L = 2 m yüksekliğine b = 1 m genişliğe sahip bir kapak, tuzlu su ($\rho_d = 1030 kg/m^3$) ile $P_0 = 20 kPa$ etkin basınç altında tutulan bir tatlı su ($\rho_s = 1000 kg/m^3$) deposunu şekildeki gibi birbirinden ayırmaktadır. Basıncı oluşturan gazın ağırlığını ihmal ederek kapağın A noktası etrafında açılmaması için $P_0$ basıncının en az kaç olması gerektiğini bulunuz. $h_1 = 5 m$ $L = 2 m$ $h_2 = 2 m$

The standard reduction potentials ($E^o$) for the following half reactions are given. $\alpha$KGA + CO$_2$ + 2H$^+$ + 2e$^-$ $\rightarrow$ Isocitrate $E^o$ = -0.380V NAD$^+$ + H$^+$ + 2e$^-$ $\rightarrow$ NADH $E^o$ = -0.320V Which of the following is true if the full reaction is: Isocitrate + NAD$^+$ $\rightarrow$ $\alpha$KGA + CO$_2$ + NADH + H$^+$ Isocitrate has a greater affinity for electrons than does NAD$^+$. $\alpha$-KGA is reduced compared to isocitrate. NAD$^+$ is the electron acceptor, Isocitrate is the electron donor, and the reaction as written above is spontaneous at standard conditions. NADH is the oxidized form of NAD$^+$. All of the above are true.

If function s(t) gives the position of a function at time t, the derivative gives the velocity, that is v(t) = s'(t). For the given positive function, find (a) v(t) and (b) the velocity when t = 0, t = 4, and t = 7. s(t) = 16t^2 - 14t + 2. A. v(t) = ? B. t = 0; v(0) = ?, t = 4; v(4) = ?, t = 7; v(7) = ?
