Another General Knowledge Test - Do Not Use a Search Engine or a Book - use your brain!?

We Answered:

1. Systematic killing of large groups of people is generally frowned upon. Lack of action by the UN is even more disconcerting.
2.Antonin Scalia, Ruth Bader Ginsberg, Justice Roberts, Justice Thomas, and I could picture him but couldn't remember Justice Alito's name without looking him up. The rest of the Justices I wouldn't have got.
3. Heh. I do good to remember the names of people I meet in person. Paul Mcartney was one.
4. Name the 20th century US Presidents, in order.
<37 I can't remember in order.
37. Nixon
38. Ford
39. Carter
40. Reagan
41. G HW Bush
42. Clinton
43. GW Bush
5. Good question. I know common practice for baby stem cells is to take the raw cells from a impregnated embryo before it develops in to a human form. As I understand it, it's just cells that can become different types of cells.
6. Mercury, Venus, Earth, Mars, Saturn, Jupiter, Uranus, Pluto, Planet X (Had to look Neptune up.)
7. 365.25 days
8. Heh, I knew playing Risk would come in to good use some day.
Africa: Egypt- Cairo, Ethiopia, Sudan
Asia: China, Kyrgistan (sp), Uzbekistan, Russia- Moscow
Europe: France- Paris, Belgium- Brussels, Norway- Oslo
North America: US- DC, Canada, Mexico- Mexico City

Science Help Please Urgent!?

We Answered:

4. Why do you hear thunder after you see the lightening in a far off storm?
speed of light is much greater than that of sound.
5. Light is one type of electromagnetic radiation. Name 3 others?
radiowaves, microwaves, gamma rays,infrared waves...more than you need(make ur teacher happy)
7. Using your knowledge of sound and light, write a paragraph outlining the similarities and differences between them?
similarities-both are forms of waves, carry energy, can be detected by our senses
dissimilarites-sound waves are mechanical, need a medium of propagation,have much less speed
loght waves are electromagnetis, no medium required, very fast speed
11. A string telephone can be made from 2 metal cans and some string. Suggest why -
a) the telephone works only when the string is stretched tight.
waves dont get dampened in the string(i believe it's so)
b) the telephone does not work when a third person touches the string.
same answer...



2) Why is it that some appliances have a three-pin plug and some have a two-pin plug?
3 pin plugs are used when current may leak out from the metal case of appliance
b) Suppose a toaster has a metal case. Would you expect it to have a three-pin plug or a two-pin plug? Explain.
3 pin plug
c) To which part of the toaster would you expect the earth wire to be connected.
metal case of the appliance
3) What is the meaning of the number 15 marked on a fuse or a circuit-breaker?
must be the max. current(in amp) that would not lead to a breakdown
4) What would happen if the active wire in a double-insulated hairdryer touched the plastic case?
the plastic case would melt(it shouldnt carry current at least)
5) Light circuits usually have an 8 amp circuit-breaker, and power circuits a 15 amp one.
a) What might happen if you put an 8 amp circuit-breaker in a power circuit.
it will break easily
b) What might happen if you put a 15 amp circuit-breaker in a light circuit.
it will cause chances of fire
c) What mistake would be more dangerous, a) or b)? Why?
you knoe=w this answer now!
6) Stupid Sparky said:' fix a broken car fuse with anything - a nail, a piece of wire or a coin. It's too much trouble to get the proper fuses. And they don't blow again when you put thick wire or nails in them.' Explain why Stupid Sparky is being so Stupid?
(nice q indeed) the nail,wire or coin wnt melt easily if an xtra load of current passes therby inc. the risk of some damage....toooo stupid


PG 267

4) An electric blanket connected to the household 240 volt supply has a current of 0.5 amps flowing through it. What is the resistance of the heating element in the blanket?
resistance=potential difference/current(Ohms law)
PG 275

2) Suggest why solar cells rather than batteries are used in spacecraft?
batteries have a definite life.
3) What must be brought near a rotating coil of wire if an electric current is to be generated in the coil?
a magnet
4) Ik Jin connects a coil of wire to a galvanometer . When he pushes the south pole of the magnet into the coil, the needle of the galvanometer deflects to the right. In which direction, left or right, will the needle deflect when Ik Jin does the following:
a) pulls the south pole of the magnet out of the coil. left
b) pushes the north pole of the magnet into the coil.left
c) holds the magnet steady inside the coil.no deflection
d) holds the magnet steady and moves the coil towards the south pole of the magnet?right

6) What are the similarities between nuclear power stations and coal-burning power stations? What are the differences?
both generate electricity...
nps use energy odf radioactive materials
cbps does the chemical energy of coal

Courtney Said:

Bible is 2000 years old. Before cars, airplane, light bulb, cell phones, computers, internet. true or false?

We Answered:

The real truth is the Bible is only one publication with its roots long ago.
The Koran is another.
The problem is that the language both were wrtten in is ancient, and has been modified in the course of time.
Thus, what exactly was the original intent of the text has had to be interpreted into modern day language.
This presents anomalies, as exact interpretation is impossible.
Thus we have multiple interpretations of each. all "coloured" just as the interpreter wants it to be.
Yes, it was all written back in ancient times. But it was not written as a single book. However;
Electricity as we know it had not been discovered;
Cars, aircraft, nuclear arms were not around;
The rest have always existed. Only man's understanding of them has evolved.
Is the Bible "dated" for the modern age? Each interpretation of it believes so.
If the Bible were foolproof, there would only be one religion. The Koran is no better off.
