Some cars are 100 percent efficient at converting energy from gasoline to energy of motion. true or false.

False

Explanation:

100 efficiency is a myth and is termed as an ideal system. In real life there is nothing such as an ideal system.

Every machinery, system or engine follows the conservation of energy but are not 100 percent efficient. The amount of energy produces by gasoline is not only used to carry out the mechanical work done but also dissipated in form of heat. This generated heat reduces the efficiency of the system thus not making it an ideal engine of car.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are
