Answer:The acceleration due to gravity g is inversely proportional to the square of the radius in the formula g = GM / R^2 where G is the gravitational constant = 6.67 x 10^-11 Nm^2/kg^2, M is the mass of the Earth and R is the radius of the Earth

Explanation:
The triple beam balance is used to measure masses very precisely; the reading error is 0.05g
Answering the question, three examples of ways that physicists model the physical world include:
- Diagrams
- Equations
- Computer simulations
Computer simulations refer to the reproduction of behavior of a system with the use of a computer to simulate the results of a mathematical model that is linked with the system.
<h2>Further Explanation</h2>
Computer simulations are a tool that is very useful for mathematical modeling in various natural systems in physics.
Physicists write the rule of our universe using equations. Equations are an aspect of one of the models used by physicists to explain a particular situation.
Physicists use a diagram to convey information. It is a symbolic representation of information with the use of visualization techniques. Diagram provides other means for people to better understand information and process its importance.
Physics predictions about the physical world mainly depend on numerical stimulation, mathematics and empirical observations and Physicists models the physical world based on invariances and laws which are built on mathematical models.
The purpose of physics is to explain or describe everything around us. It described virtually everything around us accurately by deploring the law of physics.
However, physics is considered a natural science because it is based on mathematical analysis which is geared towards findings qualitative physical law for the physical world.

The equation of the motion of this object is ![\mathbf{y = 3 cos \Big [ \dfrac{ \pi}{2}(t -2) \Big ] }](https://tex.z-dn.net/?f=%5Cmathbf%7By%20%3D%203%20cos%20%5CBig%20%5B%20%5Cdfrac%7B%20%5Cpi%7D%7B2%7D%28t%20-2%29%20%5CBig%20%5D%20%7D)
<h3>What is oscillation?</h3>
An oscillation in a waveform is a periodic set of vibrations an object in the medium produces.
From the parameters given:
- The spring is pulled 3 feet down ward from the origin(equilibrium position) = -3
- Time to complete one oscillation = 4 seconds
The angular velocity can be computed by using the formula:
The amplitude A from the oscillation is:
It implies that the vertical shift (D) is:
However, by using the formula of the general form of a sinusoidal equation, we have:
![\mathbf{y = A cos \Big [ \dfrac{2 \pi}{4}(t -2) \Big ] + 0}](https://tex.z-dn.net/?f=%5Cmathbf%7By%20%3D%20A%20cos%20%5CBig%20%5B%20%5Cdfrac%7B2%20%5Cpi%7D%7B4%7D%28t%20-2%29%20%5CBig%20%5D%20%2B%200%7D)
