C) alternately increase and decrease
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.

Answer:
The trouble that the most recent experiment, Borexino, have to overcome was that
neutrinos hardly interact with matter and so radioactive decay of ant material inside the detector could look exactly like a neutrino interaction too
The statement (C) <span>The current carrying loop is able to turn because the magnetic force is always parallel to it.
In an electric motor the current do not reduce at any point. So, the (A) is also not correct.
The correct statement about an electric motor is (B),
</span><span>The current carrying loop is able to turn because the magnetic force is always at a right angle to it.</span>
