Which equation can correctly express the relation between force, acceleration, and mass? a) F = m × a
b) F = m ÷ a
c) F = m − a
d) F = m + a

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

Argon, neon, and xenon are examples of

Which best describes the difference between internal and thermal energy?
