DNA fingerprinting for those not formilliar with that wording is; Because we all have unique DNA, we can use DNA from samples to match with DNA taken from people. Like a hair sample left behind at a robbery, like a fingerprint.

If I have a 8.345x10-3 moles in .05L of solution, I have .1669M right? Now, if the pH is 4, then is the formula for Ka is:
(10x-4)(10x-4)/.1668?

Then how do I calculate the Ka after I've added, say, .005L of a base of .4M?

A rock is dropped from the top of a 45m tower and at the same time a ball is thrown from the top of the tower in a horizontal direction. Air resistance is negligible. The ball and the rock hit the level ground a distance of 30m apart. The horizontal velocity of the ball thrown was almost nearly....?
I know the answer is 10 m/s but why? Can someone explain how you get the answer?
thanks

Part 1: A geometric progression has first term a (where a>0), and common ratio r. The sum of the first n terms is S(n) and the sum to infinity is S. Given that S(2) is twice the valus of the fifth term, find the value of r. Hence, find the least value of n such that S(n) is within 5% of S.

Part 2: It is given that the solution set of 1/(1+x)

Full ?
Electrical Systems are governed by Ohm's law, which states the V=IR, where V=voltage, I=current, and R=resistance. If the current in an electrical system is decreasing at a rate of 8 A/s while the voltage remains constant at 10V, at waht rate is the resistance increasing when the current is 56 A? Please provide steps/explanation. THANK YOU!
