An atom of sodium-23 (atomic number = 11) has a positive charge of +1. given this information, how many
electrons does it have? how many protons and neutrons does this atom have?

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
