Explanation Given data: The refractive index of sodium fluoride is 1.33. Formula used: Consider the formula for critical angle. θ c = sin − 1 ( n medium 2 n medium 1 ) (1) Here, n medium 2 is the refractive index of medium 2, and n medium 1 is the refractive index of medium 1. Explanation: Modify FIGURE P18.23 as shown in Figure 1. As one medium is sodium fluoride (NaF) and the other medium is air. As the light rays moves from a denser medium to a rarer medium so there will be a critical angle θ c . Modify equation (1) for air and NaF medium. θ c = sin − 1 ( n air n NaF ) Here, n air is refractive index of air medium, which has the standard value as 1,and n NaF is refractive index of sodium fluoride medium, which is 1.33. Substitute 1 for n air , and 1.33 for n NaF , θ c = sin − 1 ( 1 1.33 ) = 48.75 ° From the figure we know that; sum of all the angle in a right angled triangle is 180 ° , θ 1 + θ c + 90 ° = 180 ° θ 1 = 90 ° − θ c Substitute 48

For each of the actions depicted below, a magnet and/or metal loop moves with velocity v→ (v→ is constant and has the same magnitude in all parts). Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why. Please fully explain why it's clockwise, Thank you

A planar double pendulum consists of two point masses \[m_1 = 1.00~\mathrm{kg}, \qquad m_2 = 1.00~\mathrm{kg}\]connected by massless, rigid rods of lengths \[L_1 = 1.00~\mathrm{m}, \qquad L_2 = 1.20~\mathrm{m}.\]The upper rod is hinged to a fixed pivot; gravity acts vertically downward with\[g = 9.81~\mathrm{m\,s^{-2}}.\]Define the generalized coordinates \(\theta_1,\theta_2\) as the angles each rod makes with thedownward vertical (positive anticlockwise, measured in radians unless stated otherwise).At \(t=0\) the system is released from rest with \[\theta_1(0)=120^{\circ}, \qquad\theta_2(0)=-10^{\circ}, \qquad\dot{\theta}_1(0)=\dot{\theta}_2(0)=0 .\]Using the exact nonlinear equations of motion (no small-angle or planar-pendulumapproximations) and assuming the rods never stretch or slip, determine the angle\(\theta_2\) at the instant\[t = 10.0~\mathrm{s}.\]Give the result in degrees, in the interval \((-180^{\circ},180^{\circ}]\).
