Its the closest galaxy to us. Do you think it might strip away some of the mystery surrounding dark matter? Gravity of dark matter is believed to hold galaxies together. What's your belief? The collision might take place or it will travel around us a few times before colliding. This is centuries away.

Hey,
I have a test tomorrow and I had a few last study questions on my review.

If you kknow the posistions of a particle at two points along its path and also know the time it took to get from one point to the other, can you determine the particles instataneous velocity? its average velocity? Explain.

How to calculate average speed from a displacement time graph

A bus travels on a northbound street for 20 s at a constant velocity of 10m/s. After stopping for 20s it travels at a constant velocity of 15 m/s for 30 s to the next stop, where it remains for 15s. Finally the bus continues north at 15m/s until it makes its last stop 20s later. What is the average veloctiy of the bus for this period?

I am working with a child at the last minute on a science fair project. It is due tomorrow and lacking a lot of required information. I am unsure where the idea came from or what the steps were that were supposed to be taken. I have the outcome and so forth from his mother but not the steps etc. The project is on the effect of different types of music on plants. Has anyone ever done this project?
