Answer:
When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.
Answer:
Testable
Explanation:
A good hypothesis must always be testable.
Answer;
-A wave with the longest wavelength.
Explanation;
-Diffraction is the apparent of wave through,around small obstacles and the spreading out of wave past small openings. When thinking of diffraction of a wave think of shining a flashlight around a corner. The light bends around the corner but there is a place where it is dark and the light does not hit. Diffraction of a wave is basically the wave bending around an object then dispersing out.
-The amount of diffraction (the sharpness of the bending) increases with increasing wavelength and decreases with decreasing wavelength. When the wavelength of the waves is smaller than the obstacle, no noticeable diffraction occurs.
Question:
How do mountain glaciers and continental glaciers differ in terms of dimensions, thickness and patterns of movement?
Answer:
<span>
Continental glaciers are thicker, much more expansive sheets. Mountain glaciers flow downhill as a result of gravity acting on the mass of ice. Continental glaciers move in response to pressure from the weight of material in their thick midsections.

Answer:
The 
electrons are moving through the superconductor per second.
Explanation:
Given :
Current 
A
Charge of electron 
C
Time 
sec
From the formula of current,
Current is the number of charges flowing per unit time.
Where 
number of charges means in our case number of electrons
Therefore, electrons are moving through the superconductor per second.
