Answer:
1. Hydrogen
Explanation:
These planets contain liquid hydrogen in their interior, while the earth has liquid iron in it.
When liquid hydrogen is in tremendous pressure enviroments, the electrons that make up each atom of this element end up "jumping" to other atoms. These "jumps" allow liquid hydrogen to behave like a metal.
In addition, with the constant energy released by the nucleus of planets like Jupiter and Saturn, as well as their rotations, the liquid hydrogen receives induction of currents, giving rise to extremely powerful magnetic fields.
Answer:
5.5 × 10^14 Hz
Explanation:
The wavelength can be represented using the formula;
λ = v/f
Where;
λ = wavelength (m)
v = speed of light (3 × 10^8m/s)
f = frequency (Hz)
According to this question, a light associated with the visible spectrum has a wavelength of 550 nm.
550nm = 550 × 10^-9m
f = v/λ
f = 3 × 10^8 ÷ 550 × 10^-9
f = 0.0055 × 10^ (8+9)
f = 0.0055 × 10^17
f = 5.5 × 10^14 Hz
The frequency is 5.5 × 10^14 Hz
There are several elements in the Periodic Table that are both malleable and good conductors of electricity and even heat. The Alkali metals such as potassium and sodium from Group 1 of the Periodic Table are very good conductors of electricity and are also pliant and malleable. From the group of Transition metals iron, copper, silver and gold are instances of all the 38 metals of this group that fulfil the conditions of being conductors and malleable. Some metals such as tin, lead, thallium, and aluminium are instances of elements that are malleable and can conduct electricity in the solid form. These elements belong to the Metalloids group in the Periodic Table.
