abundant on the earth and is a pretty dense rock (most the rock of the earth is as dense, if not denser than basalt). So…the denser the rock the better your approximation.Density is defined by the simple formula:Density = Mass / Volume Where mass is defined in grams or g Volume is...
If you plug all of these values in and solve for M1, you find that the mass of the Earth is 6,000,000,000, 000,000,000,000,000 kilograms (6 x 1024 kilograms, or 1.3 x 1025 pounds). Mass vs. Weight Why is it "more proper" to ask about the Earth's mass rather than weight...
But at this point, BMI interpretations for adults over 19 years of age do not adjust for sex or age. BMI formulas These are the formulas for calculating BMI: Metric weight (kg)/[height (m)]2 This is your weight in kilograms divided by your height in meters squared. Since metric height...
- The mass of an object determines its gravitational force. (质量决定物体的重力。) - The car's mass is 1,500 kilograms. (这辆汽车的质量是1,500千克。) - The mass of the Earth is approximately 5.97 x 10^24 kilograms. (地球的质量约为5.97 x 10^24千克。) 2. 大量的意义: - There is...
