<span>So we want to know what is the angle of reflection of the wave if the incident angle is 40 degrees. So when the incident wave hits a surface under some angle, the reflecting angle should be the same as the angle of incidence. So the correct answer is B. 40 degrees.</span>
Answer:
Please see the attached picture for the complete answer.
Explanation:
Answer: B.
but the resistance is lower in the parallel circuit.
Explanation:
A circuit with parallel connections has a lower total resistance than the resistors connected in series. This is consistent with conservation of charge. The power dissipated by each resistor is considerably higher in parallel than when connected in series to the same voltage source.
