Figure 1 shows an electric whisk that plugs into the mains electricity supply. The whisk can mix food by spinning a beater. Figure 1 0 1 . 1 Give two energy stores that increase when the whisk is switched on.  Use the Physics Equations Sheet to answer questions 01 box .2 and 01.3. 0 1 . 2 Work is done by the whisk when it is used to mix food. Write down the equation that links power (P), time (t) and work done (W)  The power output of the whisk is 92 W. Calculate the time for the whisk to do 23 000 J of work.
