1/10

Q2.If the total supplied energy to the fan is 250 J and 200 J is usefully transferred to the kinetic store, how efficient is the fan?

2/10

Q3.Which energy pathway is used to transfer energy from a battery to the motor in the fan (which makes the blades spin round)?

3/10

Q4.Which is the main useful energy store that fills, when an oven is turned on?
