How is the stability of a nucleus affected by changing the number of nuclear particles?
Svet_ta [14]

Answer:

Greatly affected.

Explanation:

The stability of a nucleus is greatly affected by changing the number of nuclear particles because changing the number of nuclear particles i.e. neutron or proton will leads to change the element. When we change the number of protons in an atom, we will change the atom from one element to a different element. Sometimes, when you add a proton to an element, the element will become radioactive in nature so we can conclude that changing number of nuclear particles impact the stability of nucleus of an atom.

A sample obtained from the national bureau of standards had a calibrated weight of 20.000. When it was used tocalibrate a studen
melisa1 [442]

Answer : The measurements are both precise and accurate.

Explanation :

Accuracy : It is defined as the closeness of a measured value to a standard or known value.

For Example: If the mass of a substance is 50 kg and one person weighed 48 kg and another person weighed 55 kg. Then, the weight measured by first person is more accurate.

Precision : It is defined as the closeness of two or more measurements to each other.

For Example: If you weigh a given substance five times and you get 1.8 kg each time. Then the measurement is said to be precise.

Level of precision is determined by the maximum number of decimal places.

When the level of precision is very very less, the measurement can be considered as most precise and most accurate.

As we are given the standard value of the sample is 20.000 and the values measured by the balance are, 19.995, 20.005, 20.001.

Since these three values are in the range of +/- 0.005 from one another. So, we can say that the measurements are both precise and accurate.

Hence, the measurements are both precise and accurate.
