Which spoon handle would get hot the quickest when the spoons are placed in a warm pan of hot water? the steel spoon the glass spoon the plastic spoon the wooden spoon6. A pendulum swings from its highest point,where it has maximum potential energy, to its lowes it has maximum kinetic energy. If the total mechanical energy in the system is 500J how much loes the pendulum have at the lowest point?PREV 180181182183184185186187188 NEXT
