Answer 1

Answer:

Explanation:-

PART 1:-

Hypermetropia, sometimes called hyperopia, is the term used to define being longsighted. If you are hypermetropic, the image of a nearby object is formed behind the retina. This means that light is focused too far back in the eye, causing things which are close up to appear blurred.

PART 2 :-

Equivalent resistance of two coils =3ohms + 6 ohms = 9 ohms

By ohms law V=IR,

12=I*9

I=12/9

I=4/3 A

We know ,

E = I*V*t

E = 4/3 * 12 * 60

E = 960 J
