I am unable to access my mail because the new beta test mail system is denying me access. Sort it out. If your so-called programmers had been involved in the Apollo Moon missions the astronauts would have never got off the ground. In fact they would probably have died due to your rubbish programmimng!

I recently saw an interesting TV documentary called The Deep but I had to leave before it could finish. It's about fishes found in deep deep oceans. I very much would like to see it. Please tell anything you know about it.

So I have to find the concentration of lead in seawater. I prepared a 50 mL sample of seawater containing 0.1 M KCl, 50 mM HNO3 and 30 ppm HG2+. I took 15 ml of the above sample and spiked the sample with 1 ppm Pb2+ and Cd2+ to get a final concentration of 0.01 ppm Pb2+ and Cd2+. Then i spiked the sample again with the 1ppm Pb2+ and Cd2+ to make 0.025 ppm Pb2+ and Cd2+. I continued to spike the sample until I go 0.05, 0.075, and 0.1 ppm Pb2+ and Cd2+. For lead my results were:

0 ppm = -719 mV
0.05 ppm = -708 mV
0.075 ppm = -702 mV
0.1 ppm = -698 mv

The above is for the seawater sample. My standards are below:

0.05 ppm = -719 mV
0.1 ppm = -718 mV
0.5 ppm = -708 mV

Can someone please show me how to get this concentration?

The motorcylist is riding his motorcycle up and down a hill. The question was how fast can he can before he loses touch with the ground? I was told that the weight has to be more than the normal force to keep him on the ground and to determine the maximum speed and we use a zero quantity for the normal force. Why?
