The Doppler effect, is one effect on light which shows that it's source is moving
Whichever one has the greatest gain in speed during that time period has.
If I could see the picture or the rest of the information that goes with that
question, I could tell you exactly which one it is.
Answer:
Electrical energy; chemical energy.
Explanation:
Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.
In this scenario, electrical energy is present in the charger and the cable while we have chemical energy in the battery of the mobile phone.
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
This ultimately implies that, the electrical energy in the charger and cable is used to charge the battery of the mobile phone as chemical energy.
The block is ACCELERATING to the left, but there's not enough information to tell which direction it's moving.
