The answer is B because, the farther the goes the speed starts to decrease and stops it depends on the frequency of the wave.

A is the Helmholtz free energy. It's derivative with respect to temperature(not time), gives the entropy, S
Answer:
follows are the responses to the given question:
Explanation:
The kinetic energy of every object moving. any entity lifted against the strength of gravity stores elastic potential of gravity.
Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed . So, if KE improves, it is valid that PE declines.
If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.
Answer:
dont know what that is too much static
Explanation:
Answer:
x = A sin w t displacement in SHM
v = A w cos w t velocity in SHM
PE = 1/2 k x^2 = 1/2 k A^2 sin^2 w t
KE = 1/2 m v^2 = 1/2 m w^2 A^2 cos^2 w t
If KE = PE then
k sin^2 w t = m w^2 cos^2 w t
sin^2 wt / cos^2 w t = tan^2 w t = m w^2 / k
but k / m = w^2
So tan^2 w t = 1 and tan w t = 1 or w t = pi / 4 or theta = 45 deg
Then x = r sin w t = r sin 45 = .707 r
