Answer:
We have the final answer as
<h2>7.14 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual density = 5.6 g/mL
error = 5.6 - 5.2 = 0.4
The percentage error is
We have the final answer as
<h3>7.14 %</h3>
Hope this helps you
Answer:
C. Fe will stay positive and increase in magnitude.
Explanation:
Coulomb's law states that the force of attraction of repulsion between two charged particles is directly proportional to the magnitude of their charges and inversely proportional to the square of the distance of separation between them.
This means that if the size of the charges are large, the force acting on them will be large as well. Also if the distance between the two charges increases the force decreases. However, the force increases when the distance of separation decreases.
Like charges repel, therefore, two negative charges brought together will repel each other, and the distance between the two charges decreases, the force will increase in magnitude. Forces of repulsion are considered positive, therefore, the force, Fe, will stay positive and increase in magnitude.
The answer is 8. atomic number: the number of protons in the nucleus of an atom.
