... The diameter of an audio compact disk is 12.0 cm. When the disk is spinning at its maximum rate of 540 rpm, what is the speed of a point (a) at a distance 3.0 cm from the center and (b) at the outside edge of the disk, 6.0 cm from the center? Consider two points A and B on the rotating compact disk ...

... We note that the magnitudes of FB and FL are equal according to Coulomb’s law (Equation 18.1), since the sides of the square have equal lengths and the charge magnitudes are q and 0.70 C in each case. We also note that the directions of FB and FL are perpendicular. Thus, the resultant of FB and FL ...

... Patty was riding in her brother Chuck’s car at a city speed of 15.0 m/s. Patty thought that the speed was fairly slow, so she did not bother wearing a seatbelt. She figured that she could use her arms to exert a stopping force before she hit the dashboard 0.75 m away. Chuck’s attention was diverted ...

Fundamental Study on Body Hair Movement in ELF Electric Field
... calculated using Eq.(2). Figure 5 shows the result. The electric force increases almost linearly as the dielectric constant increases. The rate of this increase is common in both cases of small and large initial angle of the hair. However, the magnitude of the electric force is different between the ...
