Earth's orbit around the Sun is nearly circular. The period is $1 \mathrm{yr}=365.25 \mathrm{d}$. (a) In an elapsed time of $1 \mathrm{d},$ what is Earth's angular displacement in radians? (b) What is the change in Earth's velocity, $\Delta \overrightarrow{\mathbf{v}} ?$ (c) What is Earth's average acceleration during $1 \mathrm{d} ?$ (d) Compare your answer for (c) to the magnitude of Earth's instantaneous radial acceleration. Explain.

A wheel of radius $r$ rolls to the right without slipping on a horizontal road. Its axle moves at a constant speed $v_{\text {axle }}$ (a) Find the velocities of points $A, B,$ and $C$ with respect to the axle. Express your answers in terms of $v_{\text {axle }}$ and $r,$ as needed. [Hint: In the reference frame of the axle, the wheel is rotating in place at a constant angular speed $\omega .]$ (b) Find the velocities of points $A, B,$ and $C$ with respect to the road.
(c) Comment on the velocity of point $C$ with respect to the road.

In a DNA molecule, the base pair adenine and thymine is held together by two hydrogen bonds (see Fig. 16.5 ). Let's model one of these hydrogen bonds as four point charges arranged along a straight line. Using the information in the figure, calculate the magnitude of the net electric force exerted by one base on the other.
