An automobile produces 1.2\(\times\)106 J of energy by utilizing 4.0\(\times\)106 J of energy. What is the efficiency of the automobile?

Sagot :

Answer:

30%

Explanation:

Efficiency (e) is the ratio of the energy produced to the energy consumed. Efficiency is always between 0 and 1. The efficiency of the automobile is:

e = (1.2×10⁶ J) / (4.0×10⁶ J)

e = 0.3

The efficiency of the automobile is 0.3, or 30%.
