Ineed with questions 1-4 and
question 1: explain why scientists named the new pigment yinmn?
question 2: how do we get pigments that are used to color materials like paint and plastics
question 3: do pigments of the same color have all of the same properties?
question 4: what are two characteristics of yinmn that make it more advantageous to use than cobalt blue? explain why these characteristic are important?
and it’s very hard and i’m struggling with it and if you need to see the picture big then click on it and it will be big

1.Scientist named the new pigment YInMn because it contains yttrium, indium and manganese elements. The symbol for yttrium is Y, indium is In and that for manganese is Mn thus, to reflect the chemical composition of pigment it is named YInMn.

2.The pigment that is used in coloring materials like paint and plastics was discovered accidently by scientists in an experiment due to mixing and heating of chemicals while manufacturing electronics. An intense blue colored compound results due to chemical combination of two or more elements.

3.No, pigments with same color do not have all the same properties. YInMn blue and cobalt blue, both are same in color, but they have different manufacturing process and YInMn is more durable than cobalt because it gets fade over time.

4.The two characteristics of YInMn are good pigment and use of nontoxic ingredients in manufacturing. It is difficult to find the blue pigments in nature, it is also difficult to manufacture them therefore, the mentioned characteristics are important.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
