One astronomical method used that provided an insight about the universe is the LIGO (the Laser Interferometer Gravitational Wave Observatory). This method helps us detect gravitational waves emitted by astronomical bodies. The finding of gravitational waves will lead into understanding the behavior of other bodies that we did not know exist. The consequences are; one, we can measure the activity between two bodies in orbit in the universe, two, scientist can estimate the merging of two bodies in the universe every 15 minutes by using.

Suppose that two stars in a binary star system are separated by a distance of 80 million kilometers and are located at a distanc
jonny [76]

Answer: 1) Angular separation equals 0.0000031 degrees

2) Angular separation in arc -seconds equals 0.011156"

Explanation:

For 2 stars separated by a distance 'S' and at a distance 'D' from the earth the angular separation in radians is given

\theta _{rad}=\frac{S}{D}

Applying values we get

\theta _{rad}=\frac{80\times 10^{6}}{150\times 9.46\times 10^{12}}\\\\\therefore \theta _{rad}=\frac{1}{18487500}radians

Now we know that 'π' radians equals 180 degrees thus the above value in degrees shall be equal to

\therefore \theta _{degrees}=\frac{1}{18487500\times \pi }\times 180^{o}=0.0000031^{o}

2)

The angular separation in arc- seconds is given by

\theta ''=\theta ^{o}\times 3600\\\\\theta'' = 0.0000031\times 3600=0.011156"

I found a bed bug in my room. I told my mom and she blamed me Bc my room wasn’t clean. Yeah, I been not cleaning up. And she thi
babymother [125]

Answer:

I don't think it was because your room wasn't clean. The main cause of bed bugs is travel, which means most likely you got one on you when you went outside or something, and you accidentally got it into your room. Bed bugs hitchhike on luggage, clothing, people, etc.

If there are blood stains or dark/rusty spots on your bed/pillow, there are definitely bed bugs. The bloodstains/spots come from you crushing the bed bugs accidentally. The place where bed bugs are (in this case, your room), may also begin to smell bad. You might also see eggs laid by the bed bugs.

Let me know if you have any other questions. Good luck!

If the region rises in population it will most likely cause a bigger scarcity in water, which may lead to a drought. A drought can ruin crops and leave land dry.
