The correct answer is letter C. The angle of incidence is equal to 55 degrees. This is because Specular Reflection refers to mirror-like reflection of light or other kinds of waves from a surface. This phenomenon is where light from a single incoming direction is also reflection in a single-outgoing direction.
Answer:
36watts
Explanation:
Data obtained from the question include:
R (Resistor) = 4 Ohms
V (Voltage) = 12V
P (power) =?
P = IV
Recall: I = V/R
P = V^2 /R
P = (12)^2 /4
P = 144/4
P = 36watts
Therefore, power is 36watts
The medium for an ocean wave is the ocean water which involves movement on the water body.
<h3>What is a Medium?</h3>
This is defined as a substance or material that carries the wave. In the case of ocean waves, the medium is referred to the ocean water.
The medium is not transferred when a water wave moves on a lake as energy is transported but the water molecules aren't which is why lakes have water present in them.

Answer:
Rusting of irons
Change in molecular composition
irreversible change
Explanation:
chemical change Is an irreversible change so we will only observe permanent change
The initial voltage at the primary= 750 V
Explanation:
for a transformer
Es/ Ep= Ns/ Np
Es= secondary voltage= 240 V
Ep= primary voltage
Ns= number of turns in the secondary=8
Np= Number of turns in the primary=25
so 240/Ep=8/25
Ep=750 V
