WebMay 19, 2024 · The Triassic mass extinction event occurred 200 million years ago, eliminating about 80% of Earth's species, including many types of dinosaurs. This was probably caused by colossal geological activity that increased carbon dioxide levels and global temperatures, as well as ocean acidification. An Earth mass (denoted as or , where ⊕ is the standard astronomical symbol for Earth), is a unit of mass equal to the mass of the planet Earth. The current best estimate for the mass of Earth is M⊕ = 5.9722×10 kg, with a relative uncertainty of 10 . It is equivalent to an average density of 5515 kg/m . Using the nearest metric prefix, the Earth mass is approximately six ronnagrams, or 6.0 Rg.

Web1 day ago · Internet has seen a deluge of Artificial Intelligence (AI) chatbots in the last few months with the most popular of the lot being OpenAI's ChatGPT. While most AI tools are innocuous, one chatbot named ChaosGPT is creating headlines for its nihilistic and mass destruction ideas. WebScience Physics Two point charges of mass m each are suspended in the gravitational field of the Earth by two non-conducting massless strings, each of length 1, attached to the same fixed point. The spheres are given equal charges Q of the same sign. As a result each string makes angle a to the vertical (see figure below). Calculate m, if 1 = 78.3 cm, Q = 4 µC … dave campbell\u0027s texas football covers
