Answer:
Acceleration due to gravity will be
Explanation:
We have given length of pendulum l = 55 cm = 0.55 m
It is given that pendulum completed 100 swings in 145 sec
So time taken by pendulum for 1 swing
We have to find the acceleration due to gravity at that point
We know that time period of pendulum;um is given by
So
Squaring both side
So acceleration due to gravity will be
Answer:
Professor Hawking had just turned 21 when he was diagnosed with a very rare slow-progressing form of ALS, a form of motor neurone disease (MND). He was at the end of his time at Oxford when he started to notice early signs of his disease. He was getting more clumsy and fell over several times without knowing why.
