Answer: Sirius, the brightest star in the sky, is 2.6 parsecs (8.6 light-years) from Earth, giving it a parallax of 0.379 arcseconds. Another bright star, Regulus, has a parallax of 0.042 arcseconds. Then, the distance in parsecs will be,23.46.
Explanation: To find the answer, we have to know more about the relation between the distance in parsecs and the parallax.
<h3>What is the relation between the distance in parsecs and the parallax?</h3>
- Let's consider a star in the sky, is d parsec distance from the earth, and which has some parallax of P amount.
- Then, the equation connecting parallax and the distance in parsec can be written as,


<h3>How to solve the problem?</h3>

- Thus, we can find the distance in parsecs as,

Thus, we can conclude that, the distance in parsecs will be, 23.46.

Carbon dioxide or CO2 because when we breathe out thats what we release, and CO2 cant re-enter our body. Thats why people evantually run out of air in tight spaces, Because they turn all the air into CO2
Answer:
The equation of simple harmonic motion is 
Explanation:
Given that,
Amplitude = 5 inches
Frequency 
As per the question initial displacement is zero at t = 0 for sine curve.
The displacement is zero so the phase difference will be zero.
We know that,
The general equation of simple harmonic motion

Where, A = amplitude
= angular frequency
= phase shift
We need to calculate the time period
Using formula of frequency


Put the value into the formula


We need to calculate the angular frequency
Using formula of angular frequency


Put the value into the general equation

Hence, The equation of simple harmonic motion is
