Answer:
30kg m/s.
Explanation:
30 kg m/s
Explanation
Momentum = Mass × Velocity = 10 kg × 3 m/s = 30 kg m/s
Its momentum is 30 kg m/s.
Explanation:
Momentum is defined by the following equation:
p=mv
where m is the mass of the object in kilograms, v is the velocity of the object in meters per second
p=10 kg⋅3 m/s
=30 kg m/s

Answer: option (4) The reacting particles have more energy and
collide more frequently.
Explanation:
1) In order to a a reaction happen, the reactants must reach the activation energy, which is the energy needed to form the activated complex
2) Then, the higher the energy of the reactants, the less the gap between the energy of the reactants and the activation energy.
3) As per the collision theory, the reactant molecules must collide with energy at least enough as to reach the the activation energy.
4) The kinetic energy of the molecules is higher as higher is the temperature.
Then, you conclude that when you increase the temperature, the molecules will have more energy, will move faster, will collide with more energy, and will produce more effective collisions, which increases the rate of reaction.
If you put something in water its not wet until you pull it out of the water.
