There are ten, the poster is 28" by 18.5" inches, and I want the pictures to be all the same size. I also want the poster set up like this: first column, 2 pictures, second column, 3 pics, 3rd, 2 pics, and 4th 3 pics. I want spaces b/w all the pics, and no pictures can be touching the edge, there needs to be a space, albeit a tiny one. Feel free to give answers in centimeters. THIS IS NOT HOMEWORK, IT IS A REAL POSTER FOR AN EXTRACURRICULAR. Thanks.

According to Wikipedia's "red shift" article, the red shift of distant galaxies is a combination of Dopple shift, special relativity, and the stretching of each photon during the time it takes to reach the observer. If the latter is correct, it means that energy is not conserved.

I think the writer is confused about the type of coordinate system be used. Is it an expanding coordinate system, or is the distance between grid lines constant in terms of meters?

I believe the length of a laser pulse will increase over billions of years; a one nanosecond pulse will start 300 millimeters long, and after a few billion yeats, it will be twice as long. But I doubt if the individual photons will be lengthened.

Any brainiacs care to comment?

I collect fossils mainly and the quarries I frequent have massive glacial till piles.I always ckeck these if the fossil hunting sucks..I am nervous about taking it to jewler and find out no it's not and feel stupid..I am trying to find any and all info to help me before I go..It's amazing how the internet and local library have nothing on identifying a diamond.

A 90 kg fullback runs east with 4.9 m/s. He is tackled by 94 kg opponent running north with 3 m/s. The collision is perfectly inelastic.
Find the speed and dircetion of the players after tackle.

After an elastic collision, how do you find the energy lost(like mechanical energy)?
