What experimental evidence led to the development of the atomic model from the one before it

What are the applications of electromagnetic waves

If y gets smaller as x gets bigger and y have an relationship?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
