Yes, because electric charges have electric field surrounding them that allow them to exert forces on other objects without touching them.
Unlike the one-way flow of energy, matter is recycled within and between ecosystems. Every living organism needs nutrients to build tissues and carry out essential life functions.
A baseball is accelerated downward at 9.8 m/s^2 when the only vertical force acting upon the baseball is gravity.
Electromagnetic force between the molecules!
Answer:
The variable manipulated or controlled by the experimenter is called the independent variable.
Example:
If the flow velocity at the bottom of a tank is measured by varying the height of water in the tank, we are measuring velocity as a function of water height.
Therefore,
water height = independent variable (controlled)
velocity = dependent variable (measured in response to water height).
Mathematically,
v = f(h)
where v = response variable (dependent)
h = controlled variable (independent).
