(a) For constructive interference the two waves will have higher amplitude of 10 cm.
(b) For destructive interference the two waves will have zero amplitude.
<h3>
Amplitude of the waves for constructive interference </h3>
For constructive interference the two waves will have higher amplitude after constructive interference.
Resulting amplitude = 5 cm + 5cm = 10 cm
<h3>
Amplitude of the waves for destructive interference </h3>
For destructive interference the two waves will have zero amplitude after destructive interference.
Resulting amplitude = 5 cm - 5cm = 0

Answer:
Cost = $ 3,995
Explanation:
Let's start by looking for the energy consumed, which is the power over time
E = P t
The power is 65 W, the time is 12 h each day, in a period of 30 days the time is
t = 12 30 = 360 h
E = 65 360
E = 23,500 W h
We reduce to KW h
1 kW = 1000 W
E = 23.5 kW h
Let's use a direct ratio rule (rule of three) to find the cost
Cost = 23.5 17.0
Cost = 399.5 c
Cost = $ 3,995
