The figure above shows a pole with a spring around it and a 2.5kg block with a hole in the middle hanging from the spring. A light horizontal cord is attached to the block and the wall. The block is oscillating at 10.0 Hz and the standing wave shown is formed (Mr. Roberts #x27; note for the SHM test: Ignore the wave, the block/spring mechanism is in SHM and the attached string has zero effect on the SHM). The spring constant of the spring is approximately which of the following? 10 N/m 100 N/m 1000 N/m 10 N/m A simple pendulum is swinging back and forth through a very small angle, and a block is oscillating on a spring. The block-spring system takes twice as much time as the pendulum to complete one oscillation. Which of the following changes could make the two systems oscillate with the same period? Increasing the mass of the pendulum bob Increasing the angle through which the pendulum swings by a small amount Decreasing the mass of both the block and the pendulum bob Shortening the pendulum
