That shows that the remnant is a neutron star, which is a dead star's collapsed core and made of the densest material in the Universe. 但美国国家航空航天局詹姆斯·韦布空间望远镜的新观测数据给出了这个问题的答案。新数据表明恒星爆炸的残余物是一颗中子星,它是一颗死亡恒星坍塌的核心,由宇宙中密度...
1. How long was the supernova visible for from Earth? 2. Why could telescopes not confirm what was at the supernova's heart initially? 3. True or False?A neutron star is made of the densest material in the Universe. 4. What are two reasons why the discovery is important? 答案 1. ...
If space is curved, what fabric/material is space? What is the densest substance in the universe? What are non-ohmic conductors? What type of material would you choose for a threshold Cerenkov counter which is to be sensitive to 900 MeV/c pions but not to 900 MeV/c protons?
What is the densest substance in the universe? Which has more retentivity soft iron or steel? Which material does not follow Ohm's law? Why? a. Mercury b. Tungsten c. Platinum d. Carbon What element has the second highest electronegativity?
Neutron stars are created when massive stars reach the ends of their lives and are composed of the densest matter in the known universe.
The density is determined by both the masses of atoms and the space between atoms.In other words. The higher the mass, the higher the density. The less space between atoms, the higher the density. The densest substance on earth is the osmium. The density is 22.6 g/cm3...
The light emitted by a pulsar carries information about these objects and what is happening inside them. That means pulsars give scientists information about the physics of neutron stars, which are the densest material in the universe (with the exception of whatever happens to matter inside a blac...
What is the densest alloy? It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores.Osmiumis the densest naturally occurring element, with an experimentally measured (using x-ray crystallography) density of ...
Softballs are comprised of two parts, including a core and a covering. The material used for covering is composed of synthetic, composite or natural leather, which is commonly dyed yellow to help with visibility. The leather is stitched around the ball w
The density of substances quantify the mass per unit volume of a substance. This is a known intrinsic property of substances such that we can determine the mass given the volume, and vice versa, as long as we know the density.Answer and Explanation: ...
