What is the equation of motion of a pendulum whose length is 20 cm, and starts with zero initial velocity from an angle of π/3 radians?.

Acurve connects the data points that are plotted. (physical science chapter 11 motion)

Consider two metallic rods mounted on insulated supports. one is neutral, the other positively charged. you bring the two rods close to each, but without contact, and briefly ground the the neutral rod by touching it with your hand. show answer correct answer what would be resulting charge (if any) on the initially neutral rod

How are calculation for velocity and speed different
