    I have a computing P3 qs here! plz do help me solve it!!

    Okay so the mantissa is 01000000 and the exponent is 00000000. So if you convert that into real numbers, exponent is zero right? The mantissa would be converted into 0.1, which is equal to 0.5. Just remember that in the mantissa, the point is put after the first digit, like if the mantissa...

    physics mcqs help required URGENTLY!

    M/J08 Q24: This is a trick question. The question says "another wire of the same steel." If you read the definition of the young modulus, it is defined as having the same value if its the same material. That is why the answer is C. The young modulus doesn't change if you do not change the...

    Will Physics MCQ's repeat this year June 2011?

    Not all of them, but a couple will repeat. I've done all of the past papers from 2000-2010, and I've noticed that in the latest papers, there are usually 2-3 problems which are exact repeats of problems before 2006. But as long as you're concepts are good, you shouldn't worry ^_^

    physics mcq help

    The formula used in this question is the voltage divider rule, which is used to find voltage of a resistor in a series of resistors. R(1)/R(total) x Voltage(in) = Voltage(out) So for the top: (500/1500) x 12 = 4V For the bottom: (2000/3000) x 12 = 8V 8V - 4V = 4V Therefore, the answer is B.

    Red Sepot Biology MCQ's Booklet.

    You know, if you have actually solved all of the papers, then you don't need the book! The problems it has come from past papers, not from somewhere special. So as long as you've done all of the papers, buying the book would be a waste of money, especially since our exams are almost over.

    Chemistry Doubts

    Hydrogen bonds are formed in both Alcohols and Carboxylic acids. The reason for this is because they both have the -OH part. The oxygen is partially negative and the hydrogen is partially positive, which allows them to create hydrogen bonds. Just saying, you should try to understand WHY the...

    Chemistry MCQ Question

    Alright, I think I understand it now. By the way, doesn't the release of H2 gas also cause effervescence? So like even if CaCO3 was used, the CaO that is remaining would produce H2 effervescence in HCl :/ That's why I was thinking it could be A too

    Chemistry Paper One Problems

    Acids = pH 1-6 Neutral = pH 7 Basic = pH 8-14 Student P: Is INCORRECT because strong acids must have a pH around 1-3. The acid X has a pH of 6, which is only very slightly acidic. Student Q: Keep this in mind: Extent of dissociation is greater when an acid or base have a pH further away from...
