An alpha particle (α𝛼), which is the same as a helium-4 nucleus, is momentarily at rest in a region of space occupied by an electric field. The particle then begins to move. Find the speed of the alpha particle after it has moved through a potential difference of −3.45×10−3 VV . The charge and the mass of an alpha particle are qα𝑞𝛼 = 3.20×10−19 CC and mα𝑚𝛼 = 6.68×10−27 kgkg , respectively. Which of the following quantities are unknown? Select all that apply. the charge of the alpha particlethe value of the electric potential at the final position of the alpha particlethe difference in potential between the initial and final positions of the alpha particlethe final speed of the alpha particlethe initial speed of the alpha particlethe mass of the alpha particlethe value of the electric potential at the initial position of the alpha particle

Write a MATLAB code to simulate the motion of a pendulum for t = [0:0.1: 10]. A sample code for creating a movie in MATLAB will be provided. The equation of motion for a pendulum is given by, for a small $\theta$, $\frac{d^2\theta}{dt^2} + \frac{g}{l}\theta = 0$. Note that the sign of the second term is opposite from Eq. (1). Use $g = 9.81m/s^2$ and $l = 0.5m$. Start with the initial conditions of $y_0 = 0$ and $v_0 = 0.25$ at $t = 0$ and test with different initial conditions and generate movies.
