Let uniform acceleration be a

Acceleration is defined as rate of change of velocity

  ......................(1)
where v is velocity of an object at time t

By integrating above ewqn.(1) , we get

where u is velocity at time t = 0 and v is velocity after time t seconds

from above integration we get ,  v - u = a t   or  v = u + ( a t )  ...................... (2)

velocity is defined as rate of change of displacement 

 ...................(3)

Where S is distance travelled.

By integrating above equation (2) , we get

Where x_o is initial position and x is position after time t

x - x_o = u t + (1/2) a t² .................. (4)

If the object travelled a distance S staring from initial velocity u and attained final velocity v after travelling distance S in time t , then we have

S = (1/2) ( u+v ) t  ...............(5)

Let us substitute t from eqn.(2) in eqn.(5) as  t = [ ( v - u ) / a ] , then we have

S = (1/2) ( u + v ) [ ( v - u ) /a ]    or  v² = u² + ( 2 a S )  ..................  (6)

Eqn.(2) , eqn.(4) and eqn.(6) are equations of motion

Structural composition means the number of people engaged in different sectors.

During pre independence india the structural composition was:

• Primary sector  - Accounted for 70-75% of population
• Secondary sector - Accounted for only 10% of population
• Tertiary sector - Accounted for 15-20% of population

Ideal solution is that solution which follows Raoult's law. An ideal solution or ideal mixture is a solution in which the enthalpy of solution ( ΔHsolution​,ΔVsolution​,ΔSsolution​ is 0 ,with the closer to zero the enthalpy of solution, the more "ideal" the behavior of the solution becomes

When the ball is thrown vertically upward its velocity decreases as it moves upward due to the gravitational force acting on it downwards and thus the graph slopes downwards with a negative gradient.

When it reaches a certain height, that is at a stationary point, the velocity becomes zero and at this point the graph cuts the x axis.

The ball then comes back with an increasing velocity from zero to its initial position and at this point the graph slopes downwards from the x axis.

Mr. Frank is a vibrant young science teacher and the students at the college like him well, but he is afraid his relationship with them is too informal and friendly, undermining his attempts as an educator.

He is a science teacher at the college where he studies Taplow. He is an inexperienced teacher whose opinions on education are lenient and contemporary. He's quite frank and seems to have a relationship with Mrs. Crocker Harris.

Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T. The law is named after Max Planck, who proposed it in 1900. It is a pioneering result of modern physics and quantum theory.

The three types of earthquake waves are described below:

• ‘P’ or longitudinal waves or primary waves -  These waves travel in the direction of their movement. They can travel through solid as well as liquid matter.
• ‘S’ or transverse or secondary waves -These waves travel at right angle to the direction of their oscillation. They can travel in solid media only.
• ‘L’ or Long Waves -  These are surface waves. These do not go deep into the earth.

"Word size" refers to the number of bits processed by a computer's CPU in one go (these days, typically 32 bits or 64 bits). Data bus size, instruction size, address size are usually multiples of the word size. ... In computing, a word is the natural unit of data used by a particular processor design.

Ordinal measurement of utility refers to the measurement (or expression) of utility in terms ranks like high or low (more or less). Ordinality means that utility can be ranked based on consumer preferences.

Ordinal utility theory states that utility cannot be measured, it can only be ranked or ordered according to the preference of the consumer. Ordinality means that utility can be ranked.

Growth

1. Growth is quantitative.
2. Increase in a country's real level of national output which can be caused by an increase in the quality of resources.
3. Economic Growth can be measured by an increase in a country's gross domestic product.

Development

1. Development is quantitative and qualitative
2. Increase in living standards
3. Leads to the creation of more opportunities in the sectors of education, healthcare, employment

1. Recognise the functional group in the compound. This will determine the suffix of the name 

   Functional group	suffix
   alkane	-ane
   alkene	-ene
   alkyne	-yne
   alcohol	-ol
   aldehyde	-al
   ketone	-one
   carboxylic acid	-oic acid
   ester	-oate

    The suffix associated with various functional groups.

2. Find the longest continuous carbon chain that contains the functional group (it won't always be a straight chain) and count the number of carbon atoms in this chain. This number will determine the prefix (the beginning) of the compound's name .

   Carbon atoms	prefix
   1	meth-
   2	eth-
   3	prop-
   4	but-
   5	pent-
   6	hex-
   7	hept-
   8	oct-
   9	non-
   10	dec-

     The prefix of a compound's name is determined by the number of carbon atoms in the longest chain that contains the functional group.

3. Number the carbons in the longest carbon chain (Important: If the molecule is not an alkane (i.e. has a functional group) you need to start numbering so that the functional group is on the carbon with the lowest possible number). Start with the carbon at the end closest to the functional group.

4.  

   Look for any branched groups:

   • Name them by counting the number of carbon atoms in the branched group and referring totable he group on the main carbon chain. If there is more than one of the same type of branched group then both numbers must be listed (e.g. 2,4 -) and one of the prefixes listed in must be used. Important: If the molecule is an alkane the branched group must be on the carbon with the lowest possible number.
   • The branched groups must be listed before the name of the main chain in alphabetical order (ignoring di/tri/tetra).

   If there are no branched groups this step can be ignored.

   Number	prefix
   2	di-
   3	tri-
   4	tetra-

   Table 4.7: Prefixes for multiple substituents with the same name. These apply to multiple functional groups as well.

5. For the alkyl halides the halogen atom is treated in much the same way as branched groups:

   • To name them take the name of the halogen atom (e.g. iodine) and replace the -ine with -o (e.g. iodo).

     Halogen	name
     fluorine	fluoro
     chlorine	chloro
     bromine	bromo
     iodine	iodo

     Table 4.8: Naming halogen atoms in organic molecules.

   • Give the halogen atom a number to show its position on the carbon chain. If there is more than one halogen atom the numbers should be listed and a prefix should be used (e.g. 3,4-diiodo- or 1,2,2-trichloro-). See <a href="https://intl.siyavula.com/read/science/grade-12/organic-molecules/04-organic-molecules-03#tab:organic:prefix2">Table 4.7</a> for a list of the prefixes.
   • The halogen atoms must be listed before the name of the main chain in alphabetical order (ignore di/tri/tetra).

   If there are no halogen atoms this step can be ignored.

6. Combine the elements of the name into a single word in the following order:

   • branched groups/halogen atoms in alphabetical order (ignoring prefixes)
   • prefix of main chain
   • name ending according to the functional group and its position on the longest carbon chain.

Development is the pattern of progressive, orderly, and predictable changes that begin at conception and continue throughout life. Development mostly involves changes — both growth and decline, as observed during old age.
