Although babies are usually born with their eyes closed, they can still see color through their eye lids. This is just like if you close your eyes and point your head to â¦ ward the esun. You can see orange light through your eye lids.
Here are the laws of a simple pendulum: 1  The period of a simple pendulum of constant length is independent of its mass, size, shape or material. 2  The period of a simple pendulum is independent of the amplitude of oscillation, provided it is small.
A pendulum makes 36 vibrations in exactly 60 s. What is its (a) period, and (b) frequency? 7. How long must a simple pendulum be if it is to make exactly one swing per second? (That is, one complete vibration takes exactly 2.0 s.) 8.. If a simple pendulum whose length is 1.50 m makes 72 oscillations in 3.00 min, what is the acceleration of gravity at its location? 5. A 2500 kg demolition ball swings on a cable 17.0 m long.
