The speed of light inside a medium is (2.0 x 10^8m/s) What is the index of refraction (n) of the medium?

Physics
1 answer:
kondor19780726 [428]2 years ago

Answer:

Refractive index of a medium = Speed of light in vacuum/Speed of light in a medium

1.5 = 3 x 108 / Speed of light in medium

Speed of light in the medium = 3 x 108 /1.5

= 2 x 108 m/s.

Alice kicks a 0.25 kg soccer ball with 0.5 N of force. What force does the ball exert on Alice’s foot as she kicks it
Lelechka [254]
You do not doubt it. The third Law of Newton really works. I would say it is the most reliable law of the Universe. Action and reaction. It is not subject to special conditions, it works always. If an object exerts a force over other object, the second object exerts a force of equal magnitude but in the opposed direction over the first.

So, the answer, undoubtedly, is that the ball exerts a force of 0.5 N over Alices's foot as she kicks it.

*URGENT* Why is understanding motion so important? Be sure to explain in your own words.
levacccp [35]

Answer:

Motion is one of the important issues of Physics. We know that if we are not moving but still earth is moving. Motion is a bit of the machinist's Department of Physics. Several laws are provided for explaining the theory of motion and evolution in motion. The motion and transformation are defined in terms of strength which is wanted for creating an object in a motion state.

A soccer ball is kicked from the ground with an initial speed of 20.1 m/s at an upward angle of 47.8˚. A player 53.0 m away in t
e-lub [12.9K]

Answer:3.95 m/s

Explanation:

Given

Initial velocity(u)=20.1 m/s

launch angle=47.8^{\circ}

Player is 53 m away

Range of projectile

R=\frac{u^2sin2\theta }{g}

R=\frac{20.1^2\times sin95.6}{9.8}

R=41.02 m

so he need to run 53-41.02=11.98 m

Time of flight of projectile =\frac{2usin\theta }{g}

T=3.03 s

thus average speed of boy s_{avg}=\frac{11.98}{3.03}=3.95 m/s

¿Una corriente eléctrica sin resistencia puede fluir constantemente sin fuente alguna de potencia? Explique.
frosja888 [35]

Answer:

No.

Explicación:

No, una corriente eléctrica sin resistencia no puede fluir constantemente sin ninguna fuente de energía porque la fuente de energía proporciona electrones para el flujo continuo de corriente en el circuito. Si fluye corriente por el cable, debe haber resistencia en el circuito. La fuente de energía proporciona corriente eléctrica continua al cable para que fluya y el cable tiene resistencia, por lo que parte de la corriente eléctrica se pierde durante su flujo debido a esta resistencia. Entonces podemos decir que la fuente de energía es necesaria para el flujo constante de corriente eléctrica.

When the nanocrystalline semiconductor samples provided in case study are irradiated with violet light, you should observe that
romanna [79]

Answer:

Due to the different lattice arrangement of nanocrystalline semiconductors, they will be able to emit different colors of light.

Explanation:

An essential feature in nanocrystalline semiconductor samples is that they may not have the same or in some cases similar structures. This characteristic is due to the fact that nanocrystals do not grow equally, presenting different shapes. Nanocrystals with uneven shapes may absorb light of a certain wavelength, but due to their uneven characteristics, the light emitted may be of a different wavelength.
