An ideal transformer has a 100-turn primary and 200-turn secondary. The primary is connected to a 110 V, 60 Hz source. The secondary winding supplies a load at 2 A at a lagging power factor (pf) of 0.85. Determine,

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
