Acceleration = (final velocity^2 - initial velocity^2) / 2 * distance
Acceleration = (19.1^2 - 9.2^2) / 2 * 32
Acceleration = (364.81 - 84.64) / 64
Acceleration = 280.17 / 64
Acceleration = 4.3777m/s^2

Answer:
#See solution for details.
Explanation:
-Chemical energy in the battery is converted into Electrical Energy which powers up the phone.
-The electrical energy is then converted to Light Energy when the phone is powered up, this is seen through the lightening up of the phone screen.
-During phone calls, the electrical energy is further converted to Sound Energy to allow for transmission of audio signals.
- As we continue to use the phone, the electrical energy is converted into heat energy which we feel due to an overheating battery.
-The cycle then repeats itself again whenever a phone is charged.
Convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat
The answer to this question is true
