The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. UNIT: 2 Force
• Force is an external agent , which changes or tends to change the
state ,shape ,acceleration or direction of motion of an object.
• SI unit of force is Newton (N) while its CGS unit is dyne
(1N=105dyne )
• 1 Newton Force: The force required to produce the acceleration
of 1 m/s2 on a body of 1 kg mass is called one Newton force.
i.e 1N= 1 Kg x 1mls2

3. Force
Scalar Quantities: The physical quantities, which have a
magnitude but no direction are called scalar quantity.
Mass , length, time, density, speed, work, work etc. are a few
examples of scalars.
• Vector Quantities: The physical quantities, which have both
magnitude as well as direction are called vectors quantities.
Velocity, displacement, acceleration, force, momentum etc.
are examples of vector quantities.

4. Uniform Velocity & Non-uniform Velocity
• A body is said to have uniform velocity if it covers equal distance
in equal intervals of time in a particular direction.
• A body is said to have non-uniform velocity (i.e. variable velocity)
if it covers unequal distance in equal interval of time in a
particular direction.
• Acceleration: The rate of change of velocity with respect to time is
called acceleration.
Its SI unit is m/s2 & it is a vector quantity. Its value may be
positive or negative. 8/18/2020www.yepnepal.com

5. Retardation & Equations of motion
• Acceleration = Change in velocity / time taken
Acceleration = Final velocity – Initial velocity / time taken
a= v-u / t
• Retardation: The negative acceleration is called retardation. It has the same
unit like acceleration.
• Equations of motion:
1. v= u + at ………. (i)
2. s = u + v/2 x t …..(ii)

Case 1: For a freely falling body under gravity from a certain height
(h), in such case: a = g & s = h.
Case 2: When a body is thrown vertically upwards, in such case: a =
-g & s=h.
Case 3: When body is just released from rest, u=0 , a= g & s=h.
16. Exercise based on Rest,Motion,Scalar & Vector
quantities
1. What is the acceleration of body moving with a uniform
velocity? Why?
2. The velocity of an accelerated body may be zero. Explain with
reason.
3. Total displacement can be zero but not the total distance of a
moving body, why?
4. A train is travelling with a velocity of 72 km/hr and after 10
seconds its velocity changes to 120 km/hr. What is its
acceleration? (Ans: 1.33 m/s2 )

2. A moving truck takes a much longer time to stop than that taken
by a car when brakes are applied to both of them at once, why?
3. An athlete runs some distance before taking a long jump, why?
4. A moving ball on the play ground is stopped even if no player
touch it. Does it against the Newton’s first law of motion? Why?
5. A cricket ball causes severe hurt than a shuttlecock when one is
hit by them. Why?

1.When a moving bus suddenly stops, the passengers fall forward,
why?
2. It is difficult to catch a cricket ball as compared to a tennis ball
