A car engine uses the combustion of fuel to move a system of gears that
move its wheels. Not all of the fuel's energy is transferred to the wheels.
Which two transformations happen to the rest of the energy?
I A. It is transformed into sound energy.
O B. It is transformed into thermal energy.
I c. It is transformed into chemical energy.
D. It is transformed into nuclear energy.
E. It is transformed into kinetic energy.
Answer:
A and B
Explanation:
When a car engine uses the combustion of fuel to move a system of gears that move its wheels, the fuel's energy is transferred to the wheels and the rest of the energy: is transformed into sound energy and thermal energy. So, option (A) and (B) are correct.
What is law of conservation of energy?Energy cannot be created or destroyed, according to the rule of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present. The law of energy conservation is adhered to by all energy forms.
In a nutshell, the law of conservation of energy asserts that the system's total energy is conserved in closed systems, or systems that are separated from their environment.
When car engine uses the combustion of fuel to move a system of gears that move its wheels, maximum of its energy transformed into kinetic energy and rest of energy is dissipated in a form of sound energy and thermal energy. So, option (A) and (B) are correct.
