QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).
Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.
P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.

the answer C is correct i am taking it on ingenuity thanks guys i almost clicked A Hannah alright bye guys aha sorry to bug
Hey friend!
Let's figure this out
Fragmental sedimentary rocks include shale, sandstone, conglomerate, <span>salt, </span><span>breccia, </span><span>limestone, </span><span>chert, </span><span>dolomite, coal, </span><span><span>siltstone, and gypsum.
As you can see, Gneiss is not listed among examples of fragmental sedimentary rock. So your answer is B.
Hope this helps!</span></span>
A). Calculation: Given mass of Au * 1mol of Au/molar mass of Au= # of moles
;
57.01 g Au*1 mole of Au/196.97g Au=0.3 moles of Au. So the answer is 0.3 moles of gold(Au). Good luck on the rest, and message me on Brainly if you need more help. I'll be happy to.
