D. a and c
Explanation:
To make a generator out of a bicycle, Devon will need two magnets and coil of wire.
There is a close knit relationship between magnetism and electricity. Electricity can be generated by a wire changing flux in the presence of a magnetic field.
- The magnets provide magnetic field for the process.
- The coil of wire is placed in between the magnetic field generated by the magnets.
- The bicycle pedal is connected to the set up to turn the wire in between the magnetic fields.
- This way, electricity is produced.

Explanation:
The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.
First of all, we need to convert the energy produced from kilojoules to calories. 1 kJ corresponds to 239.1 cal, therefore:
And so now we can calculate the energy value of the oil:
