Two cars are driving at the same constant speed 푣around a racetrack. However, they are traveling through turns that have different radii, as shown in the drawing. Which statement is true about the magnitude of the centripetal acceleration of each car?Answerb. The magnitude of the centripetal acceleration 푣2푟of the car at A is greater than that of the car at B, since the radius of the circular track is smaller at A.(푣2푟퐴>푣2푟퐵

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.

In 1980, alfa romeo introduced the first system to smooth a rough idle caused by ignition and camshaft timing changes.
