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

pose an egg of this size rolls
down a slope so that the centripetal acceleration of the shell at its widest part is 0.28 m/s2. What is the tangential speed of that part of the shell?

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>

Sladkaya [172]
The main difference between the model of the atom proposed by Greek philosophers and the model proposed centuries later by Dalton is that the Greek one was mainly speculative and philosophical - it wasn't based on real evidence, but on their suggestions and thoughts about the matter. On the other hand, Dalton had the means to prove his theory using viable evidence, not just speculations.

Two balls, each with a mass of 0.5 kg, collide on a pool table. Is the law of conservation of momentum satisfied in the collisio
Dmitriy789 [7]

During the collision between two balls on the pool table there is no external force along the line of collision between them

Since there is no external force on it so here we can say

F = 0 = \frac{\Delta P}{\Delta t}

here we have

\Delta P = 0

so we can say

P_i = P_f

since there is no external force so we can say during the collision the momentum of two balls will remain conserved
