Investigation Definition and 110 Threads

Hey I am doing an investigation for logarithms, and I have a question. logx^n = nlogx. Based on previous knowledge of exponents, could someone please explain why this is true? Thanks.

Hey everyone I'm doing some investigation into how sound proofing actually works, and I'm more or less stuck. I've found two terms(http://www.soundproofing101.com) which are used to decribe what happens when you sound proof. they are: noise reduction and noise absorbtion "Noise reduction...

I was curious to what rules Police accident investigation people use to work out the speed of cars before accidents. Also an explanation of how these work would be useful as well. I have also herd but i don't know how true it is that the coefficient of friction from any make of tyre is about...

(Thanks to the guy who answered my original thread) For a physics project I'm investigating the effects on the flow rate of fluids. I'm going to find a relationship between orifice diameter and flow rate (keeping things simple I'll assume it's a circular orifice for a cylindrical can). For...

dear friends.. i am a high skool student.we have to do an investigatory project on bio and chem.. chem - food adulteration bio - cancer chem we have completed te practicals but similar to phy we have to submit 10 - 12 pages of relevant info. in case of bio we have todo on cancer.. but...

An ABC TV station, WJLA, ran a story called "The Investigation the Egg Industry Doesn't Want You to See", using footage from a group called Compassion Over Killing. It's available online at http://www.wjla.com/news/stories/0704/159474.html . It showed some really disturbing footage. It shows...

Hi! I'm a UK based student undertaking A-Level Physics. I am now in my second year completing my majour investigation. We are allowed to study and investigate any physics phenomina(sp) of our choice, I have decided upon a ball in a jet looking into the effects of Bernoulli. One of the...

Colour and heat! Hello, I am having a physics investigation about thermophysics stuff. I investigate how the rate of temperature increase inside a box alters by the colour of the box.. There are a few questions i want to ask: -a) Black box will abviously gets the hottest. But among red, blue...

hi in my physics class right now we've been told we're going to be to doing an experiment where we put a variable amount of water into a tray, hold one side up, and drop it from a variable height, thus, when it hits the table, the water will move and waves will ocsillate back and fourth...

I did this experiment with various values for (d), which is the height from the top of the string to the stop. The length of the string was 0.7m. Since i used 6 differnt values for (d) i got 6 readings. why i stated all this is because i have to find g from the following expression T =...
