Answer:
option b is correct option = (6.76×10¹⁴ Hz)
Explanation:
Given data:
Wavelength of photon = 4.42×10⁻⁷ m
Speed of light = 2.99×10⁸ m/s
Frequency of radiation = ?
Solution:
Formula:
Speed of wave = frequency × wavelength
Now we will rearrange this formula.
frequency = Speed of wave / wavelength
f = c/ λ
f = 2.99×10⁸ m/s / 4.42×10⁻⁷ m
f = 0.676×10¹⁵ Hz (s⁻¹ = Hz)
f = 6.76×10¹⁴ Hz
Thus option b is correct option.
Answer:
minerals of volcanic origin with large crystals is formed by magma that cooled off deeper into the crust.
Explanation:
the rocks of volcanic origin are divided into two main categories by the place of formation. extrusive igneous rocks and intrusive igneous rocks .extrusive igneous rocks are the one that are formed on the surface .the intrusive igneous rocks are formed deeper into the crust
Purebreds
Purebreds are the result of true breeding where specimens breed true-to type when mated like-to-like. The idea is that the purebred has fundamental characteristics that are consistent, replicable and predictable. Pure breeding is of necessity carried out from a restricted gene pool which has been a cause for concern. As the positive characteristics of any species or type are perpetuated through true breeding so are the undesirable traits which are a result of inbreeding. The limited gene pool leaves purebred products susceptible to a range of congenital health issues particularly where the emphasis is on aesthetics.
Hybrids
A hybrid organism is one with parentage of two different species. In the animal kingdom, mules (horse and donkey), ligers (tiger and lion), yakalos (yak and buffalo) and so on are familiar hybrids. There are various types of hybrids possible. The most obvious kind is offspring resulting from the interbreeding of two species. The second kind is hybrids between different subspecies which include intra-specific (between subspecies), intergeneric (between genera) and interfamilial hybrids. The third sort of hybrid is that caused by selective breeding to enhance and make consistent desirable characteristics such as heat tolerance amongst certain breeds of cattle.
Answer:
The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.
CO2. An ionic compound is a metal and a nonmetal.
