Does anybody know of some legitimate spell casters or practitioners in Australia? I realise that these methods are widely criticised but i have an urgent problem that requires attention and it's come to a fairly drastic point. Any information would be greatly appreciated. Thanks.

A roller coaster, (h1 = 30 m, h2 = 15 m, h3 = 25 m), is pulled up to point A where it and its screaming occupants are released from rest. Assuming no friction, calculate the speed at points B, C and D. h1= A is 30m above B. h2= B is 15m below D. h3= B is 25m below C. Help would be greatly appreciated. Thank you. If you have any questions on the view of the diagram please ask.

My teacher either doesnt word her questions right, or I'm just not getting it..

She asks:
What is an autosome? How many autosomes in a human body cell? A human gamete?

My Answer:
An autosome is a chromosome that is not involved in sex determination. There are 22 pairs of autosomes in a human cell, and 1 pair of gametes.

**Could someone tell me if this is what she wanted to hear?
---------------------
Another question is:
What is a sex chromosome? How many sex chromosomes in a human body cell? A human gamete?

My answer:
A sex chromosome is the X or Y chromosome that determines the sex of a person...(didnt finish)

**If I could get some help on that one too, it would be great!

I have 2 questions that I cannot understand. Help is greatly appreciated.
1)Physics:Uniform Motion-
A motorboat maintained a constant speed of 15mph relative to the water in going 10miles upstream and then returning.The total time for the trip was 1.5 hours.Use this information to find the speed of the current.
2)Computing Average speed
In going from Chciago to Atlanta, a car averages 45mph and in going from Atlanta to Miami, it averages 55mph.If Atlanta is halfway between Chicago and Miami,what is the average speed from Chicago to Miami? Discuss an intuitive solution. Write a paragraph defending your intuitive solution.Then solve the problem algebraically.Is the intuitive solution the same as the algebraic one?If not find the flaw.
Thanks in advance for any help.
