(1 kilometer = 1,000 meters, 1 hour = 60 minutes, 1 minute = 60 seconds) Complete the steps necessary to convert 55 kilometers per hour to meters per second. Min 60 1,000 15.28 100 sec
Explanation:
55 kilometers per hour to meters per second
First we have to convert the kilometers to grams;
1 kilometer = 1,000 meters
This means we have;
55000 meters per hour
Converting hour to seconds;
1 hour = 60 minutes
1 minute = 60 seconds
1 hour = 60 * 60 = 3600 seconds
We divide 55000 by 3600;
55000 / 3600 = 15.28 meters per second

Explain how electron microscopes work and why some scientists might prefer to use electron microscopes instead of light microscopes.
Answer:
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes.

2. Jessica did an investigation about the states of matter. As part of the
investigation, Jessica wanted to change a liquid into a solid. What must she do to
bring about this change in state?
Jessica had to freeze liquid into solid.
What is the matter?
The matter is anything that occupies space. There are three states of matter: Solid, liquid, and gas.
The process in which a solid turned into liquid is called melting. When the liquid turns into solid is called freezing. The temperature of freezing liquid remains constant. The factors which affect the freezing point of object:
If the intermolecular force of molecules are relatively strong, the freezing point of object will be relatively high.If the intermolecular force of molecules are relatively weak, the freezing point of object will be relatively low.When water turns into ice that process is called freezing. When water turns into water vapor is called boiling. When gas turns into a solid that process is called condensation.
Therefore, Jessica had to freeze liquid into solid.

Please help! If a forensic chemist discovers evidence through examination which would prove a person guilty of a crime, why then might this person not be convicted?
Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.
I hope this helped :) If not i'm sorry!

A six row combin harvests 266 pounds of corn per min. How many bushels of corn does it harvest per hour? (Note: 1 Bu = 56 Lbs) Round to the nearest Whole Number.
Answer:
The six-row combin harvests 285 bushels of corn per hour.
Explanation:
The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, you can apply the following formula:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{a*b}{c}[/tex]
In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?
[tex]x=\frac{266 pounds*1 bushel}{56 pounds}[/tex]
x=4.75
This is, a six row combin harvests 4.75 bushels of corn per min.
So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?
[tex]bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}[/tex]
bushels of corn= 285
The six-row combin harvests 285 bushels of corn per hour.

2. A block of wood has a mass of 360 grams and a density of 60 g/cm3. What is the volume
of the block of wood?
Answer:
6cm
Explanation:
The volume of the block of wood of 360 grams has been 60 ml or 60 [tex]\rm cm^3[/tex].
The density of an object can be defined as the mass of an object per unit volume. Density plays a pivotal role in the object sinks or floats into a liquid.
If the density of an object is lighter than the density of the liquid, the object will float onto the liquid. If the density of an object is more than the density of the liquid, the object will sink in the liquid.
Density can be given by:
Density = [tex]\rm \dfrac{mass}{volume}[/tex]
Mass of the object = 360 grams
Density = 60 g/[tex]\rm cm^3[/tex]
Volume = [tex]\rm \dfrac{mass}{density}[/tex]
Volume = [tex]\rm \dfrac{360}{60}[/tex]
Volume = 60 [tex]\rm cm^3[/tex] .
1 [tex]\rm cm^3[/tex] = 1 ml
Volume = 60 ml.
The volume of the block of wood of 360 grams has been 60 ml or 60 [tex]\rm cm^3[/tex].

2. What was the primary reason in the 1850's driving the curiosity of atoms?
1905-Einstein
1827-Brown
The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.
Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.
The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.
The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.

Identify the substance oxidized and the substance reduced in the following chemical equation:zn(s)+AgNO3(aq)=Zn(No3)2+2Ag(a)
Answer:
Explanation:
zn is oxidized because its oxidation number is increased from zero in zn to +2 in zn(No3)2
Ag is reduced because its oxidation number is reduced from +1 in AgNo3 to zero in Ag
oxidation number of zn(s) is zero while the oxidation number of zn in zn(No3)2 is
zn(No3)2=x+(5*2)+(-2*6)=x+10-12=x-2
x-2+2=2
x=2
the oxidation of Ag in AgNo3
AgNo3=x+5+(3*-2)=x+5-6=x-1
x-1+1=1
x=1 while the oxidation number of Ag is zero
so zinc is oxidized and silver (Ag) is reduced
