Answer:
acceleration=(v final-vinitial)/time
a=(vf-vi)/t
2=(30-10)/t
2=20/t
t=20/2=10 seconds
distance=v0t+at²/2
d=10 x 10+ 2x 10²/2=100+100= 200 m

Answer:
In chemistry and physics, a valence electron is an outer shell electron with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Explanation:
The true statement about the accuracy and precision of measuring tools is Tools cannot be both accurate and precise. The correct option is C.
<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.
Accuracy compares the experimental value to the theoretical value.
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 C.
