Explanation:
Given
Area of heel 
Mass of woman 
Pressure is defined as Force applied in over an area such that it is perpendicular to it i.e.






Explanation:
We need to find the speed of a 3.1eV proton and a 3.1eV electron.
For proton, using conservation of energy such that,

is mass of proton

For electron,

is mass of proton

Hence, this is the required solution.
In the context of variables and measurement scales, the magnitude of the differences between the numbers on the scale is meaningful interval scale.
<h3>What is an interval scale?</h3>
It should be noted that an interval scale means a measurement where the difference between the variables is meaningful and equal.
In this case, in the context of variables and measurement scales, the magnitude of the differences between the numbers on the scale is meaningful interval scale.
