f is the force
m is the mass
From the question we have

We have the final answer as
<h3>7 m/s²</h3>
Hope this helps you
The mass of a is smaller than the mass of b.
Answer:
because of tungsten's high melting point
Explanation:
This is because, nuclear forces are short range forces.
The protons and neutrons are collectively called nucleons and they are found in the nucleus of an atom. These nucleons are held together by a strong attractive force called the nuclear force.
When atoms combine, they are held together by forces determined by electrons in the outermost shell. The influence of the nuclear force does not extend beyond the nucleus because they are short range forces.
Hence, we not consider the strong nuclear force when we describe the forces between atoms.

Explanation:
-Uncertainty refers to an estimate of the amount by which a result may differ from this value,
-Precision refers to how closely repeated measurements agree with each other.
-Accuracy refers to how closely a measured value agrees with the correct value.
-The number of significant figures is the number of digits believed to be correct by the person doing the measuring. Therefore, choosing the correct number of significant figures reduces the deviation from the point of accuracy/uncertainty or precision and thereby reducing margin of error in the ensuing calculations.
