(c). With this polynomial we have four terms and the zeroes here are, Now, weâve got some terminology to get out of the way. If r is a zero of a polynomial and the exponent on the term that produced the root is k then we say that r has multiplicity k. Zeroes with a multiplicity of 1 are often called simple zeroes. For example, the polynomial will have one zero, , and its multiplicity is 2.
We'll start by looking at changes in matter, but as you'll see, it is not possible to talk about changes in matter without talking about adding or releasing energy. Matter can be changed two ways, physically and chemically. Let's discuss Physical changes first. Physical changes. Physical changes occur when matter changes from one state of matter to another state of matter by adding or losing thermal energy. In a physical change of state matter retains its original identity, it just changes the state of matter it is in. For example: Imagine a beaker of ice sitting on a warm hot plate. As you watch the ice, this solid water makes a physical change of state to liquid water.
Explain how energy can be changed from one form to another, e.g. chemical energy to heat energy. bhollist@us.ibm.com. It's important to accept that energy is an abstraction. It's not some sort of invisible stuff that flows from one object to another.xplain how energy can be changed from one form to another, e.g. chemical energy to heat energy. bhollist@us.ibm.com.
