Write an equation to model how much money you have deposited after m months. Let s be the amount you have deposited. you were given $500 and it adds $10 per m month.
1. Draw the equivalent circuit of a lipid bilayer. With the externally applied voltage (V), what is the current (I) through the lipid bilayer? Write down the equation. If the applied voltage is a triangular wave (V~t relationship), what will be the corresponding current waveform like (I~t relationship)? You don't have to draw the I-t waveform; just describe the I-t wave, i.e. whether it is triangular, square or sine wave. (4p) V Triangle Time (t)
2. For the continuous Random Variables. a) If $p_{X, Y}(x,y) = 2$ for $0 < x < 1$ and $0 < y < x$, sketch and label the joint PDF. b) For this joint density, are x and y independent? c) For this joint density, Find $p_X(x)$.
l) For the schematic geared system shown in Figure Q1, refer all components to shaft ABP as an equivalent dynamic system, and hence derive the characteristic dynamic matrix in the form $[K][\theta]-[T]$. [6] ?) Determine the fundamental natural frequency and 'actual' inertia $I_C$ of 'UNIT C' to ensure the node position occurs at the gearbox. [7] ?) UNITS A and B are simultaneously subjected to periodic in-phase torques of the form $T_A = 1.0 \cos(2t)$ Nm, and $T_B = 2.0 \cos(2t)$ Nm respectively. Determine the actual amplitudes of the vibration $[\theta]$ of each component, ignoring any damping effects.
