Hope it helps!
Explanation:
Light behaves both as a particle and as a wave. When UV light hits a metal surface, it causes an emission of electrons. Albert Einstein explained this "photoelectric" effect by proposing that light – thought to only be a wave – is also a stream of particles.
The main point of Einstein's light quantum theory is that light's energy is related to its oscillation frequency. ... The various properties of light, which is a type of electromagnetic wave, are due to the behavior of extremely small particles called photons that are invisible to the naked eye.

Answer:
The magnitude of the acceleration is equal to 19.6m/s² and the acceleration is directed upwards though the magnitude of the charge has doubled. This is because the electric force is directed upwards and from newton's second law of motion the charge will have acceleration in the same direction as the electric force on the charge.

The correct answer is the Black Market.
The Black Market refers to the informal (and sometimes formal) system of trading of illegal goods by merchants and dealers of products such a weapons, drugs, and good that have been banned by countries. This can also apply to informal marketplaces in countries with sanctions placed upon them get goods that formal treaties are blocking the people from accessing.
Answer:
La aceleración total de la piedra es 2,85 m/s².
Explanation:
La aceleracion total de la piedra viene dado por la suma de la acelaración centrípeta y de aceleración tangencial, como:
La aceleración tangencial () es la aceleracion del cilindro igua a:
Entonces, la aceleración centrípeta es:
En donde:
v: es la velocidad tangencial de la piedra = 2,0 m/s
r: es el radio del cilindro = 1,5 m
Finalmente, el módulo de la aceleración total es:
Por lo tanto la aceleración total de la piedra es 2,85 m/s².
