The words best describe the archer's results are The correct option is A.
<h3>What is accuracy?</h3>
When in an experiment, a value is measured 5 times, then if the values measured are same for most of the time or like three times out of five, it said to be accurate. The phenomenon is accuracy.
Precision is about comparing the values to each other then find them near to each other.
Given is an archer's targets on the target board.
Accuracy compares the experimental value to the theoretical value (desired target)
So, when all the values are close to each other but not nearest to the theoretical value, then it is said to be precise but not accurate.
Thus, the correct option is A.

Answer:
Angle of reflection = 30°
Explanation:
One of the laws of reflection is that the angle of incidence is equal to the angle of reflection.
The angle at which the light strikes the mirror is called the angle of incidence while the angle at which the light gets reflected back is called angle of reflection.
In this case, the angle of incidence is 30 degrees. So, we can say that the angle of reflection is also equal to 30 degrees.
Answer:
Electric charge, Q = 55.69 C
Explanation:
It is given that,
Electric current drawn by the compressor, I = 23.7 A
Time taken, t = 2.35 s
We need to find the electric charge passes through the circuit during this period. The definition of electric current is given by total charge divided by total time taken.
Where,
q is the electric charge
q = 55.69 C
So, the electric charge passes through the circuit during this period is 55.69 C. Hence, this is the required solution.
Answer: A difference in properties between two interacting systems as explained below.
Explanation: Planetary differentiation is the process of separation of different parts of a planetary body as a result of their physical or chemical behavior.
Causes for Physical Differentiation:
1. Melting and crystallization of source rock.
2. Differences in densities
3. Thermal diffusion
4. Collision of large bodies
Chemical Differentiation accounts for differences in chemical compositions of different materials.
The differentiation, or organization, of the Earth into layers led to the formation of a core, a crust, and eventually continents. The light elements were driven from the interior to form an ocean and atmosphere.
