Un haz de luz en el aire incide sobre la superficie de una placa de cuarzo fundido (n=1.46). Parte del haz entra al cuarzo, con un ángulo de refracción de 30° y otra parte se refleja ¿cuál es el ángulo de reflexión?. Solo escribe el numero, sin el símbolo de grado.

3x + 2x = both people using the same measure of like 5x = x= 25 meters per second. 25ms. it takes them 4 seconds to

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
