Answer:

We don't get shocked because of the type of materials used in the switch is a poor conductor of electricity

Explanation:

Yes it is quite amazing we don't get shocked, this is because of resistance of the type of materials used in the switch (non conductors of electricity) so that when you try to put on a switch no current passes through you, mostly the material are made from plastics Or ceramics which are actually poor conductors of electricity.

liberstina [14]

Explanation:

Given: \lambda = 500\:\text{nm} = 5×10^{-7}\:\text{m}

\nu = \dfrac{c}{\lambda} = \dfrac{3×10^8\:\text{m/s}}{5×10^{-7}\:\text{m}}

\:\:\:\:\:= 6×10^{14}\:\text{Hz}

The work function \phi is then

\phi = h\nu = (6.626×10^{-34}\:\text{J-s})(6×10^{14}\:\text{Hz})

\:\:\:\:\:\:\:= 3.98×10^{-19}\:\text{J}

what is the closest to the order of magnitude of the energy rquired to split a nucleus in to its individual protons and neutrons
skad [1K]

Answer:

More than two million electron volts.

Explanation:

More than two million electron volts energy are needed to break or split a deuteron into a proton and a neutron. Nuclear binding energy is the type of energy that is required to split an atom's nucleus into protons and neutrons. The deuteron is an isotope of hydrogen that is composed of a proton and a neutron and it is a stable particle. Very huge amount of energy is needed for the splitting of nucleus due to the presence of heavy particles i.e. proton and neutron.
