Is cc.RigidBody deterministic for all platforms?

For example, if I have a pinball game, the ball starts dropping at position x,y, finally stops at slot 1, would the result be the same (position that the ball stops) at all platforms and browsers?

Also, would the simulation be affected by the frame rate (eg: Would there be a situation that because sometimes the device is slow and frame rate drops and hence the dt to update decreases, resulting different simulate result for same initial positions and velocities)?

Lets show the canvas, the pinball canvas:


I want the pinball bounds exactly the same way and always drop to slot 1 finally for all platforms (at least for web-mobile with all browsers), is cc.RigidBody already has this behaviour?
