This information refers to the general prevalence and incidence of these diseases, not to how likely they are to be the actual cause of Muscle rigidity. Of the 73 causes of Muscle rigidity that we have listed, we have the following prevalence/incidence information:
the mass of the Earth. Solve for the mass of the Earth: m1 = aR 2/G = _____ kg Questions 1. Why is it a good idea to take many measurements and average the results? 2. Compare your value for the mass of the Earth to the true value of 6 x 1024 kg. That is, calculate the percentage difference: 3. How does your value for the acceleration compare to the actual value of 9.8 m/s2? With this answer in mind, how does your measurement for the acceleration of an object affect your derived value for the mass of the Earth? 4.
I also calculated numbers for the density of the Earth. I knew the mass of the Earth in grams is 5.979 Ã 1027. Also, the radius in centimeters is 6.3713 Ã 108. I plugged this information into the 4/3Ïr3 formula in order to find the volume. I got the answer 1.084227366 Ã 1027 cm3. I then divided the volume into the mass and got 5.519 g/cm3 as the density of the Earth.
