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.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
