Answer:
The hypothesis is only an assumption that has not yet been proven, when it has been tested, and it cannot be shown that it is false, then it is no longer a simple hypothesis, it is a Theory. Hypothesis is when we raise a supposed result. Theory is the result of an experiment.
Explanation:
Kinetic Energy is the energy by virtue of object's motion. In first two options, no motion has occurred, so there would be no energy, and kinetic energy can also be seen in a swinging both which is in last option in the question.
In short, Your Answer would be Option D) A swing moving back and forth
Hope this helps!
B. Polar Molecule
Explanation - polar means that the electrons are not shared evenly. Water (H2O) has two Hydrogen atoms which are positive because they give their electrons away, and one Oxygen atom which is negative because it received the electrons
Answer:
Maximum angle = 3.43⁰
Explanation:
Say that you are given the following information:
vertical distance between the charge plate = 0.03 m
length of the plate = 0.5 m
velocity of the electrons = 5 × 10⁶ ms⁻¹
the maximum angle is given by the formula:
where d = vertical distance between the charge plate
l = length of the plate
substituting the values l and d gives:
maximum angle, 
= 3.43⁰
..because the energy put in to making bonds is greater than the energy given back from breaking bonds.
The exothermic part of the reaction is greater than the endothermic part.
