The resulting net force of an object is represented below.

- 10N

Which most likely represent the forces acting on the object?

O 163 N and 73 N

O 197 N and 1 87 N

0 - 63 N and – 73 N

0 - 97 N and - 87 N

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

Part 1: a magnetic levitation or maglev train rides rails without touching them. explain how this works using your data. include the appropriate magnet drawing in your answer. part 2: two objects are near a bar magnet. one is about 1 cm away, while the other is 6 cm away. compare and contrast the magnetic force that affects each object. use your data to answer the question

The ph is the a.independent variable b.the dependent variable c.control group
