The gravitational force experienced by Earth due to the Moon is <u>equal to </u>the gravitational force experienced by the Moon due to Earth.

<u>Explanation</u>:

The force that attracts any two objects/bodies with mass towards each other is defined as gravitational force. Generally the gravitational force is attractive, as it always pulls the masses together and never pushes them apart.

The gravitational force can be calculated effectively using the following formula: F=GMmr^2  

where “G” is the gravitational constant.

Though gravity has the ability to pull the masses together, it is the weakest force in the nature.

The mass of the Earth and moon varies, but still the gravitational force felt by the Earth and Moon are alike.

An ostrich lays the largest bird egg. A typical diameter for an ostrich egg at its widest part (diameter) is 12 cm (0.12 m). Sup
Vanyuwa [196]

The centripetal acceleration is the ratio of the tangential speed and the

radius of the shell.

The tangential speed of the part of the shell is approximately <u>0.12961 m/s</u>

Reasons;

The widest diameter of the egg, d = 12 cm = 0.12 m

The given centripetal acceleration, a_c = 0.28 m/s²

Required:

The tangential speed of the bird.

Solution;

\displaystyle Centripetal \ acceleration, \ a_c = \mathbf{\frac{v^2}{r}}

Where;

\displaystyle r = The \ radius \ of \ the \ egg \ shell = \frac{d}{2}

v = The tangential speed

Which gives;

\displaystyle r = \frac{0.12}{2} = 0.06

\displaystyle 0.28 \, m/s^2 = \frac{v^2}{0.06 \, m}

v² = 0.28 m/s² × 0.06 m = 0.0168 m²/s²

v = √(0.0168 m²/s²) ≈ 0.12961 m/s

The tangential speed, v = <u>0.12961 m/s</u>
