Achandelier is suspended by two identical, vertical chains side by side. the chandelier's mass is m 5.7 kg. 33%

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? & 33%
part (c) if the tops of the chains are separated so that the chains are no longer vertical, does the tension increase or decrease?
