Calculate the difference in blood pressure between the top of the head and the toes of a human by treating the blood as a static fluid (this is a very crude approximation because there is a pump which is making the blood flow). Assume that the person is 162 cm tall and that the density of blood is 1060 kg/m (use g=9.8m/s^2)

What should the power status of a circuit be when measuring resistance with an ohmmeter?

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

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
