Chapter 2, Problem 1AC

A straight-line distance covered during a certain amount of time describes an object’s

a. speed.

b. velocity.

c. acceleration.

d. any of the above.

Expert Solution & Answer

To determine

The term used for the straight-line distance covered during a certain period of time, from the following options.

Speed

Velocity

Acceleration

Any of the above

Answer to Problem 1AC

Solution:

Option (a) is correct.

Explanation of Solution

Introduction: The speed of an object defines how fast the object is moving with respect to time. It gives the magnitude of velocity of the object.

The expression for the speed is:

speed=distance travelledtime

Explanation:

Reason for the correct option:

Refer to the expression of speed. The speed is given as the ratio of the distance travelledand the time taken. The distance travelled may be a straight line.

Hence, option (a) is correct.

Reason for the incorrect options:

Option (b) is incorrect because velocity is defined as the displacement per unit time and the displacement can be equal to or less than the distance. But, in the problem statement, it is mentioned about the straight-linedistance. So, it is a wrong answer.

Option (c) is incorrect because acceleration is defined as the change of velocity in a certain period of time. But, in the problem statement, it is mentioned about the straight-linedistance. So it is a wrong answer.

Option (d) is incorrect because options (b) and (c) are incorrect and for option (d) to be correct, all the options (a), (b), and (c) should be correct. So it is a wrong answer.

Hence, options (b), (c) and (d) are incorrect.

Conclusion:

The straight-line distance covered during a certain time period is termed as speed.

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