1.5, because I said so.
Explanation:
Alfred Wegener was a meteorologist and geologist. He was inspired by a map of continents to start the journey of explaining Earth's geological history. He gave the theory of continental drift which says that the continents of Earth have moved relative to each other over time. He used following evidences to support his theory:
1. The facing side of South America's and Africa's shoreline interlocks perfectly. Which implies they must have been joined together in history.
2. Fossil of same type of reptiles found on different continents separated by huge oceans.
3. Matching the rock pieces on either side of the Atlantic oceans.
Answer: The correct answer is: coastline fits between different continents, similar rocks and fossils on different continents
Explanation: I took the test
B) As the frequency of the wave fluctuates, its energy decreases.
C) As the frequency of the wave increases, its energy also increases.
D) As the frequency of the wave changes, its energy remains constant.
As the frequency of the wave increases, its energy also increases. The correct option is C.
The frequency of an electromagnetic wave is defined as the number of oscillations or cycles per unit of time.
The frequency of the wave, on the other hand, is directly proportional to energy.
The energy of an electromagneticwave is precisely proportional to its frequency, according to the equation E = hf, where E represents energy, h is Planck's constant, and f is the frequency of the wave.
Simply said, higher frequency waves have more energy than lower frequency waves.
This is true over the whole electromagneticspectrum, from radio waves to gamma rays. The energy carried by the wave rises as the frequency of the wave increases.
Thus, the correct option is C.

Answer: hydroxyl ion
Explanation:
When base is dissolved in water it dissociate and produce an hydroxyl ion
