1. In the lab, a student has created an oscillator by hanging aweight from a spring. The student releases the oscillator from restand uses a sensor and computer to find the equation of motion forthe oscillator: x(t) = 0.13m cos (6.3 ?????? t + 0.14 radians)Thestudent ? then replaces the weight with a weight whose mass, m istwice as large as that of the original weight. The student againreleases the weight from rest from the same displacement fromequilibrium. What would the new equation of motion be for theoscillator?
2. Show that if one sound is twice as intense as another, it hasa sound level of about 3 dB higher.
