The "gas" is ionized and may correctly be described as a fourth state of matter - a plasma - rather than a gas. Both a gas and a plasma would expand indefinitely if not contained somehow but the ionized particles of a plasma could be controlled electromagnetically whereas a gas could not. A typical plasma is contained in an illuminated neon sign.
Answer: this statement makes sense.
Explanation:
Supernova explosion is a bright powerful explosion of the start, it takes place at the end of the cycle of a star. This explosion is caused by having too much matter in it's core, As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in a massive explosion of a supernova. During this explosion Elements heavier than iron are formed. An uranium atom is heavier than an iron atom, so uranium falls into this category of elements that comes from supernova explosion.
Answer:
They will go backwards?
Explanation:
If positive they go forward but is negative they go backwards.
<span>If you apply force (push) both books with the same energy at the same constant rate then the friction between them doesn't matter as both will move. If you push on the bottom book only, the friction between the books needs to be sufficient that the top book is carried along on the bottom book.</span>
