In a do‑nothing machine, two sliders are confined to perpendicular channels and are connected by a rod. the rod can be rotated, causing the sliders to move back and forth in their respective channels. suppose that the channels line up with the x‑ and y ‑directions and that the slider in the x ‑channel has velocity vx at some instant. let theta be the instantaneous angle of the connecting rod with respect to the x ‑direction. the length of the rod between the two sliders is l. find an expression for the instantaneous velocity vy of the slider in the y‑channel. express your answer in terms of vx, l, and theta.

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
