C a glass eye is my best guess because its all glass and a fake eye not actually working so thats my theroy.
Answer:
1) The block of wood is at rest.
2) Weight and Normal Reaction (see attached diagram).
Explanation:
<u>Assumptions</u>
- The block of wood is a particle (a body whose mass acts at a point, so its dimensions don't matter).
- There are no other external forces involved.
<u>Question 1</u>
"At rest" or "resting" means that the <u>object isn't moving</u>.
Therefore, the block of wood is at rest.
<u>Question 2</u>
Forces that are acting on the block of wood:
- <u>Weight (W)</u>: Due to the particle's mass, m, and the acceleration due to gravity, g: W = mg
(Weight always acts downwards).
- <u>Normal Reaction (R or N)</u>: The reaction from a surface.
(Normal Reaction is always at 90° to the surface).
See attached diagram.
Answer:
As anything that has mass and takes up space. Matter is found in 3 major states; solid, liquid and gas. Atoms are the smallest particle of matter. They are so small that you cannot see them with your eyes or even with a standard microscope.
Have a good day! :D
Explanation:
Automobiles rust faster in wet climate because the chemical reaction between the metal and the iron, oxygen or water
breaks down, or oxidizes, the metal causing the appearance of rust.
Electrons in an insulator do not move readily. This is because insulators are objects whose internal electric charges do not flow freely. They impede the flow of electrons from one atom to another atom, thus restricting the flow of electricity. Insulators are electrically inactive and the are used to stop the flow of electric current.
