Answer: Descubrio una forma de observar la corriente estática, y quizas fue uno de los primeros en observarla y escribir sobre ella.

Explanation:

Alrededor del 600 a.C. Tales se da cuenta de que frotando pieles con otros materiales, lograba que estos atrajeran motas de polvo, y luego escribió sobre esto que hoy en día conocemos como electricidad estática. De hecho los romanos descubrieron que frotando pieles con ámbar podían ver como pequeñas chispas saltando de estos.

Esto sucede por que al frotar los dos materiales, uno de ellos tiene tendencia a perder cargas mientras el otro (usualmente conductor o aislante) tendrá tendencia a absorberlos. Luego esas cargas absorbidas son una corriente estática que queda "almacenada" en uno de los materiales.

Entonces podemos decir que el aporte a la electrostática que se le atribuye a Tales de Mileto es "descubrir" la electricidad estática.

A 60kg student traveling in a 1000kg car with a constant velocity has a kinetic energy of 1.2 x 10^4 J. What is the speedometer
777dan777 [17]

Answer:

17.64 km/h

Explanation:

mass of car, m = 1000 kg

Kinetic energy of car, K = 1.2 x 10^4 J

Let the speed of car is v.

Use the formula for kinetic energy.

K = \frac{1}{2}mv^{2}

By substituting the values

1.2\times 10^{4} = \frac{1}{2}\times 1000\times v^{2}

v = 4.9 m/s

Now convert metre per second into km / h

We know that

1 km = 1000 m

1 h = 3600 second

So, v = \left (\frac{4.9}{1000}   \right )\times \left ( \frac{3600}{1} \right )

v = 17.64 km/h

Thus, the reading of speedometer is 17.64 km/h.

Light of wavelength 500 nm is incident perpendicularly from air on a film 10-4cm thick and of refractive index 1.375. Part of th
Marysya12 [62]

Answer

given,

wavelength (λ)= 500 n m

thickness of film= 10⁻⁴ cm

refractive index = μ = 1.375

distance traveled is double which is equal to 2 x 10⁻⁴ cm

a) Number of wave

     N = \dfrac{d}{\mu\lambda}

     N = \dfrac{2 \times 10^{-6}}{1.375\times 500 \times 10^{-9}}

           N = 2.91

           N = 3

b) phase difference is equal to

Reflection from the first surface has a 180° (½λ) phase change.

There is no phase change for the 2nd surface reflection and there is no phase difference for the 2nd wave having traveled an exact whole number of waves.

net phase difference = 180^0\times \dfrac{3}{2}

                                   = 270°
