Figure 1 is an energy flow diagram for an electric food blender.

An energy flow diagram for an electric food blender. A main horizontal arrow starting from the left represents 600 J of electrical energy supplied per second. This arrow splits into two paths: a straight horizontal branch representing 420 J of useful kinetic energy transferred to the blades per second, and a downward-pointing curved branch representing wasted energy transferred to the surroundings per second.

Calculate the amount of energy wasted (lost to the surroundings) in one second.
