Answer:
a) v = 2.9 m / s, b) A = 0.350 m, c) v = 2.9 m / s, d) A = 1.00 m
Explanation:
The oscillatory motion is described by the expression
x = A cos (wt + Ф)
the wavelength which is the distance for the wave to repeat and the frequency which is the number of times a wave oscillates per unit of time
a) In this part they ask us for the speed of the wave.
Let's use the relationship between speed, wavelength and frequency
v = λ f
For the wavelength they indicate that the distance between two crest is 6.1 m
λ / 2 = 6.10
λ = 12.20 m
They give us the period of the wave is the time it takes to return to the same point, in this case they give half a period
A / 2 = 2.10
A = 4.20 me
f = 1 / t
f = ¼, 2
f = 0.238 Hz
let's calculate
v = 12.20 0.238
v = 2.9 m / s
b) the amplitude of the wave, is the distance from zero to some maximum
2A = 0.700
A = 0.350 m
c) the speed of the wave is not function of the amplitude, so the speed is the same
v = 2.9 m / s
d) the amplitude is
2A = 0.50
A = 1.00 m
Explanation:
Convergent boundaries (where plates collide) and divergent boundaries (where plates split apart).
Explanation:
Charles's law gives the relation between volume and the temperature of ideal gas when pressure is held fixed. It states that the volume of an ideal gas is directly proportional to its temperature at constant pressure.
If the temperature of an ideal gas is doubled, its volume also gets doubled as there is a direct relation between volume and temperature.
<span>a wave in a spring and a P wave are longitudinal waves. Both waves have compression and rarefaction
