voltage = current * resistance
so
current = voltage/resistance
therefore,
current = 6/3 A = 2 A
Dispersion
Explanation:
The best word that describes the phenomenon that gives rise to rainbow is dispersion of light.
Dispersion is the process by which white light is separated into different colors or radiation according to their different wavelength.
- In the atmosphere, rainbow is an arc of different colors that forms in the sky.
- Rainbow forms when light is dispersed by water in the atmosphere.
- When rainbow forms light is separated into its different colors and it can be seen in the sky.

<h2>
Answer: 450 Bq</h2>
Explanation:
This problem can be solved using the Radioactive Half Life Formula:
(1)
Where:
is the final amount of radioisotope (decay rate)
is the initial amount of the radioisotope
is the time elapsed
is the half life of the radioisotope
Knowing this, let's find from (1):
(2)
(3)
Finally:
>>> This is the decay rate of the radioisotope
Note it is in Becquerels (Bq), which is the derived unit approved by the <u>International System of Units</u> for radioactivity
