The electromagnetic waves with the greatest frequency
on the spectrum are the ones we call "gamma rays".
The electromagnetic waves with the lowest frequency
on the spectrum are the ones we call "radio waves".
That's true.
Newton's law of universal gravitation says that the gravitational
force between two objects is
F = G · M₁ · M₂ / D² .
There's no note under the equation that says "only up to
this certain distance, and zero any farther than that".
The equation is true no matter how gigantic the distance
is between the objects.

Answer:
v = 4 m / s
Explanation:
In this exercise we are asked to find the speed of the wave, which is described by the expression
v = λ f
in this case the wave has 4 nodes and 3 antinodes, in a length of 12 m
for a standing wave it is satisfied that we have a full wavelength and a half of another
L = λ + ½ λ
L = λ
λ = ⅔ L
Cambien indicates that it has a frequency of
f = 0.5 Hz
we substitute
v = ⅔ L f
let's calculate
v = 12 0.5
v = 4 m / s
