Answer:

Explanation:
The current through the bulb, I = 0.75 A
We need to find the number of electrons flowing per second. We know that the electric current is given by :

So, there are
electrons flowing per second.
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
False
Nothing has the same destiny everything has their own destiny to follow
The answer is A because there’s so much heat in the core and pressure because of all of the layers of the earth
