Answer:
The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow.

Answer:
d = 23.75 m
The zebra has gone 23.75m after 5 seconds.
Corrected question;
A zebra starts from rest and accelerates at 1.9 m/s2. How far has the zebra gone after 5 seconds.
Explanation:
From the equation of motion;
d = vt + 0.5at^2 .........1
Where;
d = displacement
v = initial velocity = 0
t = time taken= 5 seconds
a = acceleration = 1.9 m/s^2
Substituting the given values into equation 1;
d = 0(5) + 0.5(1.9×5^2)
d = 0.5(1.9×5^2)
d = 23.75 m
The zebra has gone 23.75m after 5 seconds.
Answer:
Δx = 2m
Explanation:
From the given information:
De la información dada:
El desplazamiento ocurrió en un vector que se mueve desde una posición inicial particular hasta el final.
Entonces, supongamos que el desplazamiento es D;
Luego:
D = (7,5 ) - (5,7)
D = (2, -2)
Por lo tanto, el valor del desplazamiento de la coordenada x; Δx = 2m
