Which point on the pendulum's swing represents the minimum potential energy?

Is when potential energy is at it's highest and kinetic is at it's lowest or when kinetic is at it's highest and potential at it's lowest or when it's just zero

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.

What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.
