Initial Speed (u)= 54 km /hr = 54 *1000 m / 3600 s = 54*5/18 = 15 m/s
( 1km = 1000 m and 1hr = 60 mins = 60*60 seconds = 3600 seconds)
Time = 8 seconds
Final Velocity (V) = 0
we know that ,
v = u + at
0 = 15 + a*8
0 = 15 + 8a
a= -15/8 m/s²
Therefore , acceleration is -15/8 m/s²

The Full form of DNA is Deoxyribonucleic acid. Deoxy means lack of an oxygen atom, Ribo means ribose sugar, Nucleic is found in the nucleus of cell and Acid contains negatively charged phosphate ion which is acidic. Deoxyribonucleic acids are hereditary material for human and most other living beings, I.e., they carry the genetic information for growth, development, functioning and reproduction of all known living organisms.

Temperature in Kelvin = Temperature in °C + 273
Substitute the given value in the equation and then calculate the other unknown value.
a. 293 K = (293 – 273)
= 20 °C
b. 470 K = (470 – 273)
= 197 °C

Fractional Distillation:
Principle: This method is used for the separation of a mixture containing two miscible liquids, for which the difference in their boiling points is less than 25o C.
Technique: The mixture is kept in a distillation flask attached with a fractionating column, having glass beads. The flask is then carefully heated. The mixture first evaporates and later condenses. The glass beads present in the fractional column provide a larger surface area for the vapours to cool down. This technique is used to separate mixtures made up of two miscible liquids with a difference in their boiling points less than 25oC.

o concert Kelvin scale into Celsius scale we have to subtract 273 so
293K = 293 - 273 = 20 ºC,

Because of great force of attraction particles of solids are closely packed together. This makes the space between particles of solids almost negligible. The lowest kinetic energy of particles does not able to move the particles of solids.

Yes, it can be classified as a solid. It is an elastic solid which changes its shape on stretching and regains the same when the stretching force is removed.

| Sl. No. | Differentiating Property | Distance | Displacement |
| 1 | Definition | The complete length of the path between any two points is called distance. | Displacement is the direct length between any two points when measured along the minimum path between them. |
| 2 | Denotation | d | s |
| 3 | Direction Consideration | To calculate distance, direction is not considered. | To calculate displacement, direction is taken into consideration. |
| 4 | Quantity | Distance is a scalar quantity as it only depends upon the magnitude and not the direction. | Displacement is a vector quantity as it depends upon both magnitude and direction. |
| 5 | Route Information | Distance gives the detailed route information that is followed while traveling from one point to another. | As displacement refers to the shortest path, it does not give complete information of the route. |
| 6 | Formula | Speed × Time | Velocity × Time |

MKS is the system of units based on measuring lengths in meters, mass in kilograms, and time in seconds. MKS is generally used in engineering and beginning physics, where the so-called cgs system (based on the centimeter, gram, and second) is commonly used in theoretic physics. MKS and CGS system of measurement are widely used and are considered easier too because most of the object that we use in our daily life are smaller in size which is easily measured MKS and CGS system. Physical quantity: Those quantities which can be measured are known as physical quantity.

Plants and animals are put into different categories on the basis of Mode of nutrition. Plants are autotrophs, while animals are heterotrophs. Cell wall is present in plant cells, while it is absent in animal cells. Also, locomotion, absence of chloroplasts etc. make them different. Plants do not need to move from one place to another, while most of the animals need to move in search of food.

1. Solids have a definite shape and a definite volume because the particles are locked into place.
2. Solids do not flow easily because the particles cannot move/slide past one another.
3. Solids are not easily compressiblebecause there is little free space between particles .

At room temperature (25°C), water is a liquid because it has the following characteristics of liquid:
- At room temperature, water has no shape but has a fixed volume i.e., it occupies the shape of the container in which it is kept.
- At room temperature, water flows easily.

Pressure has no effect on solid and liquid whereas the volume of gas decrease with increase in pressure. This leads to the conversion of the gaseous state into a liquid state and eventually into a solid state.
The volume of the gas decreases on applying pressure on gases because gases are compressible.

To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed. Instantaneous speed is the exact speed that a body is moving at, at a given instant in time. It is a true measure of the body's motion for that point in time. An average speed tells you how much distance a body covers during a certain time span, but it does not tell you much about the actual motion that occurred.
