Please help!! I’ll give Brainilsy What question can Jude answer with this investigation?

A. How many trials are needed to investigate how fast materials slide?

B. How is friction different with different materials?

C. Is a table the best way to record data from an investigation?

D. What force is need to push a block down a ramp?

The correct answer is B. How is friction different with different materials?

Explanation

In the graph you can see the time it took each of the materials to descend the ramp, Judas did two tests for each material. In the case of the uncoated wooden block, the decrease was in 4.2 seconds (first test) and 3.9 seconds (second test. In the case of the block wrapped in wax paper, the results were 6.1 seconds (first test) and 6.5 (second test). In the case of the wooden block wrapped in sandpaper, the results were 3.0 seconds (first test) and 3.3 seconds (second test). With the result of his investigation, Judas can ask himself issues related to the particularities of each material, for example, its friction when descending. Therefore, the correct answer is B How is friction different with different materials?

yes i can of course like what is it gonna be about

the two things that develop a strong social foundation are: a. separation of church and states e. education received attention separation of church and states separate the illogical  argument that came from religious beliefs to a fact based belief. while education will make us remember the past to avoid the repeat of our mistakes.
