resistivity is stretched to thrice its initial length what will be its new resistivity?
the resistivity will increase by nine times

Which graph is used to measure quantity?
bar graph
What are Disadvantages of two probe method to measure resistivity?
volume of material used
How can you measure a shockwave on a point 7.2?
seismometers, gravity meters, magnetometers and electrical resistivity meters.
Which type of graph would be best to measure in minutes?
The best graph for minutes would probably be a line or bar graph to measure something over time. Your welcome!
What is position in a graph?
The position on a graph or a Cartesian plane is the measure of its edges with respect to the co-ordinates of the graph.
Is graph a latin or a greek root?
Graph is a Greek root meaning "to write."
What graphs can you use to measure correlation?
A scatter graph can be used to establish whether or not there is correlation and to get an approximate idea as to its strength. But no graph will actually measure correlation.
What does the graph measure?
graph measures different things, may be of percent of something or just calculing
What does a bar graph measure?
It measures things between different groups, for example, a sandwich is a things, but you can use a bar graph to measure different kinds of sandwiches.
How do you convert a percent into a degree measure?
convert 27%to a degree measure on a circle graph
How do you number the y axis on a graph?
measure it with a protractor
