This is my son's first telescope and I want him to be able to see stars and other details I have tried reading up on telescopes on the internet and I'm more confused than when I started. Please give your opinion on one's you've tried personally or any information you may know also I'm open to suggestion.
Thank You

Fossil intermediaries have been found between fishes and amphibians and between reptiles and birds. In other words,

1. existing fossil records do support natural selection.
2. existing fossil records do not support natural selection.
3. existing fossil records support evolution.
4. existing fossil records do not support evolution.

What plays a big role in the process of speciation?

1. convergence
2. divergence
3. both a and b
4. none of the above

According to Darwin,

1. fossils cannot help us determine how species evolved.
2. there is overwhelming evidence from fossils that living species did not evolve from organisms that are extinct.
3. there is overwhelming evidence from fossils that many of today's living species have evolved from organisms that are extinct.
4. both a and b.

i need to figure out the specific heat of a metal
through this given information

metal mass: 27.24 g
dH20: .9973 g/mL
v(h20): ?
Ti (H2O): 23.8 C
Tf(H2O): 31.05 C
change T: 7.25 C
Ti(metal): 100.5 C
Tf(metal): 31.05C
change T(metal): -69.45 C
SH (H2O): 4.184 Jg^-1C^-1
SH(metal): ?

heat of neuatralization

Ti:26.2C
Tf: 35.51C
change T: 9.31
qrxn: ?
no. moles: ?
change Hneut: ?

if you could explain some of that that woudl be great thanks

Their confidence is so high that they decide to blow off their final exam reading period, and they go to a fraternity party in a town far away and they had a good time. So good that they don't make it back in time for their final exam. They missed the exam. In a panic, they devise a plan. They agree to tell the professor that they had a flat tire and this prevented their returning in time to take the exam. They pleaded with him, "Let us take the exam, please, this could ruin us, we promise nothing like this will ever happen again." The professor agrees and tells them to return the next morning. The two return the following morning, and the professor gives them their exam, but decides he isn't going to hang around. He has them leave their books and backpacks in the office and sends them to different rooms to take their exams. The test consists of one 5point question some molarities problem, and each answers the question, they turn the page, and the next question is a 95 point question

I'm living in the southern part of the Republic of Ireland. At 05.50 am GMT I was driving directly east on my way to work. I could see the moon clearly in front of me. I could see no other stars in the sky but I could see a very bright (non moving) object directly above and just slightly to the right of the moon. It looked incredibly bright and this was seen in a suburban area.

Was this a planet or a star and can you give me it's name, please?

i think it would be a great idea if the aircraft engineers could figure out away to use laser and fiber optics to transport electricity from place to an other instead of billions of wires ! the aicraft would weight way less, and it would take less fuel to operate them. and gravity would have least impact on them.

Find the angle theta that maximizes the area of isosceles triangle with legs l.

It shows triangle with two legs l and the theta between those two legs.

I know I have Area=1/2B*h
And I know I can split the triangle to make a statement about theta/2 but I'm stuck on how to do all this.....please help!

Why do we see spiral shaped galaxies when gravity should pull everything into a sphere? You don't see any spiral shaped planets. Infact, what is stopping gravity from pulling everything in a galaxy into one massive ball of matter?
