In LCR circuit, explain the terms; (1) characteristic impedance.
(2) Reactances. At what point does the circuit resonate? Give an expression for resonant froquency.​

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
