Biology is the study of life
The characteristics of a chemical reaction are:
The lower energy of reactants → Transition state → High energy of products.
<h3 /><h3>What is a chemical reaction?</h3>
A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products.
The characteristics of a chemical reaction are :
Lower energy of reactants
↓

Allelopathy, the pine needles make the ground more acidic so weeds cannot grow and steal nutrients the tree needs
the number is the mass number
the mass number is the number of nucleons (total number of protons and neautrons in the nucleus) so in hydrogen-3 there are 3 nucleons and as hydrogen has 1 proton, there are 2 neutrons
carbon 12 has 12 nucleons (6 protons and 6 neutrons) and carbn 13 has 13 nucleons (6 protons and 7 neutrons)
Answer: The final velocity of both man and hokey puck will be 0.056 m/s.
Explanation: We are given 2 objects and are undergoing collision. The final velocity of both the objects is same. To calculate the final velocity, we will use the principle of conservation of momentum.
This principle states that when the objects that are colliding makes up a system, then the total momentum will remain constant if no external force is applied on it.
Sum of Initial momentum of two objects = Sum of Final momentum of the two objects
Mathematically,
...(1)
where,
are the mass, initial velocity and final velocity of the first object.
are the mass, initial velocity and final velocity of the second object.
Here, man and hockey puck are moving together after the collision, so their final velocities will be same.
Putting values in equation 1, we get:
The final velocity of man and hockey puck is 0.056 m/s.
