You want to double the resonance angular frequency of a series R-L-C circuit by changing only the pertinent circuit elements all by the same factor.
By what factor should you change them?
What is the acceleration of a ball traveling horizontally with an initial velocity of 20 meters/second and, 2.0 seconds later, a velocity of 30 meters/second? A. 1.6 m/s^2 B. 3.0 m/s^2 C. 3.4 m/s^2 D. 5.0 m/s^2
If the sprinter from the previous problem accelerates at that rate for 20 m, what will be his time for the race
