An is a line in which waves move that are moving together all in the same phase O Light wave O Wave front O Incident beam O Dark wave

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

Often called simply "velocity," this is the velocity of an object at a particular moment in time.

Which compound is held together by the electrostatic force between two ions? a. co2 b. cci4 c. h2s d. mgf2
