Explanation: hope this helps
Answer:
LED ligths produce less heat and more ligth.
Explanation:
Incandescent bulbs transform 88% of their energy in form of heat, but not in ligth, however LED ligth bulbs transform 88% of their energy in visible ligth (in particular visible wavelengths), so they are more eficcients.
acceleration is considered to describe an increase or positive change of speed or velocity But deceleation is considered to describe a decrease or negative change of speed or velocity
