When hung from an ideal spring with spring constant k = 1.5 N/m, it bounces up and down with some frequency ω, if you stop the b
Umnica [9.8K]

Answer:

L = ¼ k g / m

Explanation:

This is an interesting exercise, in the first case the spring bounces under its own weight and in the second it oscillates under its own weight.

The first case angular velocity, spring mass system is

    w₁² = k / m

The second case the angular velocity is

    w₂² = L / g

They tell us

    w₂ = ½ w₁

Let's replace and calculate

     √ (L / g) = ½ √ (k / m)

      L / g = ¼ k / m

       

      L = ¼ k g / m

Choose only one correct option. Explanation needed.
Mama L [17]

Answer:

\large \boxed{\mathrm{C. \  \  \frac{500}{7 \times 15  \times 8} \ g/cm^3 }}

Explanation:

\displaystyle \sf Density = \frac{mass}{volume}

\displaystyle \rho = \frac{m}{V}

\sf mass=500 \ g

\sf volume \ of \ a \ cuboid=width  \times length  \times height=( 7 \times 15 \times 8) \ cm^3

\displaystyle \rho = \frac{500}{7 \times 15  \times 8}
