It's found in Chile, Iran, Arizona, and Greece. B) Dark matter consists 90% of neutrinos and 10% of WIMPs. Time crystals were created in a lab in 2017 and in 2021, Google announced that it had made a time crystal in a quantum computer, and that the crystal had lasted for 100 seconds before the ephemeral state disintegrated. C) It is the energy of black holes. Medium Solution Verified by Toppr Correct option is C) The particles of matter are continuously moving.

B) massive objects cause more distant objects to appear much larger than they should and we can observe the distant objects with better resolution. a buffer The products of exergonic reactions contain more potential energy than the reactants that form them The matter in the air is what supports the enormous weight of a plane. It is a form of dipole-dipole interaction. Which of the following is true of protein structure? Energy is defined as the capacity to do work, or to put matter into motion. Plasma is not a common state of matter here on Earth, but it may be the most common state of matter in the universe, according to the Jefferson Laboratory (opens in new tab). The reactivity of an atom is based on the number of electrons in its outer valance shell. Atoms come together to form molecules, which are the building blocks for all types of matter, according to Washington State University (opens in new tab). 3.
