Answer: Electron Cloud Model
Explanation:
The electron cloud model says that we cannot know exactly where an electron is at any given time, but the electrons are more likely to be in specific areas. These areas are specified by orbitals. The orbitals are specified by shells and sub-orbitals. In the Bohr model, electrons are assigned to different shells.
Terabytes. 1 terabyte is equal to 1,000 gigabytes
Answer: D
Explanation: Look at the figure, we can conclude that the correct answer is
X: Low potential energy
Y: High potential energy
Z: Flow of electrons
Because electrons flow where there is difference in potential energy. And electrons move from a region of high potential energy to a region of low potential energy.
Since the arrow is pointing to X, that means
Z is the flow of electrons, X is of low potential energy and Y is of high potential energy.
consider the west direction as positive direction of motion
V' = velocity of airplane relative to observer on ground = 580 mph
v = velocity of wind relative to observer on ground
V = average speed of airplane with no wind = 600 mph
relative velocity is given as
V' = V + v
inserting the values
580 = 600 + v
v = 580 - 600
v = - 20 mph
the negative sign indicates the direction of wind is opposite to direction of airplane , east
hence speed of wind is 20 mph in east direction.
