E. Find some other discoveries Newton has made.

Here are some other discoveries that Newton made:

The laws of motion: Newton’s three laws of motion are the foundation of classical mechanics. They describe the relationship between force, mass, and acceleration.

The theory of gravitation: Newton’s theory of gravitation describes the force that attracts all objects in the universe to each other. Calculus is a powerful mathematical tool that is used in many different fields, including physics, engineering, and economics.

The composition of white light: Newton discovered that white light is actually a mixture of all the colours of the rainbow.

The reflecting telescope: Newton invented the reflecting telescope, which uses curved mirrors to collect light. Reflecting telescopes are more powerful than refracting telescopes, which use lenses to collect light.

Writing I

Study the information below about Pasang Lhamu Sherpa; the first Nepali woman to scale Mt. Everest. Write a short biography of her based on the given information.

Pasang Lhamu Sherpa

Born on December 16, 1961, in Solukhumbu, Nepal, Pasang Lhamu Sherpa hailed from a family deeply rooted in mountaineering. Embracing her passion from a young age, she embarked on her mountain-climbing journey during her teenage years. At the tender age of 17, she ventured to Kathmandu alongside her husband, Lhakpa Sonam Sherpa, and together they established a travel agency.

In 1989, Pasang Lhamu Sherpa embarked on her initial endeavor to conquer Mount Everest, yet despite her utmost efforts, she fell short of reaching the summit. Nonetheless, she triumphed over Mount Pisang (6091m) and Mount Blanc (4848m). Continuing her quest, she made two more attempts on Mount Everest in 1991, scaling heights of 8750m and 8500m on separate occasions.

Finally, on April 22, 1993, Pasang Lhamu Sherpa accomplished her lifelong dream by triumphantly reaching the summit of Mount Everest, etching her name as the first Nepali woman to achieve this feat. Tragically, she succumbed to harsh weather conditions during her descent, at the young age of 31.

Pasang Lhamu Sherpa stands as a revered national hero in Nepal, serving as a beacon of inspiration for women across the globe. In her memory, a highway and a mountain have been dedicated in her honor, while the documentary film “Pasang Lhamu: The First Sherpa Woman on Everest” immortalizes her remarkable story.
