Answer:
The true statement is:
d. It is impossible to know which contains more energy.
Explanation:
In this scenario, the frequencies of Photon A and Photon B were not given. This makes it impossible to know which photon contains more energy than the other. Note that the amount of energy is directly proportional to the photon's electromagnetic frequency but inversely proportional to the wavelength. A description of the associated wavelengths was offered, but this description is not enough to help determine the energy of each photon. In conclusion, the photon's frequency determines its energy level just as the wavelength reduces its energy.
The quantity of natural resources in Africa led European nations to colonize Africa.
Answer: Option 3
<u>Explanation:</u>
Africa is well known for its natural resources. African countries’ soil was rich in minerals. Also, some of the African Countries are abundant with Oil resources.
The Europeans Colonized Africa as they can trade that wide variety of mineral resources and all the organic products. That includes Diamonds to rocks that contained uranium, zinc, tungsten, etc.. Also, tea, coffee, sugar, and tobacco were 90% percent of the exports from Africa.
Answer:
5480 mph
Explanation:
cuz trains went 160mph then if u add that up its correct
I would say it is. The one that says it transports nutrients and waste in the body
