B. Upwelling brings cold nutrient rich water to the surface and boosts aquatic life
Answer:
Constante de resorte, k = 19.745 N/m
Explanation:
<u>Dados los siguientes datos;</u>
Masa, m = 2 kg
Periodo, T = 2 segundos
Para encontrar la constante del resorte, k;
Dónde;
- T es el período.
- m es la masa del objeto.
- k es la constante del resorte.
Haciendo k el tema de la fórmula, tenemos;

Sustituyendo en la fórmula, tenemos;




<em>Constante de resorte, k = 19.745 N/m</em>
