Answer:

<h2>The answer is 5.25 %</h2>

Explanation:

The percentage error of a certain measurement can be found by using the formula

P(\%) =  \frac{error}{actual \:  \: number}  \times 100\% \\

From the question

actual mass = 120 g

error = 120 - 113.7 = 6.3

The percentage error is

P (\%) =  \frac{6.3}{120}  \times 100 \\  = 5.25

We have the final answer as

<h3>5.25 %</h3>

Hope this helps you

Describe the photoelectric effect and explain why it made modifications to the Rutherford model necessary.
Furkat [3]
<span>Photoelectric effect refer to the emission of electron or free carriers when light shine into a material. According to the Rutherford model, light of any energy should be able to make electrons leave the atom and be emitted. The energy of the emitted electrons should be related to the intensity of the light. But the energy of the electron is actually only related to the energy of the light</span>

What is the similarity between teeth and eggshells?
topjm [15]

Explanation:

Because they share a similar composition, similar chemicals affect their structures in positive or negative ways. For example, fluoride – a staple in many dental practices – strengthens both enamel and eggshells and helps protect them from acids. Acids weaken and break down both substances. Scientists find this particularly concerning given that the ocean is growing increasingly acidic. They fear this may weaken the eggs of some marine species and harm their chance of survival. Most dentists recommend limiting aggressively acidic foods and beverages such as soft drinks.
