Which hormone produces an anabolic effect on protein and carbohydrate metabolism?

The system shown in the figure is released from rest. The pulley and spring are massless,and friction is absent everywhere. The speed of the $5\, kg$ block when the $2\, kg$ block leaves contact with the ground is: (Take the force constant of the spring $K = 40\, N/m$ and $g = 10\, m/s^2$)

The molar enthalpies of combustion of $C_2H_{2(g)}$,$C_{(graphite)}$,and $H_{2(g)}$ are $-1300$,$-394$,and $-286 \ kJ \ mol^{-1}$,respectively. The standard enthalpy of formation of $C_2H_{2(g)}$ is ....... $kJ \ mol^{-1}$.

In which plant was the importance of day length for flowering first observed?

The perpendicular distance from the point $(1, \pi)$ to the line joining $(1, 0^{\circ})$ and $(1, \frac{\pi}{2})$ (in polar coordinates) is:
