For a wave is described by y=0.0200 sin (kx - ωt) , where , ω = 3.62 rad/s, x and y are in meters, and t is in seconds, the wavelength = 2.978
<h3>How to solve for the wavelength</h3>
What is wave speed?
This is used to refer to the speed at which a wave is moving. It is the product of frequency and wave number
Given data
y=0.0200 sin (kx - ωt)
ω = 3.62 rad/s
y are in meters
t is in seconds
k = 2.11 rad/m
k = wavenumber = 2 * pi / wavelength
wavelength = 2 * pi / wavenumber
wavelength = 2 * pi / 2.11
wavelength = 2.978

Answer:
The force generated by a single muscle fiber can be increased by increasing the frequency of action potentials
Explanation:
The force generated by a muscle fiber is the result of the shortening of the skeletal muscle, and this force is also know as muscle tension. The larger motor units shorten along with the smaller units to produce the muscle force. The time lapsed between the beginning of the action potential in the muscle and the beginning of the contraction is the latent period. Action potential is the result of the difference electrical potential as a result of passage of an impulse along the membrane of a muscle or nerve cell.
Hi. The language here looks as though it's Spanish/Portugese ??? It would help to answer the q if the q were posted in english. I speak a little spanish and french, but it's mostly guesswork.
Answer:
9800 m
Explanation:
During acceleration, given:
v₀ = 0 m/s
a = 39.2 m/s²
t = 10.0 s
Find: v and Δy
v = at + v₀
v = (39.2 m/s²) (10.0 s) + 0 m/s
v = 392 m/s
Δy = v₀ t + ½ at²
Δy = (0 m/s) (10.0 s) + ½ (39.2 m/s²) (10.0 s)²
Δy = 1960 m
During free fall, given:
v₀ = 392 m/s
v = 0 m/s
a = -9.8 m/s²
Find: Δy
v² = v₀² + 2aΔy
(0 m/s)² = (392 m/s)² + 2 (-9.8 m/s²) Δy
Δy = 7840 m
Therefore, h = 1960 m + 7840 m = 9800 m.
