These equinoxes happen on or around 21 March (the spring or vernal equinox) and 21 September ( the autumn equinox ). On these dates, the noon Sun will appear directly overhead at the Equator and everywhere … WebPhysics questions and answers. A student attaches a block of mass M to a vertical spring so that the block-spring system will oscillate if the block-spring system is released from rest at a vertical position that is not the system’s equilibrium position. The figure shows three positions of the spring as it travels from point X to.
