What are Particle or droplets large enough to block out light spread throughout another substance?
This is known as colloidal suspension, where particles or droplets are dispersed in a substance, causing light to be scattered or blocked. Examples include fog, milk, and paint where the particles are larger than molecules but too small to settle out.
Does particles in a suspension always remain suspended?
From what I know it can't. Solubility is a physical property, but the Particle Theory of Matter only encompasses the reason as to why particles slow down when cooled and how they may take up more space, but it has nothing to do with solubility as far as I know. Sources: Finished Grade 9 Science
What type of nuclear radiation can be blocked by a block of lead Beta particles or alpha particles?
Alpha particles can be blocked by a block of lead due to their relatively low penetrating power, while beta particles may require a thicker shield, such as a piece of aluminum or plastic, depending on their energy. Lead is not as effective at blocking beta particles as it is for alpha particles.
What is a special type of mixture in which the particles of one material are scattered through another and block the passage of light without settling into layers?
A special type of mixture that fits this description is a colloid. In colloids, the particles are larger than in a solution but smaller than in a suspension, and they are evenly dispersed throughout the other substance. The particles do not settle out due to their small size and the constant movement caused by collisions with the surrounding particles.
Which radioactive particle can be stopped by a regular sheet of notebook paper?
Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead. Alpha. Beta particles are blocked by a few mm of aluminum and gamma by a few cm of lead.

What has greater mass a large block of plastic or a small block of the same size block plastic?
large block
What blocks alpha particles?
A few millimetres of lead.
Which nuclear radiation can be stopped by paper?
Alpha radiation can be stopped by paper because alpha particles are large and heavy, which makes them easier to block. Paper is thick enough to absorb the particles before they can penetrate through.
What is the building block particles of elements?
atoms
Block and teckle?
Actually, it's "block and tackle"; as in, "The block and tackle was described by Hero of Alexandria". Let's set up a block and tackle to lift these loads.
Where can you get a 2009 large block calendar template?

What is a Besser block?
A Besser block is a large double-cavity concrete block.

What are fault block?
fault block plateaus are formed when a large block of earth is uplifted
