A positive charge of 1 µC is taken from points A &amp; B such that VA-VB = 100 V. Then the
Lunna [17]

Explanation:

It is given that,

Let Charge of 1\ \mu C is taken from points A & B such that V_A-V_B=1000\ V.

We need to find the energy of charge. Electric potential is defined as the work done per unit of electric charge. So,

W=(V_B-V_A)q\\\\W=-1000\times 10^{-6}\\\\W=E=-10^{-3}\ J

So, the energy of charge decreases by 10^{-3}\ J. Hence, the correct option  is (a).

Electrons are emitted from a surface when light of wavelength 500 nm is shone on the surface but electrons are not emitted for l
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}

How are hot spots used to track plate motion
DanielleElmas [232]
When plates move they sometimes open small cracks that release heat from under earths plate, coming from the mantle or even the core at times, this heat allows scientists to determine where the plates are moving from and where they are moving to.
