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.
Scientists calculate that the total mass of the oceans on Earth is 1.35 x 1018 metric tonnes, which is 1/4400 the total mass of the Earth. In other words, while the oceans cover 71% of the Earth's surface, they only account for 0.02% of our planet's total mass. The origin of water on the Earth's surface, as well as the fact that it has more water than any other rocky planet in the Solar System, are two of long-standing mysteries concerning our planet.
