Which of the following situations is an application of the additive inverse property? Choose all that apply. A. A neutrally-charged carbon atom contains 6 positively-charged protons and 6 negatively-charged electrons. B. The average temperature in Cleveland, Ohio in December is 38∘F. On a particularly cold day last year, the temperature change was −38∘F from the previous day. C. A model rocket flies 50 meters into the air. It falls 50 meters before it hits the ground. D. The price of gold is $3.00 per ounce less than it was yesterday.

B. The average temperature in Cleveland, Ohio in December is 38∘F. On a particularly cold day last year, the temperature change was −38∘F from the previous day. CORRECT

C. A model rocket flies 50 meters into the air. It falls 50 meters before it hits the ground. CORRECT

Explanation:

The additive inverse property is the property that states that the addtiion of a number with its negative is zero: b + (-b) = 0.

Let's see every choice:

A. A neutrally-charged carbon atom contains 6 positively-charged protons and 6 negatively-charged electrons. CORRECT

6 positively'charged protons ⇒ charge +6

6 negatively charged electrons ⇒ charge -6

Total charge = +6 + (-6) = 0

The result is that the atom has a zero net charge.

B. The average temperature in Cleveland, Ohio in December is 38°F. On a particularly cold day last year, the temperature change was −38°F from the previous day. CORRECT

Temperature of a day is 38° F

Change of temperature was - 38° F

Resulting temperature: 38° F + ( -38° F) = 0

C. A model rocket flies 50 meters into the air. It falls 50 meters before it hits the ground. CORRECT

50 meters upward ⇒ +50 m

50 meters downward ⇒ -50 m

Final altitude = +50 m + (-50 m) = 0

Price of yesterday : x

Price of today: x - 3.00

This is not the application of the additive inverse property.
