Answer:
Explanation:
Plate separation, d = 1.76 cm = 0.0176 m
Area of plates, A = 25 cm^2 = 0.0025 m^2
V = 255 V
(a) Capacitance of capacitor
C = 1.258 x 10^-12 F
charge is same before and after immersion as the battery is disconnected
q = C V
q = 1.258 x 10^-12 x 255 = 3.2 x 10^-10 C
(b)
Capacitance before, C = 1.258 x 10^-12 C
capacitance after, C' = k x C = 80 x 1.258 x 10^-12 = 100.64 x 10^-12 C
Where, k is the dielectric constant of water = 80
Potential difference after immersion, V' = V / k = 255 / 80 = 3.1875 V
(c) initial energy,
Final energy
Answer:
Explanation:
First we calculate the energy of the photon
E=(Planck constant × speed of light in vacuum)÷ wave length
E=
Next we find the total energy per second
total energy= 
Next we calculate the number the photon per second
= total energy ÷ energy of 1 photon
= 
62 liters or 62.640 if you need decimal.
It would be B because they are just an explanation of what happens during a experiment
Answer:
A) a piece of wire
Explanation:
A simple fuse consists of a small piece of wire which has a high resistance and low melting point so that when a high current flows through it , it melts breaking the electric circuit and saving the electrical appliance from any danger.
