A 350 g mass on a 45-cm-long string is released at an angle of 4.5° from vertical. It has a damping constant of 0.010 kg/s. After 25 s, how many oscillations has it completed?

The value is  

Explanation:

From the question we are told that

   The mass is  

   The length is  

    The angle is  

    The damping constant is  

    The time taken is

Generally the angular frequency of this damped oscillation is mathematically evaluated as

=>    

=>  

Generally the period of the oscillation is mathematically represented as

=>  

=>  

Generally the number of oscillation is mathematically represented as

=>    

=>    

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
