Question

Cum il scot pe $c_{2}$?Va rog
$m_{3} c_{2}( T_{3} - T) = m_{1} c_{1} + m_{2} c_{2} (T- T_{1} )$
$c_{2}=?$

Answer 1

[tex]\displaystyle m_3\times c_2\times(T_3-T)=m_1\times c_1+m_2\times c_2\times(T-T_1)\\ \\ m_3\times c_2\times(T_3-T)-m_2\times c_2\times(T-T_1)=m_1\times c_1\\ \\ c_2\times[m_3\times(T_3-T)-m_2\times(T-T_1)]=m_1\times c_1\\ \\ c_2\times[m_3\times(T_3-T)+m_2\times(T_1-T)]=m_1\times c_1\\ \\ c_2=\frac{m_1\times c_1}{m_3\times(T_3-T)+m_2\times(T_1-T)}[/tex]
