Question 4: Military specifications often call for electronic devices to be able to withstand accelerations of 10 g. To make sure that their products meet this specification, manufacturers test them using a shaking table that can vibrate a device at various specified frequencies and Amplitudes. If a device is given a vibration of amplitude 6.1 cm, what should be its frequency in order to test for compliance with the 10 g military specification? The acceleration of gravity is 9.81 m/$2 Question 10: You need to know the height of a tower, but darkness obscures the ceiling. You note that a pendulum extending from the ceiling almost touches the floor and that its period is 16 s. The acceleration of gravity is 9.81 m/s How tall is the tower? Question 11: A simple 1.76 m long pendulum oscillates. How many complete oscillations does this pendulum make in 5.03 min? The acceleration due to gravity is 9.8 m/s 2
