Answer:
1. D. They can be a substance, material, object or source of energy.
2. B. The properties will be different.
3. C. When two reactants form one product, the reaction is spontaneous.
The formula to get the velocity is V=D/T. First you need to determine the distance and time at a certain point and plug it into the equation and that will be your velocity at that point. To get it between two points you complete the directions two times and find the average or use the slope formula, slope = rise/run; slope = (y2 - y1) / (x2 - x1).
Answer:
B. get smaller
Explanation:
The parallax angle of a star measured with respect to the Earth is inversely proportional to the distance of the star from the Earth:

where
is the parallax angle, measured in arcsec
d is the distance between the star and the Earth, measured in parsec
Therefore, if the star Alpha Centauri is moved farther from Earth, then d increases, and therefore the parallax angle will get smaller.
