If a computer chip switches off -on-off in 0.015 us, what is the switching time in nanoseconds?

-  15 nano seconds.

Solution:- It is a unit conversion problem where we are asked to convert to nano seconds, where stands for micro seconds.

We will convert micro seconds to seconds and then seconds to nanon seconds.

The conversion factors required here are:

]

and,

The set up is made as:

= 15 ns

So, the answer is 15 nano seconds.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
