Yeah that why I was confised.. haha I was like " when did 103 kg became = 1 metric ton.." hahha Since it was in teh question I used it... anyway the answer should be.. 81600000 kg / 1000 kg = 81600 Ton

1.7 cm =.017m=thickness Width =6 km =6000m length = 8 km =8000 m t0al volume = .017 x 6000 x 8000 =81600 m^3 =81600 x (100 cm)3 =81600 x 1000000 cm^3 =81600000000 cm3 since 1cm^3 = 1 gram 81600000000 cm^3 = 81600000000 gm =81600000 kg since 1 metric ton =103 kg 81600000...

Yes sir, I did tried. But when I do...It coems to a point where I have to take inverse of log... and I don't think there is inverse function for log.. Or is there? If yes how to do in calculator? Or am i on wrong way?

I know that... But...i mean is theer any inverse log? I don't see in my calculator?

Decibel / Intensity Problem, How do I approach it? ASAP.! I have a question, I don't know how to approach it.. I couldn't find a way.. [FONT="Tahoma"]1.Suppose that the sound level of a conversation is Initially at an angry 70 dB and then drops to a soothing 50 dB. Assuming that the...

No one? ?

yeah both of them are at same direction at same speed 160 km

Does anybody know about this?

Anyone can give me more hint??

hi what will happen to teh sign on doppler's general equation when both source and dectector are moving in the same direction at the same speed.? I didnt find this on my books.? Does anyone knows? dopler equation F' = f (V +/- Vd) ------------ (V +/- Vs) ?

hmm thanks... no. 1 question is making some sense..now...haha and thnks for making it clear and on no. 2 I tried taking devitaive before with respect to time. it gives dy/dt = 15.0 cm (-sin((pi)x-15(pi)t)) * ((pi)x-15(pi))) now where a I suppiosed to plug in that given y= +12.0 cm at?

Hi thanks for your reply. But none of your hints were helpful. I mean I already know these stuff...But I wanted to know what to do after that? How to relate the given values in the problem?

Hi, I have two question...I spent 2 hrs on these two but couldn't fins out how to solve it...can anyone show me right way? hint? 1 A sinosodial wave of frequency 500Hz has a speed of 350 m/s a. How far apart are two points that differ in phase by Pi/3 rad? b. What is the phase difference...

that means I am supposed to solve for "V" right? But the answer I got is not the same as the one I got from V=w/k ??

Am i suppose to t6ake second derivative of whole equation...twice? once with respect to t and again with respect to x? is that how I am supposed to do?
