Answer:
a) transparent
b) transparent
c) opaque
Explanation:
In the first one, the light rays go completely through, so it is transparent.
The second one I'm not too sure about. It is refraction so it's going through a different material, but the fact that it went through makes me say transparent.
Last one, the light rays are reflecting off the surface so it's opaque.
Please feel free to correct me if I'm wrong. This is just my understanding
The equator is the closest part of out planet that is closest to the sun, which means that the continents closest to the equator will in turn be warmer.
Answer:
The particle will continue moving at constant velocity
Explanation:
When the particle encounters the second force of 10 N, the net force acting on the particle becomes zero, because the two forces are equal in magnitude but opposite in direction:
For Newton's second Law, the acceleration of the particle is proportional to the net force acting on it:
Therefore, since 
, the acceleration is zero (a=0) and so the particle will keep a constant velocity.
Answer:
No
Explanation:
The ball dose not have any kinetic energy or potential. Nothing is in motion or stored.
