Answer:
Accurate - Yes
Precise - Yes
Explanation:
Accuracy and precision are two ways to detect the closeness of measured values in an experiment. However, these two terms do not mean the same thing.
Accuracy of a measurement refers to how close a measurement (experimental values) is to a true or actual value while the precision of a measurement refers to how close the experimental or measured values are to one another.
Note that, a measurement may be accurate but not precise or be precise but not accurate.
In the case of the dart board in the image, it is evident that the measured values (represented by darts) are close to the middle target (represents the known or accepted mark). Hence, the measurements are said to be ACCURATE. Likewise, the measured values are also close to one another, meaning that they are PRECISE.
Therefore, the measurements are both precise and accurate.

Answer:
Explanation:
In an atom, there is a dense center known as the nucleus. It is made up of two subatomic particles: <u>protons</u> and <u>neutrons</u>. The protons have a positive charge and the neutrons have no charge, so overall the nucleus is positively charged.
The third subatomic particles, negatively charged electrons, are located around the nucleus in a cloud.
The particles in the nucleus are 
.
