Which of the following describes a medical drug

Assuming A.L,

Which of the following describes a medical drug?

A) A bacterium that causes a human disease

B) A virus that is passed from person to person

C) A physiological symptom related to a sickness

D) A chemical substance used to treat disease

The correct answer is D) A chemical substance used to treat disease.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

yes? sounds right, but you didn’t ask a question.
