Newton's second law of motion gives the relationship between the force and acceleration.
The second law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force

Evaporation: The phenomenon of change of a liquid into vapours at any temperature below its boiling point is called evaporation. For example spreaded water on the floor disappears after some time even when the temperature of the surface of the floor is much lower than the boiling point of water.

Modes of transmission of disease
- The diseases that spreads from an infected person to a healthy and disease free person are called communicable diseases.
- These diseases spreads when an infected person sneezes or coughs, they throw tiny droplets of water into the air that contains the microbes of the infection.
- A healthy person standing nearby when inhale the air they take in the infected air and may fall sick.
- Some example of communicable diseases are chicken pox, tuberculosis, Pneumonia, etc.
- These diseases also spreads when the excreta of an infected person somehow gets mixed with drinking water used by other people to drink.
- Diseases like cholera, typhoid spreads through this means and cause disease to a new host.
- Communicable diseases also spread through sexual intercourse between an infected person and a healthy person.
- Therefore, diseases like Acquired Immune Deficiency Syndrome (HIV/AIDS), syphilis are sexually transmitted diseases (STDs).

| Atomic Mass | Atomic Number |
| Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. | Atomic number is usually the number of protons present in an element’s nucleus. |
| It is the average weight of an element. | It is the total number of nucleons in the atom’s nucleus. |
| Atomic mass is denoted by A | The letter Z is used to represent an atomic number. |
| Atomic mass cannot be be used to define the type of element. | Atomic number mainly helps in the classification and identification of an element. |
| Atomic mass is also used to classify different isotopes of the same element | Isotopes only share the same atomic number. |
| Atomic mass is mostly measured using atomic mass unit (amu). | Atomic number is just a digit that is used to place elements in a periodic table. |

mass = 50kg
time taken = 30 sec
steps =30
each height =20cm =0.2m
so, the total height = 6m
now, power =work / time ...(1)
work = force * distance ...(2)
and force = weight = mg = 50kg * 10m/s² = 500 N ...(3)
now, putting the value of (2) and (3) in (1)
power = 500 * 6 / 30
power = 3000 / 30
∴power = 100 W

given height,s=500m
g=10
speed of sound =340
on analysing we get that we have to find time period
first analyze the data and apply different formulas for it then see which formula suits the best.
the formula that should be used here is
s=ut+1/2at2
u=0,
500=0+1/2x10xtxt
we get t=10 sec
now the time for the resound=500/340=1.47 sec
total time=10+1.47=11.47 sec

A push or pull on a body is called force.
Newton has given three laws to describe the motion of the bodies. These are known as Newton’s laws of motion.
Newton’s first law of motion states that a body at rest will remain at rest, and a body in motion will continue in motion in a straight line with a uniform speed, unless it is compelled by an external force to change its state of rest or of uniform motion.
The second law of motion states that the rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force.
The third law of motion states that when one object exerts a force on another object, the second object instantaneously exerts a force back on the first.
