I am doing a science fair project on how the type of mulch affects plant growth. What topics should I research, other than mulch? I don't know very much about plants, so I don't know what about plants I should research. Please help.

In one of the answers to another question someone said you can see the American Flag on the moon. I don't believe this. I don't think any earth bound telescope is powerful enough. Is it true. If it is why aren't there any pictures of it on the web.

One block (3.3 kg) is on top of a table and is connected by a massless cord over a frictionless massley pulley to another block(2 kg) which is hanging down over the right side of the table. The system starts at rest. When the masses have moved a distance of 0.431 m, their speed is 1.25 m/s. The acceleration of gravity is 9.8 m/s^2.

What is the coefficient of the friction between m2 (m subscript 2)and the table (answer in N)?

What is the magnitude of the tension in the cord (answer in N)?

Thanks in advance for your input.......

As I understand it, objects in the universe cannot be assigned an absolute position in space. Their locations can only be described in relation to other objects.

If this is the case, the two stars forming a binary star, orbiting around their centre of mass, could be considered to be stationary (relative to each other).

Why then do the two stars not fall together due to the gravitational attraction between them?

Does the fact that they don't fall together prove that there is a kind of 3D "cosmic grid" on which all objects can be located?
