Question

Raportul denistatilor a doua corpuri cu volume egale este ro1/ro2=4. Ce relație exiata intre greutățile celor doua corpuri ?

Answer 1

Ro1=ro2*4=>m1/v=m2/v*4=>m1=4m2 G1=m1*g,G2=m2*g=m1g/4=>G1=4G2

Answer 2

$\it 4=\dfrac{ \rho_1}{ \rho_2}=\dfrac{\dfrac{m_1}{\mathcal{V}}}{\dfrac{m_2}{\mathcal{V}}} =\dfrac{m_1}{\mathcal{V}} \cdot \dfrac{\mathcal{V}}{m_2} = \dfrac{m_1}{m_2} = \dfrac{m_1\cdot g}{m_2\cdot g} =\dfrac{G_1}{G_2}$
