Expert Solution & Answer

Answer to Problem 18.1QQ

Option (c) the string forms a straight line.

Explanation of Solution

When two pulses travel in the opposite direction then the pulses cancel each other in terms of displacement of elements of the string from equilibrium, but the string is still moving. A short time later, a string will displaced again and the pulses will have passed each other and forms a straight line.

Thus, the string forms a straight line when two pulses completely overlap on the string.

Conclusion:

If string movement is zero and pulses cancel to each other then energy associated with pulses disappeared, which is contradictory. Thus, option (a) is incorrect.

When two pulses does not travel in the opposite direction on the string then string will not move, which is not the case. Thus, option (b) is incorrect.

The string forms a straight line because pulses continues pass each other Thus, option (c) is correct.

When the two pulses overlap in equilibrium condition and after that string does not move then pulses have vanished and will not reappear, which is contradictory. Thus, option (d) is incorrect.

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 \((-180^{\circ},180^{\circ}]\).
