Step-by-step explanation:
La frecuencia de una onda se define como el número de ciclos completos que realiza una partícula en un segundo.
f = n / t = 15 ciclos / 3 segundos = 5 ciclos por segundo o Hertz
El período de una onda es el tiempo que tarda la onda en realizar una oscilación o ciclo completo.
T = t / n = 3/15 = 0,2 segundos
Answer: B
from the first image, the opposite of B is D. so whenever its rotated somehow, D is going to fall on the opposite of B. Therefore when B is at the top, D should be at the opposite on the bottom. Thus we found our answer. B is the correct answer. others are eliminated.
Answer:
- t = 2.7 seconds
- t = 4.9 seconds
Step-by-step explanation:
<h3>Given </h3>
Function
<h3>To find</h3>
- Value of t when s(t) = 213
<h3>Solution</h3>
- 213 = -16t^2 + 122t
- 16t^2 - 122t + 213 = 0
- t = (122 ± √(-122)² -4*16*213)/2*16
- t = (61 ± √313)/16
- t = 2.7 seconds, t = 4.9 seconds
