1 Find the acceleration of an object if there is a force of 20 newtons in one direction and 10 newtons in the opposite direction. The mass if 2 kg.

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

Which of the following is the result of the nuclear weak force? the instability of large nuclei the repelling force between positively charged protons the structure of the atom certain types of nuclear decay

An object's buoyant force and weight mean the same thing.a. trueb. false
