The speed at which a grandfather clock runs is controlled by a swinging pendulum. a) If you find that the clock loses time each day, what adjustment would you need to make to the pendulum so it will keep better time? b). If the pendulum currently is 15 cm, by how much would you need to change the length to make the period lesson by 0.04s? Use scientific notation rounding to the nearest hundredth.
