Oxidation is the half reaction that can occur at the anode in a voltaic cell.
Explanation:
In electrodes which is metal strip in voltaic cell the reactions occurs. The two electrodes placed one in each half-cell. The reduction reaction occurs at cathode and oxidation occurs at anode.
A half reaction is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction. Half-reactions are often used as a method of balancing redox reactions.
In an oxidation half reaction, an atom loses electron(s). When an element is oxidized it loses a specific number of electrons.

1) A ball is thrown with the speed of 10 m/s from the 1st stair. The height of each stair is 10cm and the width is 15 cm. on which stair the ball will fall
Voltage<span>, </span>also called<span> electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
So ACTUALLY an "electromotive force", but of your answer choices.

Answer:
The kinds of intermolecular forces that are present in each element Kr-Kr.
Explanation:
Since Kr is an inert gas and in atomic form only it is highly stable.
So, Kr gas does not form molecules.
Between the atoms of inert gas, there exist London dispersion forces.
Hence, the intermolecular forces that are present between Kr-Kr atoms is London dispersion forces.
Answer:
The acceleration of the ball when it begins to move is 200 m/s²
Explanation:
The given parameters are;
The mass of the metal ball, m = 0.025 kg
The force exerted by the magnet on the ball, F = 5 N
From Newton's second law, F = m × a
Where;
a = The acceleration of the ball
Therefore, by substitution, we have;
5 = 0.025 × a
a = 5/0.025 = 200 m/s²
The acceleration of the ball when it begins to move = 200 m/s²
