if i am correct the answer is d. because depending on how far a wavelength goes we see different colors.
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.
Answer:
To your left
Explanation:
The direction of the force exerted on charged particle due to a magnetic field is given by the right-hand-rule, where:
- The index finger indicates the direction of motion of the electron
- the middle finger gives the direction of the magnetic field
- the thumb gives the direction of the force if the particle is positively charged - otherwise, the direction is reversed
in this case, we have an electron (so, a negatively charged particle):
- The direction of motion (index finger) is horizontal, toward you
- The electron begins to curve upward as it enters the field, so this means that the force exerted on the electrons is upward --> the thumb must point downward (because the electron is negatively charged)
- The index finger gives us the direction of the magnetic field: therefore, to your left.
There may be an improper voltage in the device.
<u>Explanation</u>:
- Given the device has unknown circuitry and the voltage across the device crosses the voltage across the resistor at 500 Hz. In this device, the current flow is not correct. It is improper.
- The elements in the device are ammeter, capacitor, inductor, voltmeter, and battery. The components in the device may not be connected properly. This is due to the improper flow of current and condition of the voltmeter.
- So these are the type of elements in the device.
