Answer:
The amplitude A of the wave is the maximum displacement of the wave from the equilibrium position, which is indicated by the dotted line. In this example, the medium moves up and down, whereas the disturbance of the surface propagates parallel to the surface at a speed v. v=λT=λf.

Answer:
Y=3
Step-by-step explanation: 5x3=15, 15+3=18
6 + 3/x - 8
( six more = 6 +)
(The quotient of three and a number = 3/x)
(Decreases by eight = -8)
Answer:
Step-by-step explanation:
Look at the top triangle.
It is an isosceles triangle because two of the sides are marked equal.
The angles opposite the congruent sides are called base angles. (in the case x and z)
Base angles of an isosceles triangle are equal.
In addition, we use the Triangle angle sum theorem - the sum of the angles in a triangle is 180 degrees
60 + x + y = 180
x+z =120
but x = z so by substitution
x +x = 120
2x = 120
x = 60
z = 60
likewise for the bottom triangle:
50 +50 + Y = 180
Y = 80
