Vaginal rugae are believed to yield important clues as to the str\uctural integrity and hormonal status of the lower genital tract. We have demonstrated that use of a 10 cm visual analog scale renders reliable intra- and interexaminer results.
OBJECTIVE: To study the motion of an object traveling up and down a ramp in the absence of friction and drag forces. To measure the acceleration of such an object and see how the acceleration depends on the ramp angle.THEORY: If an object falls straight down and air resistance is small, we found in the last experiment that it accelerates down at 9.8 m/s2.an you think of different ways that the acceleration, a, might depend on the angle, ï±ï¿ï ï Remember that we do expect. a = 0 m/s2 at ï±ï ï½ï 0o and a = 9.8 m/s2 at ï±ï ï½ï 90o. a(() = ??? In this experiment we will try to come up with an empirical (based on experimental data rather than theory) relationship for a(()ï©.
first they learn that all true roller coasters are completely driven by the force of gravity and that the conversion between potential and kinetic energy is essential to all roller coasters second they consider the role of friction in slowing down cars in roller coasters always move the fastest at the bottoms of hills this is related to the first concept in that at the bottom of hills all of the potential energy has been converted to kinetic energy which means more speed
