The charge on an object that contains 8.41 x 10^19 excess protons is given by the formula: Charge = (Number of protons) x (Elementary charge) Given that the elementary charge is approximately 1.6 x 10^-19 coulombs, the charge on the object can be calculated as follows: Charge = 8.41 x 10^19 protons x 1.6 x 10^-19 C/proton Charge = 13.456 x 10^0 C Therefore, the charge on the object is 13.456 coulombs.

k M(t) Question PSS10-Q1. The system shown in the figure below is composed of: \begin{itemize} \item One disc of radius $r = 0.5$ m, mass $m_1 = 3$ kg moments of inertia $I_1 = 0.375$ kg\text{-}m^2$, with respect to its centre and centre of mass, which is pinned to the ground. The disc rotates about its centre and the quantity $\theta_1$ defines its rotation angle (positive CCW). \item A second disc of radius $r = 0.5$ m, mass $m_2 = 5$ kg moments of inertia $I_2 = 0.625$ kg\text{-}m^2$, with respect to its centre and centre of mass, which is pinned to the ground. The disc rotates about its centre and the quantity $\theta_2$ defines its rotation angle (positive CCW). \item A point mass $m_3 = 1$ kg, constrained to move only vertically. \end{itemize} A torsional spring of stiffness $k_t = 10$ N\text{-}m/rad connects the first disc to the ground, and a flexible cable of stiffness $k = 100$ N/m connects the two discs. All springs are unstretched for $\theta_1 = 0$ and $\theta_2 = 0$. An inextensible cable connects the second disc to the point mass. An external moment $M(t) = M_0 \cos(\omega t)$ is applied to the second disc, with $M_0 = 0.3$ N\text{-}m and $\omega = 4$ rad/s. At home, you can complete the following parts a) Show that $\theta_1 = -0.4905$ rad and $\theta_2 = -0.6867$ rad is a stable equilibrium position b) Show that mass and stiffness matrices are: $M = \begin{bmatrix} 0.375 & 0\\ 0 & 0.875 \end{bmatrix}$ kg\text{-}m$^2$ and $K = \begin{bmatrix} 35 & -25\\ -25 & 25 \end{bmatrix}$ N\text{-}m/rad
