Answer:
These are called kinematics equations.
Explanation:
These equations are used when there is either a constant velocity motion or a constant acceleration motion.
It doesn't. We do.
We rotate in such a way that the sun looks like it is rising and falling, but it really isn't.
The heaviest ball will have the most Potential Energy loss and Kinetic Energy gain, so your answer should be D
Answer: liquid
explanation: 1 liter is a measurement of liquids, not solids, or gases.
Liquids also have a set volume, but can flow to take the shape of the bottom of their container.
An experimental variable is a variable that is being tested to answer a scientific question; while a control variable is a variable that is not being altered or changed during the experiement to serve as a constant. An example of an experimental variable is plant food solution A and whether it makes a kidney bean sprout faster than plant food solution B. An example of a control variable is water, because there is no plant food mixed in to create a solution; so it will serve as a natural constant.
