Suppose you are helping Galileo measure the acceleration due to gravity by dropping a canon ball from the tower of Pisa, You mea
Anni [7]

It is given that the height of the tower is

h=183 ft.

The uncertainty the measurement of this height is

\Delta h=0.2 ft

Drop time is measured as:

t=3.5s

The uncertainty in measurement of time is:

\Delta t=0.5 s

Using the equation of motion: h=ut+\frac{1}{2} at^2 where, h is the distance covered, u is the initial velocity, a is the acceleration and t is the time.

u=0 (because canon ball is in free fall). we need to calculate the value of a=g.

\Rightarrow h=\frac{1}{2}gt^2

\Rightarrow g=\frac{2h}{t^2}\\ \Rightarrow g=\frac{2\times 183ft}{(3.5s)^2}=29.87 ft/s^2

The uncertainty in this value is given by:

\Delta g=g\sqrt{(\frac{\Delta h}{h})^2+(\frac{2\Delta t}{t})^2}

Substitute the values:

\Delta g=29.87\sqrt{(\frac{0.2 }{183})^2+(\frac{2\times 0.5}{3.5})^2}=29.87\sqrt{1.19\times 10^{-6}+0.08}=29.87\times \sqrt{0.08}=29.87\times 0.28=8.44 ft/s^2

In about 5 billion years, at the end of its lifetime, our sun will end up as a white dwarf, having about the same mass as it doe
vitfil [10]
It is fine to use the equation given by Plitter, since we are told that the mass is about the same as it is now, and I seriously doubt the original question wants the student to go into relativistic effects, electron degeneracy pressure and magnetic effects that govern a real white dwarf star.
There is no need to make it unnecessarily complicated, when the question is set at high school level.  The question asks, given a particular radius, and a given mass, what will the density be (which in this case will be the average density).   To answer the question, one needs to know the mass of the sun (which is about 2×1030 Kg.  One needs to convert the diameter to a radius, and then calculate the spherical volume of the white dwarf.  Then one can use the formula given above, namely density=mass/volume
