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©.
Q. A clerk moves a box of cans down an aisle by pulling on a strap attached to box. The clerk pulls with a force of 178 N at an angle of 24Â° with the horizontal. The box has the mass of 40 kg, and the coefficient of kinetic friction between box and floor is 0.45. Find out the acceleration of the box. Q. Assume you are swimming in a river while a friend watches from the shore. In calm water, you swim at a speed of 1.25 m/s. The river has a current that runs at a speed of 1m/s. Note that speed is the magnitude of velocity vector.
