Answer:
Height and mass
Explanation:
The potential energy of a body is the energy due to the position of a body.
It is mathematically expressed as:
Potential energy = m g h
m is the mass of the body
g is the acceleration due to gravity
h is the height of the body
Acceleration due to gravity on the earth surface is a constant.
As mass and height of a body increases, the acceleration due to gravity will also increase.
Answer is: B. designing an experiment to test the plum pudding model.
Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate, but before testing, he thought that plum pudding model is correct.
Rutherford theorized that atoms have their charge concentrated in a very small nucleus.
This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).
Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.
That is different from Plum Pudding model, because it shows that most of the atom is empty space.
Answer:
A river and its tributaries make up a watershed (aka river system or drainage basin)
Pls mark me as brainliest
Answer:
<h2>Chemical equilibrium, however, is always the point at which there is no bias towards creating products or reactants. If the forward reaction rate and reverse reaction rate are equal, then there is no net change in concentration of the reactants or products. This makes them appear to be stable.</h2>
