Kepler's Law (3)

T² ≈ r³

The square of the orbital period ≈ the cube the distance to the sun

The farther away the planet is, the bigger the radius, the bigger the period

The volume of a balloon an be approximated by V = 4 3 π r 3 V=43πr3. If air is leaking from the balloon at a rate of 56 cubic ce

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.

Debora [2.8K]

Hi, your question was incomplete, hence I am writing down the complete question below.

Q)The displacement x of a particle of rest mass m0, resulting from a constant force m0g along the x-axis, is

x= c2/g{[1+(gt/c)2]power0.5-1}

including relativistic effects. Find the displacement x as a power series in time t. Compare with the classical result.
