High performance engines may be designed with larger intake valves, an efficient
exhaust system, and use a supercharger to raise the volumetric efficiency for more
torque at higher rpms.​

Answer 1

1.

Using Ohm's law Resistance = Voltage / amps

Resistance = 12 /6

Resistance = 2 ohms.

2.

A vehicle could use all those, the answer is D.

3.

False, There are safety regulations used in all automotive shops., but hazardous chemicals cannot be poured down a drain. They have special containers to get rid of them.

4.

True
