4. (20 pts) The disk is moving to the left such that it has an angular acceleration $ \alpha= $ $ 10 \mathrm{rad} / \mathrm{s}^{2} $ and angular velocity $ \omega=5 \mathrm{rad} / \mathrm{s} $ at the instant shown. If it does not slip at A, determine a) The acceleration of point $ \mathrm{C} $; b) The acceleration of point $ A $; c) The acceleration of point $ B $.

Consider a line segment of very long length with constant linearity charge density l. Calculate the electric flux through a cylinder of height L and radius R whose axis is parallel to the straight line. (Suggestion: consider d the distance of the axis of the cylinder from the straight section and distinguish the cases Rd).

Problem: Consider a microwave oven (a rectangular metal box) with dimensions of 40 x 40 x 25 cm operating at 2.45 GHz. Assume that the magnetron emits waves with the frequency width f = 10 MHz. Comments: This value f refers to an oven loaded with food, while in an empty oven the f is more than ten times lower. Q1: How many modes are excited in the microwave oven loaded with food? Take the closest integer number. Q2: Find the wavelength of the wave emitted by the magnetron in the microwave oven at f = 2.45 GHz.
