(a) when the displacement in shm is one-sixth the amplitude xm, what fraction of the total energy is kinetic energy? (b) what fraction is potential energy? (c) at what displacement, in terms of the amplitude, is the energy of the system half kinetic energy and half potential energy? (use any variable or symbol stated above as necessary.)

Explanation:

at

b) PE fraction = 1/36 = 0.02777

c) 1/2*KX^2 = 1/2*K*(A^2-X^2)

=> X = A/sqrt(2)

32: from largest to smallest, this hierarchy includes eons, eras, periods, epochs, and ages.

33: answer is c

i really hope this answer you out! it makes my day people like you and giving back to the community that has me through school! if you could do me a favor, if this you and this is the very best answer and you understand that all of my answers are legit and top notch. mark as brainliest! and have a awesome day!
