The water has a higher viscosity and surface tension compared to the methanol.
<h3>What is Surface Tension?</h3>
Surface tension can be defined as the force that acts on the surface of a liquid to give it am elastic skin that is stretched.
Thus, because of the strong intermolecular hydrogen bonding in water and it's high melting and boiling point than methanol, the surface tension and viscosity of water is higher than that of methanol.

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals.
<h3>How to find the stress experimented by the bungee cord</h3>
Let suppose that the stress (
), in pascals, experimented by the bungee cord is entirely <em>elastic </em>and <em>uniform</em>. By Newton's Laws we know that the tension (
), in newtons, experimented by the cord equals Max's weight. The stress on the bungee cord is axial and is described by following formula:
(1)
Where:
- Max's mass, in kilograms
- Gravitational acceleration, in meters per square second
- Diameter of the circular cross section, in meters
If we know that
,
and
, then the stress experimented by the bungee cord is:


The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals.
