I have just started and really enjoy the book but sometimes its a little confusing. At one point it is talking about whether to buy new or used machines and it doesn’t say. It talks about how you will place the machines. It also doesn’t seem professionally edited. There are a lot of typos.

quick physical science help?!!?
1: How many electrons must be added to Carbon to fill the outer shell?Eight electrons Carbon does not have an outer shell Four electrons 2: If you added Oxygen and set hydrocarbon molecules on fire, what would you get?Hydrocarbons don’t burn C3H8O2 H2O and CO2 3: Where did the “Buckyball” get its name?American engineer, Buckmkinster Fuller. 3rd allotrope of Carbon. It looks like a domed roof. 4: A little Carbon dioxide puts the fizz in soda, but too much of it in the air can do what?Traps heat in atmosphere and might raise Earth’s temperature. Could cause climate changes. A and B 5: Diamonds and graphite are both pure allotropes of Carbon. How are they different?Diamonds are clear, graphite is grey. Diamonds are hardest mineral known, graphite’s soft enough to leave a line on paper. A and B 6: A girl is standing on a washing up bowl and touching a Van der Graaf machine. What do you think is the purpose of the washing up bowl? Higher altitudes conduct electricity better So the girl can reach the Van der Graff To insulate the girl from the ground 7: Explain why the girl’s hair is standing on end (no it’s not her style, it’s to do with the charge) The static collected from the Van der Graff Soda Machine Co2 generator creates a field on the girls head that pulls her hair away from the machine. The girl’s hairs all pick up static electricity from the Van de Graaf machine and like charges repel, so each hair tries to get as far away from the other hairs as possible. The girl has metal braids in her hair that are repelled by the Van der Graff generator 8: Which sub-atomic particle has no electrical charge?They all have electrical charges Anti-matter The neutron 9: Which of the following will usually create static electricity?Rub a wet rag on a plastic comb Rub a coin with a plastic comb Rub a plastic comb with some wool 10: How does friction cause electrons to go from one material to another?It scrapes them off and deposits them on the other material It doesn’t move the electrons; adhesive forces pull off the electrons Electrons are attracted to another material because of the Periodic Table 11: What happens to a material that collects electrons on its surface?It has a negative charge It has a positive charge It shoots off sparks 12: What causes the noise of thunder?Air clapping together after it suddenly cools Friction on the rain drops The noise caused by the bright flash 13: If you were spray painting a car and the paint droplets are given a positive charge, what charge should the car be given?negative positive same charge 14: Why would less paint fall on the floor?less paint falls on the floor because the paint being of the same charge attracts itself less paint falls on the floor because its coming out with a smoother coating less paint falls on the floor because more is being attracted to the car 15: How does the special spray prevent static cling?It creates an opposite charge It makes the clothes stiff so they don’t cling It discourages the collection of charges 16: When can high voltages be relatively safe?If you wear rubber soled shoes If the amount of current (amperes) is very small If you stay more than 15 inches away 17: How can static electricity help control pollution?By preventing lightning from starting fires By cleaning particles from smoke stacks By cleaning electrons from the air 18: What is a common way to create direct current electricity?Lightning Atomic energy None of the above 19: What happens when a light burns out in a series circuit?The other lights remain lit The voltage increases dramatically The circuit is broken 20: What is the frequency of AC in the United States?60 Hertz 50 Hertz 60 cycles per minute
