A merry-go-round is spinning at a rate of 5 revolutions per minute. Cora is sitting 0.5 m from the center of the merry-go -round and Cameron is sitting right on the edge, 2.0 m from the center. What is the relationship between rotational speed of the two children?
a. Cameron's rotational speed is four times as much as Cora's rotational speedb. Cora's rotational speed is the same as Cameron's rotational speedc. Cora's rotational speed is four times as much as Cameron's rotational speedd. Cora's rotational speed is double Cameeron's rotational speede. Cameron's rotational speed is double Cora's rotational speed

Dinate system, and a charge q = - 2.00 nc is placed s2 10 n> c. (a) what is the change in electric potential energy when the dipole moment of a molecule changes its orientation with respect to es from parallel to perpendicular? (b) at what absolute temperature t is the average translational kinetic energy 32 kt of a molecule equal to the change in potential energy calculated in part(: abovethistemperature,thermalagitationprevents the dipoles from aligning with the electric field.) placed in a uniform electric field e with magnitude 1.6 * 6 on the positive x-axis at x = 4.00 cm. (a) if a third charge q3 = +6.00 nc is now placed at the point x = 4.00 cm, y = 3.00 cm, find the x- and y-components of the total force exerted on this charge by the other two. (b) find the magnitude and direction of figure p21.62 ll uu 21.55 . torque on a dipole. an electric dipole with dipole moment ps is in a uniform external electric field es. (a) find the orientations of the dipole for which the torque on the dipole is zero. (b) which of the orientations in part (a) is stable, and which is unstable? (hint: consider a small rotation away from the equi- librium position and see what happens.) (c) show that for the stable orientation in part (b), the dipole’s own electric field tends to oppose the external field. 21.62 ..
