The acceleration of a different speck of dust is 40 m/s.
Since the radius is been given as double and angular velocity will be constant, we can calculate the centripetal acceleration as
a = (2r)ω²
If we substitute the given values of r= 2r , and ω²= 20m/s.
Then we have

Therefore, acceleration of a different speck of dust is 40 m/s.
<h3>What is centripetal acceleration?</h3>

The length of x to the nearest tenth is; D: 38.6 m
<h3>Trigonometric ratios</h3>
The image of the triangle is missing and so i have attached it.
From the image attached, we can find the value of x by using trigonometry ratio.
We see that;
Thus;
10/x = cos 75
10/x = 0.2588
x = 10/0.2588
x = 38.64 m
Approximating to the nearest tenth gives;
x = 38.6 m

- The meaning of this excerpt is that the walk from prison to scaffolding seemed a long and treacherous journey to Hester
Scarlet letters was a book written in the Puritan Massachusetts Bay Colony from 1642-1649. The book is about a woman called Hester Prynne, who had a female child via an affair and had to live a hard life to make a new life of repentance and dignity.
