A bob as cliating on a pendulum the maximum height of a bob is 20cm from the equilibrium position. calculate the velocitu of abob as it passes the equilibrium position ? g=10m/s² pleas formula

5points ! is potential chemical energy always transformed into kinetic

If you mix chlorine lithium in nickel together which two elements would be the most reactive

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object
