Two balanced three-phase loads that are connected in parallel are fed by a three-phase line having a series impedance of (0.4 + j2.7)? per phase. One of the loads absorbs 560 kVA at 0.707 power factor lagging, and the other 132 kW at unity power factor. The line-to-line voltage at the load end of the line is
Compute
(a) the line-to-line voltage at the source end of the line,
(b) the total real and reactive power losses in the three-phase line, and
(c) the total three-phase real and reactive power supplied at the sending end of the line. Check that the total three-phase complex power delivered by the source equals the total three-phase complex power absorbed by the line and loads.
The uniform slender rod has a mass of m. If it is released from rest when , determine the magnitude of the reactive force exerted on it by pin B when .
To form an addition polymer, what structural feature must themonomer possess?Addition polymers are constructed from molecules that have two ormore reactive groups so ester or amide linkages arenecessary.Addition polymers are formed when alkene monomers add to oneanother, so a carbon-carbon double bond is necessary.Addition polymers are constructed from molecules that have two ormore reactive groups so a carbon-carbon triple bond isnecessary.Addition polymers are formed when alkene monomers add to oneanother, so a carbon-carbon triple bond is necessary.
