Answer:
led would be the best for decorations
Explanation:
A. To find work we need to know F and S; to find power we need to know F and V
Answer:
Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A
Explanation:
Let the depth of each section is h.
That means the real depth for each section is h.
Apparent depth is liquid A is 7 cm.
Apparent depth in liquid B is 6 cm.
Apparent depth in liquid C is 5 cm.
by the formula of the refractive index
n = real depth / apparent depth
where, n is the refractive index of the liquid.
For liquid A:
.... (1)
For liquid B:
..... (2)
For liquid C:
..... (3)
By comparing all the three equations
nc > nB > nA
Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A
The energy stored in a capacitor is given by

where C is the value of the capacitance while V is the voltage difference applied to the capacitor.
Let's calculate the energy of the first capacitor:

And now the energy of the second capacitor:

So, the total energy stored in the two capacitors is
