The change in the gravitational potential energy is represented by the equation
u = ΔPE = Δmgh
since the mass of the system will remain constant and the acceleration due to gravity will also remain constant, the equation will become
u = mg Δh
Answer:
3.5434 eV
Explanation:
For a particle with kinetic energy E and mass m , the wavelength associated is given by the following relation,
E = 
Putting the values we get
E = 
=1.063 x 10⁻²¹ J
= .0066 eV.
Energy of¹light in terms of eV
= 1244 / 350 = 3.55 eV.
Work function = 3.55 - 0.0066 = 3.5434 eV.
Characteristic properties of a given substance is different from its other properties is that there is no change as to what it is no matter how big or how small the sample of the given substance is. Another thing is that it doesn't affect the chemical nature of the matter. The characteristic properties of a given substance can either be a physical property of the substance or a chemical property of the substance. Either way, there is no change to it even if the size of the substance changes.
The rate at which velocity changes over time is <em>acceleration</em>.
