The acceleration is defined by force divided by the mass of the object. So, When the smaller object is hit by a small force, it can produce equal acceleration which is same as that of the bigger body hit with large force.
<h3><u>Explanation:</u></h3>
Force is defined as the product of the mass of the body its applied to and the acceleration of the body in the direction of the force. So acceleration is force divided by the mass of the body.
Let the mass of the smaller body be m and that of the larger body be M.
The smaller force applied on the smaller body be f and the larger force applied on the larger body be F.
So acceleration of the larger body = F/M.
Acceleration of the smaller body = f/m.
For the accelerations to be same,
F/M = f/m.
Or F/f = M/m.
So when the ratio of the force applied on two bodies is in ratio of their masses, the acceleration becomes equal.
Electric current is when electrons start to flow around a circuit. We use an ammeter to measure it and it is measured in amps
Potential difference (also called voltage) is how big the push on the electrons is. We use a voltmeter to measure it and it is measured in volts.
Resistance is anything that resists an electric current. It is measured in ohms”.
(Words: volts, amps, ohms, voltage, ammeter, voltmeter).
Answer: 
is the reducing agent
Explanation:
Oxidation reaction : When there is an increase in oxidation state number.
Reduction reaction : when there is a decrease in oxidation state number.
Fe has undergone oxidation, as its oxidation state is changing from+2 to +3.
Mn has undergone reduction, as its oxidation state is changing from +7 to +2.
The chemical agent which itself get oxidized and reduce others is called reducing agent. is a reducing agent.
The chemical agent which itself get reduced and oxidize others is called oxidizing agent. 
is an oxidizing agent.
.
answer is B
because both sides have equal numbers of atomos
