Why is there a circle around the moon

The moon is currently a perfect circle.

In an unusual event, the moon was perfectly circular in mid-2021. This was a rare occurrence, as the moon’s orbit is elliptical and it’s only ever seen as a full circle when it’s at its closest point to Earth. The moon appeared circular on May 21st, 2021. It wasn’t visible in most of North America due to clouds and rain, but could be seen clearly in South America and parts of Europe.

The moon has been perfectly circular since May 21st, 2021. This is an unusual occurrence as the moon’s orbit is elliptical and it’s only ever seen as a full circle when it’s at its closest point to Earth. The last time this happened was in March 2019, although this time around the full circle was visible from North America too.

Why we celebrate Lohri

Lohri is a harvest festival celebrated by Punjabis and Sikhs in India and abroad.

What is Lohri?

Lohri is a harvest festival celebrated by Punjabis and Sikhs in India and abroad. It’s also known as Lohri, Lao Hari, or Losar. The date of the festival varies according to the lunar calendar, so it falls on different days each year. The most common date for Lohri celebrations is January 13th.

What does Lohri mean?

The word “Loh” means snow, while “Ri” means warmth. This refers to the fact that snow melts during this time of year, making way for warmer weather.

How do you celebrate Lohri?

“Punjabi folk dance”

Lohri celebrations are held in Punjab (the state in northern India where most Punjabis live) and involve firework displays and bonfires. People gather around the fire to sing songs about harvest festivals from their childhoods or Punjabi folk songs about winter. They also eat traditional foods such as sarson ka saag (a dish made with mustard leaves), rotis (bread), makki di roti (flatbread made from corn flour), sevian (small yellow dumplings), gatte ki sabzi (mashed potato curry), kheer (rice pudding) and pakoras (vegetable fritters). During this time, people also take part in kite flying competitions.

Why 15 January is celebrated as Army Day

Army Day is celebrated on January 15 every year in India.

Army Day is celebrated on January 15 every year in India. It marks the raising of the Indian Army as an independent fighting force. The Indian Army was raised on this day in 1887, when Lord Kitchener was appointed Commander-in-Chief of the British Indian Army by Queen Victoria. The army has grown from a force of 50,000 men to one of over 1.4 million active personnel and more than one million reserve personnel today.

The first Army Day was celebrated in 1947 after India gained independence from Britain. Since then, it has been observed annually with parades and other events to mark the achievements of the army and to honour its soldiers who have been killed or wounded while serving their country.

With increase in atomic number the ionic radii of actinides

The ionic radius of an atom is the distance from the center of an atom to its valence electrons.

With increase in atomic number the ionic radii of actinides decreases. This is because as we move from left to right in a period, atomic number increases and hence the number of protons in nucleus also increases. As a result, repulsion between protons becomes more significant than that between neutrons and electrons. Thus, in heavier elements (with higher atomic numbers) there are more protons than electrons and thus larger repulsion between protons leads to smaller ionic radius.
