A chandelier is suspended by two identical, vertical chains side by side. The chandelier's mass is m = 6.5 kg. Part (a) If the tension in one chain is represented by T, write an expression for the magnitude of the tension in terms of m and g, the gravitational acceleration on the Earth's surface. Part (b) What is the tension in one chain, T, in newtons? Part (c) If the tops of the chains are separated so that the chains are no longer vertical, does the tension increase or decrease?

As a clinical chemist in charge of the testing of blood samples. You are required to mix a solution of sodium chloride with water in the ratio of 2:5.

=2:5

2/7 of whole solution chloride

5/7 of whole solution is water

780ml = 2/7

1/7 = 390 ml

5/7 = 1950

Total solution

=2730ml

780ml = sodium chloride

1950ml = water

780:1950ml.

How do I put that in standard form and to an appropriate number of significant figures?
