A boat travels up stream in a river with a constant but unknown speed V with respect to water. At the start of this trip upstream, a bottle is dropped over the side. After 7.5 minutes the boat turns around and heads downstream. It catches up the bottle when the bottle has driffted 1 km down stream from the point at which it was dropped into water. Then the velocity of water current is?

Hi
I am trying to find significant differences in my experiment between day 1 and subsequent days (2-7) ie. 1 and 2, 1 and 3, 1 and 4 etc. I can't use ANOVA or T tests as they require factor levels to be independent of each other. My samples are in duplicate. Any suggestions on an appropriate stat. test and post-hoc test and also which program to use (SPSS or excel would be good!)
Thanks!

Find the least positive integer n such that 1/(sin 45 *sin 46) + 1/(sin 47 *sin 48) +...+1/(sin 133 *sin 134)=2/sin n. (all the angle measure is in degrees)

According to entropy law, an existance left in nature , diffuses, decomposes, molders and perishes...
i.e. if you leave a car in a forest for 2 months, you cant find it clean, bright,, but undirty, rusty..etc
if you leave an apple on earth, it decomposes after time...
How come life could evolve from a single cell to this perfection , with thousands of species without a Creator ?
