Total Energy of an Simple Harmonic Motion is given as

1/2m(wA)^2

Kinetic energy for any Simple Harmonic Motion can be written as

1/2 m(wA)^2 cos^2(wt).

so for 75% KE,

3/4 * 1/2 m(wA)^2=1/2 m(wA)^2 cos^2(wt)

=> ((3)^1/2)/2=cos(wt)

we get , wt = pi / 6

w=2 pi/T

t=T/12 =

Thework done on the object =change in potential energy + friction loss

WeWork done on the object equal to 300 joules.

Increase in potential energy equal to MgH=200

Therefore substituting the value in the equation we get the frictional loss equal to 100 joules.

All the best.

Thank you.

Hello aspirant

I can help you with better information.kcet exam carry both 1st and 2nd year of puc syllabus.you are weak in chemistry then go for other 2 subject more then only you can get good score and try to read and practice problems chemistry  also 

Hope helpful to you

The chemical which is least soluble among the above four is 

Let me give you the solubility of all the chemical mentioned... 

->BeF2 : is soluble in water due to evolution of large hydration energy, when it is dissolved in water, which is sufficient enough to overcome the lattice energy

After CAT exam every IIM prepares a merit list to call students for next round of interview and WSAT which is based on your aggregate score of many factors such as CAT marks, 10th 12th and Graduation percentage, work experience, engineer or non engineer, Gender with different weightages for different
