Answer:

L=55.9m

Explanation:

The equation for the period of a simple pendulum is:

$T=2\pi\sqrt{\frac{L}{g}}$

In our case what we know is the period and the acceleration of gravity, and we need to know the length of the pendulum, so we can write:

$L=(\frac{T}{2\pi})^2g$

Which for our values is:

$L=(\frac{15s}{2\pi})^2(9.81m/s^2)=55.9m$

Answer:

The rate the radius of the balloon shrinking at the moment the radius is 5 centimeters is 0.1783 cm/s

Explanation:

Here we have

dV/dt = 56 cm³/s

$\frac{dV}{dt} = \frac{d}{dt}(\frac{4}{3}\pi r^3) = \frac{4}{3}\pi\cdot3r^2 \frac{dr}{dt}$

When the radius is 5 cm we have

$56 \hspace {0.09cm}cm^3/s= \frac{4}{3}\pi\cdot3\cdot 5^2 \cdot \frac{dr}{dt} = 314.16 \times \frac{dr}{dt}$

Therefore,

$56 \hspace {0.09cm}cm^3/s= 314.16 \hspace {0.09cm}cm^2\times \frac{dr}{dt}$

From which,

$\frac{dr}{dt} = 56 \hspace {0.09cm}cm^3/s \div314.16 \hspace {0.09cm}cm^2$

$\frac{dr}{dt} = 0.1783 \hspace {0.09cm}cm/s$

The rate the radius of the balloon shrinking at the moment the radius is 5 centimeters = 0.1783 cm/s.
