Answer:
Option C is correct the answer.
Step-by-step explanation:
As
1 US Penny = 1 cent
As the weight of US penny = 2.500 g = 0.0025 kg
And
Option A ⇒ 5 * 10^-1 = 0.5
Option B ⇒ 5 * 10^1 = 50
Option C ⇒ 5 * 10^-3 = 0.005
Option D ⇒ 5 * 10^3 = 5000
Note: I am assuming the values mentioned in answer choices are in kilograms.
So, if the values are in grams, then:
Option A ⇒ 5 * 10^-1 = 0.5 kg
Option B ⇒ 5 * 10^1 = 50 kg
Option C ⇒ 5 * 10^-3 = 0.005 kg
Option D ⇒ 5 * 10^3 = 5000 kg
So, from all the above choices Option C i.e. 0.005 is a reasonable estimate for the weight of a u.s penny. As from all the given options, only 0.005 kg is approximately close to 0.0025 kg.
Therefore, option C is correct the answer.
