What does the cultural heritage of India comprise of?​

Answer:

1. 13yrs

2. 14yrs

3. 15.5yrs

4. 12.5yrs

The new average age of the group is 12.5 Years if The average age of a group of 8 persons was 14 years A person with age 28 years left the group and a new person with age 16 years joined the group

• The average age of a group of 8 persons was 14 years
• A person with age 28 years left the group
• A new person with age 16 years joined the group

• The new average age of the group

• [tex]\text{Mean}=\dfrac{\text{sum of all the obervations}}{\text{number of the observations}}[/tex]

Find Total age of the group

Number of Persons x Average Age

8 x 14 = 112  years

One person left and one person joined hence total persons are same as earlier 8

Find New Total age

112 - 28  + 16

= 100 Years

Find New Average age

100/8

= 12.5 Years

Hence , The new average age of the group is 12.5 Years

Answer:

By 1920, physicists knew that most of the mass of the atom was located in a nucleus at its center, and that this central core contained protons. In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron

Explanation:

How did Chadwick prove the existence of neutrons?

To prove that the particle was indeed the neutron, Chadwick measured its mass. He could not weigh it directly. Instead he measured everything else in the collision and used that information to calculate the mass. For his mass measurement, Chadwick bombarded boron with alpha particles.

What actually is the question?

Answer:

Respected Principal, teachers and my dear friends.

Today, we have gathered to observe 'Earth Day'. We are aware that the environment is deteriorating year by year. Earth Day is celebrated to demonstrate support for environmental protection. Of late, climatic changes have been observed majorly due to the fast depletion of resources because of urbanisation and commercialisation. These climatic changes have to lead to more intense heat waves, rise in sea level and are a major threat to the bio-diversity. In India especially, climate change has disturbed the crop cycle due to rain deficit monsoons. But we have not lost our planet Earth completely. We may feel,

"How can one person bring about any change?" However, we need to realise that every person's actions matter. By making small changes in our daily lives like switching off the t.v., a.c when not in use, we can bring about big changes. Afforestation is a great solution to the problem as trees are the sources of sustaining life on earth. So, let's take an oath to do our best for the environment and our planet.

Thank you.
