The time it takes two successive crests of an ocean wave to pass a given point is called a
a) period
b) frequency
c) peak
d) amplitude

a)period

Step-by-step explanation:

a) Period is defined as the time it takes two successive crests of an ocean wave to pass a given point. It is measured in seconds.

b) Frequency is defined as the number of waves cycles that pass a point in a given time. It is measured in Hertz.

c) Peak is the highest point on the wave.

d) Amplitude is the distance between the rest position to a crest or a trough. It is measured in meters.

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
