Milli means 1 thousandth or 1/1000
Answer:
D) Image cannot be seen
Explanation:
As we know by lens formula
now we know that
object is placed at the focal point of lens
so we will have
so the image will form at infinite
so image will be at infinite distance from the lens
so it cannot be seen
Answer:
A.) Most nonmetals are gaseous, but some are liquid or solid
Explanation:
is the equation that represents the Joule's law of heating.
<h3>
Explanation:</h3>
Joule's law of heating defines the heat generated by any current flowing conductor is directly proportional to
1. Square of Current (I²),
2. Resistance of the conductor (R)
3. Time for which current is passed (t)
Hence, Heat generated = .....................(1)
By Ohm's Law, the potential difference (V) across a conductor is directly proportional to the current(I) flowing through it. The constant of proportionality is termed as resistance of the conductor (R).
...............................................(2)
From (2), Current (I) can be rewritten as
........................................................(3)
Substituting (3) in (1), we get
I haven’t learned this in quite a while, but from what I remember it should be A! I could be wrong but hopefully this helps
