Why "evolutionist" scientist Do NOT Offer Any Scientific REPLIES to the EVOLUTION DECEIT Book’s Arguments?

This book has been written to make this fact known to people. Since its first publication, originally in Turkey and then in many other countries, millions of people have read and appreciated the book. In addition to Turkish, it has been printed in English, German, Italian, Spanish, Russian, Chinese, Bosnian, Arabic, Albanian, Urdu, Malay and Indonesian. (The text of the book is freely available in all these languages at www.evolutiondeceit.com )
The impact of The Evolution Deceit has been acknowledged by standard-bearers of the opposing view. Harun Yahya was the subject of a New Scientist article called "Burning Darwin". This leading popular Darwinist periodical noted in its 22 April 2000 issue that Harun Yahya "is an international hero" sharing its concern that his books "have spread everywhere in the Islamic world."

When an earthquake occurs...?

When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 78 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far is the seismograph from the earthquake?

Two blocks are connected by a wire....?

Two blocks are connected by a wire that has a mass per unit length of 8.50 X 10^-4 kg/m. One block has a mass of 19.0 kg, while the other has a mass of 42.0 kg. These blocks are being pulled across a horizontal frictionless floor by a horizontal force P that is applied to the less massive block. A transverse wave travels on the wire between the blocks with a speed of 352 m/s (relative to the wire). The mass of the wire is negligible compared to the mass of the blocks. Find the magnitude of P.

If you understand this, can you please tell me how you did it? Thanks!

Help!!!! H/W?

A science club is wondering if a rat could take more or less time according to the size of the maze. If the maze is big enough, it'll take the rat more time to find the cheese. If the maze is small, it'll take the rat even less time to find the cheese. Is the independent variable the size of the maze? and the dependent variable is it the amount of time it takes the rat to find the cheese?
