Answer:
A los 10 segundos su velocidad será 15
Explanation:
La aceleración de un objeto es una magnitud que indica cómo cambia la velocidad del objeto en una unidad de tiempo.
En otras palabras, la aceleración relaciona los cambios de la velocidad con el tiempo en el que se producen, es decir que mide cómo de rápidos son los cambios de velocidad:
- Una aceleración grande significa que la velocidad cambia rápidamente.
- Una aceleración pequeña significa que la velocidad cambia lentamente.
- Una aceleración cero significa que la velocidad no cambia.
La aceleración "a" puede ser calculada mediante la expresión:
En este caso:
- a= 1
- vfinal= ?
- vinicial= 5
- tiempo= 10 s
Reemplazando:
Resolviendo se obtiene:
1 *10 s= vfinal - 5
10 = vfinal - 5
10 + 5
= vfinal
15 = vfinal
<u><em>A los 10 segundos su velocidad será 15 </em></u><u><em></em></u>
Mainly because of the higher energy of blue light than red light.
In fact, light is made of photons, each one carrying an energy equal to
where h is the Planck constant while f is the frequency of the light.
The frequency of red light is approximately 450 THz, while the frequency of blue light is about 650 Hz. Higher frequency means higher energy, so blue light is more energetic than red light and therefore it can cause more damages than red light.
