- 3 What did Franklin's kite experiment prove?
- (d) The student places the cooked potato into the jug of the food processor. The food processor contains a motor that spins blades to chop the potato. The total power input to the motor is 500 mathrm(~W) The useful power output from the motor is 300 mathrm(~W) Calculate the efficiency of the motor in the food processor. Use the equation: [ ( efficiency )=( ( useful power output ))/( ( total power input )) ] Efficiency = (e) The jug is made of plastic with a low thermal conductivity. Explain why this is an advantage.
