A 4 kg box is at rest on a table. The static friction coefficient , between the box and table is 0.30, and the kinetic friction coefficient fx is 0.10. Then, a 10 N horizontal force is applied to the box.
What is the best estimate of the magnitude of the box's acceleration?

Calculate the amount of heat produced when 18000 coulombs of charge is transferred in one hour through a potential difference of 50v

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
