Water waves of wavelength 4m are produced by two generators S1 and S2.
Each generation when operated by itself produces waves which have an amplitude A and P which is 3m from S1 and 5m from S2.
When the generator are operated in phase, what is the amplitude of oscillation at P?
A. 0
B.1/2A
C. A
D.2A
»»answer is A. I just need the reasoning :)

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
