Answer:
8.575 m
Explanation:
speed = distance/time
distance -- 2d
343 = 2d/0.05
2d = 17.15
d = 17.15/2
d = 8.575
Thenks and mark me brainliest :))

Answer:
Zero, the support force and gravitational force together equal a zero net force
Explanation:
Answer:
1. λ = 5.60 m
, 2. T = 5.80 s 3. v = 0.966 m/s 4. A = 0.315 m
Explanation:
1. The definition of wavelength is the distance between two consecutive maximums or minimums, so that the wave is repeated, in this case they give us the distance between two consecutive maximums, therefore
λ = 5.60 m
2. the period is the time it takes for the wave to start repeating itself, going through the same point. They give time to go from the highest point to the lowest point, which is the time for half a wavelength, so the time for a wavelength is
T = 2 t
T = 2 2.90
T = 5.80 s
3. For all waves the speed is the product of the wavelength by the frequency and the frequency is the inverse of the period
v = λ f
f = 1 / T
v = λ / T
v = 5.60 / 5.80
v = 0.966 m / s
4. The amplitude of the wave is the value of the zero displacement point to the maximum displacement point, give the value between the maximum and minimum displacement
A = d / 2
A = 0.63 / 2
A = 0.315 m
