<h3><u>Answer;</u></h3>
Each will reflect at an angle equal to its angle of incidence.
<h3><u>Explanation;</u></h3>
- <em><u>When light hits a surface or a boundary it bounces of the surface a phenomenon called reflection, which is a property of waves. Reflection occurs such that the incidence angle is equal to the angle of reflection.</u></em>
- Reflection of light depends on whether the surface is smooth or rough. When the light hits a smooth surface it bounces off the surface and all the rays of light moves in the same direction, this type of reflection is called specular reflection.
- On the other hand , when right rays hits a rough surface the rays bounces off the surface and the rays move in different directions, a type of reflection called diffuse reflection.
Answer:
The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
Explanation:
Option (d) is correct.
Distance is the total path length covered by the object.
so, for distance, we add all the path lengths
Here the total distance =7+5+2 =14 km
