Answer:
If white light shines on a red ball, the ball reflects back mostly red light, and so we see red. Most of the greens and blues that are part of white light are absorbed by the ball so we cannot see them. Likewise, a blue book is reflecting the blue part of the white light spectrum.
Answer:
166.8 m
30.18 m/s
Explanation:
u = Velocidad inicial del automóvil = 120 km/h =
v = Velocidad final = 0
s = Desplazamiento
a = Aceleración
t = Tiempo tomado = 10 s
De las ecuaciones cinemáticas de movimiento tenemos
La distancia que tarda el automóvil en detenerse es 166.8 m
Ahora s = 30 m
La velocidad a la que el otro automóvil sería golpeado es 30.18 m/s.
convergent and counterclockwise
hope it helps :)
Answer:
Below in bold.
Explanation:
Newton's Second Law:
Force = mass * acceleration
So
Force = 24.5 * 2.3
= 56.35 Newtons.
