È, col <a href="/wiki/Lambda" title="Lambda">lambda</a>, una consonante liquida. All'inizio di parola, il ro viene scritto così: Ῥ o ῥ, con aspirazione; probabilmente questo deriva dal fatto che, in principio di parola, era pronunciato sordo. Il valore numerico assegnatogli dagli antichi matematici greci era 100. </p> <div class="mw-heading mw-heading2"><h2 id="Gli_usi">Gli usi</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rho_(lettera)&veaction=edit&section=1" title="Modifica la sezione Gli usi" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Rho_(lettera)&action=edit&section=1" title="Edit section's source code: Gli usi"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li>In <a href="/wiki/Biologia" title="Biologia">biologia</a> è utilizzata per nominare il <a href="/wiki/Fattore_di_trascrizione" title="Fattore di trascrizione">fattore di trascrizione</a> che, nelle cellule <a href="/wiki/Prokaryota" title="Prokaryota">procariotiche</a>, separa <a href="/wiki/DNA" title="DNA">DNA</a> e <a href="/wiki/RNA_polimerasi" title="RNA polimerasi">RNA polimerasi</a> interrompendo la <a href="/wiki/Trascrizione_(biologia)" title="Trascrizione (biologia)">trascrizione</a>.</li> <li>In <a href="/wiki/Statistica" title="Statistica">statistica</a> è utilizzata come simbolo dell'indice di <a href="/wiki/Correlazione_(statistica)" title="Correlazione (statistica)">correlazione</a>, ovvero la formalizzazione della <a href="/wiki/Covarianza_(probabilit%C3%A0)" title="Covarianza (probabilità)">covarianza</a>.</li> <li>In <a href="/wiki/Matematica" title="Matematica">matematica</a> indica il <a href="/wiki/Raggio_spettrale" title="Raggio spettrale">raggio spettrale</a> di una <a href="/wiki/Matrice" title="Matrice">matrice</a>.</li> <li>In <a href="/wiki/Elettrotecnica" title="Elettrotecnica">elettrotecnica</a> indica la <a href="/wiki/Resistivit%C3%A0" class="mw-redirect" title="Resistività">resistività</a>.</li> <li>In <a href="/wiki/Fisica" title="Fisica">fisica</a> è spesso utilizzata per indicare la <a href="/wiki/Densit%C3%A0" title="Densità">massa volumica</a> (cioè il rapporto massa/volume, da non confondere con il <a href="/wiki/Peso_specifico" title="Peso specifico">peso specifico</a> N/m³)</li> <li>Nella <a href="/wiki/Teoria_degli_insiemi" title="Teoria degli insiemi">teoria degli insiemi</a> può indicare una relazione di equivalenza.</li> <li>Nell'<a href="/wiki/Algebra_relazionale" title="Algebra relazionale">algebra relazionale</a> indica l'operatore di <a href="/wiki/Algebra_relazionale#Ridenominazione" title="Algebra relazionale">ridenominazione</a>.</li></ul> <div class="mw-heading mw-heading2"><h2 id="Voci_correlate">Voci correlate</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rho_(lettera)&veaction=edit&section=2" title="Modifica la sezione Voci correlate" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Rho_(lettera)&action=edit&section=2" title="Edit section's source code: Voci correlate"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Asso_di_picche_(scrittura)" title="Asso di picche (scrittura)">Asso di picche (scrittura)</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Altri_progetti">Altri progetti</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Rho_(lettera)&veaction=edit&section=3" title="Modifica la sezione Altri progetti" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Rho_(lettera)&action=edit&section=3" title="Edit section's source code: Altri progetti"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <div id="interProject" class="toccolours" style="display: none;
