There was a little problem in my final exam that went "Show that a conformal equi-areal map is an isometry". I invoqued the caracterisation of "conformal" that the two metrics are proportional, say by a proportionality function L: E1=LE2, F1=LF2, G1=LG2. Then I invoked the caracterisation of...

Im not sure how to use the above posts but please post back if it is okay for me to post my study guide so that yall can please help me i have it typed and my bio teacher said that he was not going over the correct answeres so i need youe help cause i really needto pass this test. i have a few...

I'm having trouble with this problem: So for this problem i used F=ma: 79g-88=79a a=8.6861m/s^2 this is the correct acceleration i believe and to find final velocity i used: Vf^2=Vi^2+2ad where d is displacement Vf^2=2(8.6861)(25) vf=20.85m/s I'm using utexas's webhw service, and the...

Homework Statement If I was to work out the sum of all the even numbers between 1000 and 2000, am I correct in saying that there are exactly 600 even numbers? Therefore, is the final answer 959400? Could someone please confirm this? Thank you. Homework Equations Sum = n/2[(2a+(n-1)d]...

I have heard that when ice mixes completely with water then the Ice will be completely melted and the temperature of the water willl actually be below 0 C, is this true?

I need some advice for where to start my project which is about Photonics band gaps. I need to write a 10 pages paper on this subject. I am sure I will be asked a lot about the subject which won't even be in my paper so I need to learn about it as much as I can. But,unfortunatelly I don't know...

Homework Statement Steam at 100°C is injected into 1.8 kg of water at 22°C in a well-insulated container, where it condenses and mixes with the existing water, reaching thermal equilibrium. If the final temperature of the well-mixed water is 25°C, what is the mass of the injected steam...
