In a photoelectric experiment, a metal is irradiated with light of energy 3.56 eV. If a stopping potential of 1.10 V is required, what is the work function of the metal?

The  work function is  

Explanation:

From the question we are told that

    The light energy is  

     The  stopping voltage is  

Generally work function is mathematically represented as

Where KE is the kinetic energy of the ejected electron and it is mathematically represented as

Where  e is the charge on the electron

So  

Thus  

=>      

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

i guess it’s a and b
