Question:
1) If three capacitors (5mF, 10mF, 2mF) are in series, what is the equivalent capacitance?2)1. A 50-cm-long spring is suspended from the ceiling. A 230g mass is connected to the end and held at rest with the spring unscratched. The mass is released and falls, stretching the spring by 18cm before coming to rest at its lowest point. It then continues to oscillate vertically.
a. What is the spring constant? (K=)
b. What is the amplitude of the oscillation?
c. What is the frequency of the oscillation?
2. Suppose the free-fall acceleration at some location on earth was exactly 9.8000 m/s2. What would it be at the top of a 1100-m-tall tower at this location?
