An object increases its energy when raised through a height. This is because work is done on it against gravity while it is being raised. The energy present in such an object is the gravitational-potential energy. This gravitational-potential energy of an object at a point above the ground is defined as the work done in raising it from the ground to that point against gravity. An object of mass m, when raised through a height h from the ground, then work done by this object will be W = force x displacement = mg x h = mgh

W=F⋅scosθ   Where, W is the work done F is the force applied s is the distance travelled by the body θ is the angle between the direction of force and the direction of motion of the body

The work done on a body is given by:

W=F⋅scosθ
 

Where,
W is the work done
F is the force applied
s is the distance travelled by the body
θ is the angle between the direction of force and the direction of motion of the body

The work done on a body is given by:

W=F⋅scosθ
Where,
W is the work done
F is the force applied
s is the distance travelled by the body
θ is the angle between the direction of force and the direction of motion of the body

Work done is equal to zero assuming earth revolves around the sun in a perfect circle. As Work=Force∗Displacement∗cosθ Where θ is the angle between force and displacement . In this case θ=90degree As centripetal force is involved where earth is pulled towards the sun and direction of motion at each point is tangential to the orbit and as tangent makes 90degree with radius θ=90degree Cos90o=0 Thereby F∗S∗cos90=F∗S∗0=0 HENCE NO WORK IS DONE .

Cos90^o=0

Thereby F∗S∗cos90=F∗S∗0=0

HENCE NO WORK IS DONE .

No, the child is not doing any work because according to physics work is defined as whenever a force produce motion and the object is displaced then it is said to be work done. Bt here child is sitting at one position no force or displacement takes place so here work is not donee.

Ec =power × time

= 40×6/1000

Ec in 30 days = 24×30/100 = 7.2kwh

Speed is measured as the ratio of distance to the time in which the distance was covered.

Speed = Distance /Time

Minimum Support Price policy, provision for crop insurance, subsidy on agricultural inputs and resources such as power and fertilizers, Grameen Banks, Kissan Credit Card and Personal Accident Insurance Scheme are also some of the reforms bought by I

Various initiatives taken by the government to ensure the increase in agricultural production are:

•  Collectivisation, consolidation of holdings, cooperation and abolition of Zamindari etc. were given priority to bring about institutional reforms in the country after independence.
•   Land Reform was the main focus of our ‘First Five Year Plan’.
•  The Green Revolution was based on the use of package technology and the White Revolution were some of the strategies initiated to improve the Indian agriculture.
•  Minimum Support Price policy, provision for crop insurance, subsidy on agricultural inputs and resources such as power and fertilizers, Grameen Banks, Kissan Credit Card and Personal Accident Insurance Scheme are also some of the reforms bought by Indian Government.

Mass = 1.5 kg Height = 8 m g = 10 m/s² Potential energy (just before falling) = mgh = 1.5 × 8 × 10 = 120 joule.

From, Shaan #32Kailash colony New Delhi To, The editor Local newspaper New Delhi Date.......... Subject:Misuse and poor maintance of public park Respected Sir/Madam, As I Shaan staying Kailash colony here by is there to inform you that the public park near Kailash colony is really misused by many people.....there is no any proper care taken in cleaning the park.Even children's are refusing to come this park because the items necessary for children to play is broken and rusted..... I hope that you will publish my observation about the park and bring to the notice of the area councilar..... Thanking you, Yours Faithfully, Shaan.

India has maintained good relations with all the post-communist countries but its relations with Russia are an important aspect of India's foreign policy. The relations during the Cold War were as given below:

1)  Economic : Russia gave aid and technical assistance for steel plants like Bhilai, Bokaro,Visakhapatnam and machinery plants like Bharat Heavy Electricals Ltd. The Soviet Union accepted Indian currency for trade when India was short of foreign exchange.

2) Political: The Soviet Union supported India's stand on Kashmir issue in the UN. It supported India during the war with Pakistan in 1971.

3) Military: India received most of its military hardware from the Soviet Union. The Soviet Union entered into various agreements allowing India to jointly produce military equipment.

4) Culture : Hindi films and Indian culture became popular in the Soviet Union. A large number of Indian writers and artists visited the USSR.

 

The major events in the Indo-China relations are as examined below :

1. Great powers : Before the advent of western imperialism both were great powers. However, there was limited interaction between the two and neither country was very familiar with the other.

2. Hindi-Chini bhai-bhai: After independence for a brief period the two countries came closer and the slogan Hindi-Chini bhai-bhai became popular.

3. Tibet (1950) and border conflict (1962) : Chinese takeover of Tibet (1950) and border conflict (1962) had negative effect on relationship. Diplomatic relations between the two countries were downgraded until 1976.

4. Change in China’s political leadership : After the change in political leadership the policy have become more pragmatic and less ideological. A series of talks to resolve the border issue were initiated in 1981.

5. Rajiv Gandhi’s China visit and its outcomes : Rajiv Gandhi’s visit in December 1988 had improve the relations. Measures to maintain peace have been taken. Various agreements for cooperation have been signed. India-China trade has been growing at 30 percent per year since 1999. It is hoped that more positive and sound relationship will be established in future.

Consequences of emergency were :

• Fundamental Rights were suspended.
• The power of Judiciary were limited.
• Press was censored.
• All the power were concentrated in the hands of Union Government.
• Civil liberties of the citizens were taken away.

Jayaprakash Narayan was born in 1902 CE in Bihar. He completed his higher education in American Universities for more than seven years. While studying in America, he became familiar with Socialist philosophy. On returning to India, he joined Congress as per the guidance of Nehru. He entered politics in 1974 and called for Total Revolution.As a result of this movement, the Janatha Party came to power. He was fondly called as Loknayak by the people.

Integral humanism was a set of concepts drafted by Deendayal Upadhyaya as a political program and adopted in 1965 as the official doctrine of the Jan Sangh.

M. S. Golwalkar believed in the concept of Organicism, from which the Integral Humanism was not very different. In Integral Humanism, Golwalkar's thoughts were supplemented by appropriating major Gandhian principles and presented as version of Hindu Nationalism.

Plzz explain it in simple words...

Your body has two types of skeletal muscle fibers: slow-twitch (type I) and fast-twitch (type II).

Slow-twitch muscles give you the stamina to nail endurance tasks like distance running. People use fast-twitch muscles in explosive actions, like sprinting, jumping, or playing a cameo in a “Fast and Furious” movie. (If you have furious-twitch muscle fibers, seek medical assistance.)

During aerobic exercises like running or swimming, slow-twitch fibers are the first to contract. But when you’re throwing around heavy kettlebells or playing a sport, you’re using fast-twitch muscles.

The title 'A house is not a home' is apt in relation to the story. In the story, the author's house gets completely destroyed in a fire. Due to this, he and his mother had to take refuge at his grandparents' home and later in a rented an apartment. The places where the author lived after the fire incident cannot be called a home. A home is a place where one gets comfort, coziness and the joy of longing. One can find true happiness and comfort within the premises of home. On the other hand, a house is without these sentiments and emotions. House is just a confined place made-up of the four walls. It can never be matched to a home. There were merely places where he took shelter. Home is where one has comfort, security, and freedom of doing whatever one wishes to. Moreover, these places were without the belongings and things which the author loved. As one has a sense of belonging to his home, it cannot be fulfilled by a place where one takes temporary shelter. Hence, the title of the story 'A House is Not a Home' is justified.
