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.
The Hill sphere, or gravitational sphere of influence, of Earth is about 1.5 Gm or 1,500,000 km in radius. This is the maximum distance at which the Earth's gravitational influence is stronger than the more distant Sun and planets.he mass of the oceans is approximately 1.35 Ã 10 metric tons, or about 1/4400 of Earth's total mass. The oceans cover an area of 7014361800000000000â 3.618Ã108 km2 with a mean depth of 7003368200000000000â 3682 m, resulting in an estimated volume of 7018133200000000000â 1.332Ã109 km3.
