Answer:
The wave is traveling in the +x direction.
Explanation:
The equation of a wave is given by the formula as :
Here,
A is the amplitude of wave
is the phase of wave
is the angular frequency of the wave
We need to find the correct statement out of given options. The given equation can be rewritten as :
Here, the propagation constant is negative. So, the wave is moving in +x direction. Hence, the correct option is (a).
Answer: To form a cloud, the air that rises must cool to the point where some of the water vapor molecules "clump together" at a faster pace than they are pulled apart by their thermal energy. These molecules then condense to form the clouds and water droplets.
Heat it until it evaporates(Gas) :3
Or freeze it until its ice.(Solid)
its already a liquid normally
Unless you mean like separate the noodles from the broth, in that case use a drainer :'D Jk. I suck at smart stuff.
Answer:
B: The colors of light emitted from heated atoms had very specific energies.
Explanation:
In Thompson's model of an atom the atom is said to be constituted of electrons which are surrounded by a haze of positive charge in order to balance the electrons' negative charges. It is also called plum prodding model because of negatively charged plums which are surrounded by the positively charged pudding.
Now, as the electrons move from higher to lower energy levels a photon which is a particle of light will be given off.
Thus, the correct answer is option B
