PQR - What does PQR stand for? The Free Dictionary

Jun 18, 2010 A long wire PQR is made by joining two wires PQ and QR of The wire PQR is under a tension of 80 N. A sinusoidal wave-pulse of amplitude 3.5 cm is sent along the wire PQ from the end P. No power is dissipated during the propagation of the wave-pulse. Calculate (a) The time taken by the wave-pulse to reach the other end R of the wire. A long PQR is made by joining two wires PQ and QR of equal Answer to: A long PQR is made by joining two wires PQ and QR of equal radii PQ has length 4.8 \ m and mass 0.06 \ kg. QR has length 2.56 \ m and New Code Requirements for Calculating Heat Input

Abnormalities of P Waves, QRS Complexes and T Waves

The wire PQR is under a tension of 80 N. A sinusoidal wave-pulse of amplitude 3.5 cm is sent along the wire PQ from the end P. No power is dissipated during the propagation of the wave-pulse. Calculate (a) The time taken by the wave-pulse to reach the other end R of the wire.

The R wave is the first upward deflection that appears in the QRS complex. From leads V 1 through V 4 the R wave normally increases in amplitude and duration. Loss of this normal progression is indicative of loss of left ventricular muscle mass. The S wave is a downward deflection that follows the R wave and also reflects ventricular mass.
