Answer:
Lenz's law
Explanation:
it states that induced emf of different polarities induces a current whose magnetic field opposes the change in magnetic flux through the coil in order to ensure that original flux is maintained through the coil when current flows in it.
according to Faraday' s law of electromagnetic induction
Where -ve sign due to lenz's law
Emf is the induced voltage also known as electromotive force
N is the number of loops.
dϕ Change in magnetic flux.
dt Change in time.
centimeter or millimeter.
Explanation:
The unit of length most suitable for measuring the thickness of a cell phone is centimeter or millimeter.
Length refers to how long a material is.
- There are different units of length.
- Smaller units that are microscopic are used to measure length dimensions that are very small
- For example, nanometre is used to express microscopic length values.
- Centimeters and millimeters are used for small dimensions that we can easily see.
- Longer lengths can take the order of a yard, kilometer, miles e.t.c

Technically? It's not wrong. A star is a ball of gas that is held together by it's own gravity of which it constantly struggles against. Gravity constantly works to try and make the star collapse. However, stars are extremely hot at their cores which help the star push against it's own gravity creating a sort of equilibrium. So long as the star continues to push against gravity, it will not collapse, however eventually a star will lose its energy and eventually collapse into a black hole.
Answer:
t = 12.8 s
Explanation:
As we know that the deepest point of the canyon is 800 m
so here we will have the displacement of the rock in the canyon is same as that of depth of the canyon
So here we will say
now we have
