An elephant weighs 600 kg. The contact area between the foot and the ground is 600 square centimeters. How much pressure does the elephant exert on the ground when it stands on the ground with four feet?

P = f / S 6 * 10 / 0.24 M2 = 2500pa, when raising two feet, the elephant's pressure on the ground is 5000Pa

What is the density of the human body?

Similar to water, it should be 1000kg / m3. Of course, if you can measure it by yourself and use buoyancy method, you can just weigh your own mass. In many places, there is no accurate value. The density of human body is different from people's understanding, but it is very close to 1000kg / M3. Moreover, when people are suspended in water, they only receive gravity and buoyancy, Therefore, according to Mg = density * GV, it can be concluded that the density of human body is about equal to that of water. I think that the measured water contains impurities, so the density should be slightly higher than 1000kg / m3, because pure distilled water, that is pure H2O, is rarely used in this test, so I think the density of human body should be slightly higher than 1000kg / m3

What is the density of the human body

See my answer: http://zhidao.baidu.com/question/7061282.html The average density of human is equivalent to that of liquid water at 4 ℃, which is bigger than 1G / cm ^ 3, but smaller than that of salt water, which is about 1-1.3. Of course, there are individual differences, which will cause different densities
