1. Is this true or false please explain in paragraph form. The four equations of kinematics are not useful in describing vibration motion.
2. Is this true or false please explain in paragraph form. A vibrating system has maximum total energy when passing through its equilibrium position.
An electron passes through a point 3.27 cm from a long straight wire as it moves at 37.3% of the speed of light, Find the magnitude of the electron\'s acceleration at that point
A spaceship in distress sends out two escape pods in opposite directions. One travels at a speed v1 = 0.60c in one direction, What speed does the first escape pod measure for the second escape pod
