Would a vibrating proton produce an electromagnetic wave? What a. Vibrating neutron? Explain. (protons and neutrons are particles in the nucleus of an Adam. Protons have a positive charge and neutrons have no charge)

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
