-- If it's a toaster oven or the oven in an electric stove,
then it changes to thermal (heat) energy inside.
-- If it's a microwave oven, then it changes to light energy
when you open the door and the light goes on, also to
mechanical energy to turn the turntable, also to electromagnetic
(radio-wave) energy to do the cooking.
Notice that the microwave oven does NOT use heat to do
the cooking. It just shoots radio waves into the food, and
when the radio waves hit the water and fat molecules in
the food, those make the heat.
Answer:
Lubrication
Explanation:
People oil/lubricate bicycle chains because the chain turns around the cogs and rub together so this help with friction.
Hope this helps :)
Answer:
A=0.199
Explanation:
We are given that
Mass of spring=m=450 g=
Where 1 kg=1000 g
Frequency of oscillation=
Total energy of the oscillation=0.51 J
We have to find the amplitude of oscillations.
Energy of oscillator=
Where 
=Angular frequency
A=Amplitude
Using the formula
Hence, the amplitude of oscillation=A=0.199
