Light is consist of different spectrum of colors called wave lengths. The colors that visible to the naked eye are known as Red, Orange, Yellow, Green, Blue, Indigo, and Violet. These colors are arranged from shortest to longest. The color red that appeared from the other side of the tank signifies that the wavelength that can only pass through the material is red, which is the shortest. Other wavelengths are dispersed into the molecules of the glass, hence it cannot be seen through the other side.
Answer:
Explanation:
Length, l = 4.32 x 10^4 m
speed, v = 7.07 x 10^3 m/s
magnetic field, B = 5.81 x 10^-5 T
The formula for the motion emf is given by
e = B x v x l
e = 5.81 x 10^-5 x 7.07 x 10^3 x 4.32 x 10^4
e = 17745.1 V
Answer:
Group IA elements have only one valency electron while Group IIA have two valency electrons.
Group IA elements have cations with higher charge density hence polarizing anions easier resulting into covalent character while Group IIA elements have cations with lower charge density hence difficulty in distorting anions resulting into a ionic character. This is due to difference in cationic radii and charges
The questions from this lot which could be tested in a scientific manner would be "what causes some people to be color-blind"
and
"what are the best shoes to wear when exercising"
Both of these questions can be tested in a scientific way through an experiment.
