The direction that an induced current flows in a circuit is given by

Physics
1 answer:
AURORKA [14]3 years ago
8 0

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.

Canola oil is less dense than water, so it floats on water, but its index of refraction is 1.47, higher than that of water. When
kupik [55]

Answer:

therefore critical angle c= 69.79°

Explanation:

Canola oil is less dense than water, so it floats over water.

Given n_{canola}= 1.47

which is higher than that of water

refractive index of water n_{water}=1.33

to calculate critical angle of light going from the oil into water

we know that

sinc= \frac{n_{water}}{n_{canola}}

now putting values we get

sinc= \frac{1.33}{1.47}

c= sin^{-1}(\frac{1.33}{1.47} )

c=69.79°

therefore critical angle c= 69.79°

An object is at rest. There are several forces acting on the object, but the net force is zero. If all the
pantera1 [17]
It would not. Imagine four forces equal in magnitude but opposite in direction (e.g. north, east, south, and west). If these forces were to double in magnitude they would still have the same magnitude, meaning the net force is still equal to zero.

14. A rocket is shot up into the air and then comes back down and hits the ground 9.2 second later.
sineoko [7]

Answer:

105.8 m

46 m/s

Explanation:

From the time the rocket is launched to the time it reaches its maximum height:

v = 0 m/s

a = -10 m/s²

t = 9.2 s / 2 = 4.6 s

Find: Δy and v₀

Δy = vt − ½ at²

Δy = (0 m/s) (4.6 s) − ½ (-10 m/s²) (4.6 s)²

Δy = 105.8 m

v = at + v₀

0 m/s = (-10 m/s²) (4.6 s) + v₀

v₀ = 46 m/s
