A:
The white light is divided into its component hues - red, orange, yellow, green, blue, and violet - as it passes through the prism. Dispersion is the splitting of visible light into its many hues.

B:
Dispersion is the splitting of visible light into its many hues. Each hue is associated with a certain wave frequency, as stated in the Light and Color unit, and different frequencies of light waves bend at different rates while passing through a prism.

D:
The sun and the weather combine to create a rainbow. As it passes from air to denser water, light enters a water droplet, slowing and bending. The light bounces off the interior of the droplet, separating the wavelengths—or colors—that make up the droplet. A rainbow is created as light escapes the droplet.
The statement that is true is that positively charged objects attract negatively charged objects. This is due to a law that states 'like forces attract while unlike forces repel. This same concept applies to magnetism. If you put two similar poles together, for example; if you place two south poles together. You feel a separating force between the two poles. But if you place two opposite poles together they attract each other. Hope i helped. <span />
Answer:
Length/time
Explanation:
As in the definition...Velocity is the rate of change of displacement...so hence
Velocity = Displacement/Time...where Displacement is length
Velocity = Length/Time
Answer:
1) The girl's acceleration at time 't' is,
m/s²
2) The girl's acceleration at time 't₁' is,
m/s²
3) The girl's acceleration at time 't₂' is,
m/s²
Explanation:
Given data,
The initial walking speed of the girl, u = 0
The speed of the girl at the time 't' 3 s is, v₁ = 1.4 m/s
The time period the girl walked at the speed 1.4 m/s is, t₁ = 6 s
The girl slows down and comes to a stop during a period, t₂ = 10 s
1) The girl's acceleration at time 't'


m/s²
2) The girl's acceleration at time 't₁'


m/s²
3) The girl's acceleration at time 't₂'


m/s²
