Simply put, our solar system is a speck compared to the Milky Way. Our Milky Way galaxy is a whopping 587 trillion light-years across.
So we want to know what is the age of igneous rock if it contains one half of its original amount of potassium 40. The half-life of potassium 40 is 1.251*10^9 years. Since in the igneous rock there is one half of potassium left it means only one half-life has passed. And its age is 1.251*10^9 years or 1.251 billion years.
Answer:
v=1.5081 m/s
Explanation:
<u>Uniform Circular Motion
</u>
The cork is performing a circular motion which we assume to be uniform (constant angular speed or angular acceleration zero)
The centripetal force applied to it is given by
where m is the mass and is the centripetal acceleration. This acceleration appears since the tangent speed is constantly changing direction. If w is the angular speed and r is the radius of rotation
The speed of the cork can be found with the formula
We can compute w since we know the rotation period <em>T=1.25 sec
</em>
Now, since r=0.30 m, let's compute v
And finally
Its main function is to carry information of amino acid sequences from genes to the ribosomes (where proteins are then made) in the cytoplasm.
Think of RNA as a blueprint for DNA. I hope this helped!!
