The angle of incidence and the angle of reflection are measured from the B) normal to the surface.
Explanation:
Reflection is a phenomenon that occurs when a wave hits a boundary between two mediums and bounces back into the original medium.
The direction of the wave after reflection changes according to the law of reflection, which states that:
- The incident ray, the reflected ray and the normal to the surface all lie in the same plane
- The angle of reflection is equal to the angle of incidence (
In this framework, the two angles are defined as follows:
- the angle of incidence is the angle between the incident ray and the normal to the surface
- the angle of reflection is the angle between the reflected ray and the normal to the surface
Therefore, the complete sentence is
The angle of incidence and the angle of reflection are measured from the B) normal to the surface.

It depends on how much force there both putting on the box but because it does say the correct answer is C.
The minimum coefficient of friction to avoid slippage of the coin is 0.23.
<h3>
Minimum coefficient of friction</h3>
The minimum coefficient of friction can determined from the maximum speed of the coin.
ma = μmg
mv²/r = μmg
v²/r = μg
v² = μgr
μ = v²/(gr)
μ = (ωr)²/(gr)
μ = ω²r/g
μ = (7.95² x 0.035)/(9.8)
μ = 0.23
