1.1 If the Sun should suddenly explode (it can’t) how long would it take for us to notice the event? * According to scientists we have at least 5-6 million years before the sun would ever die out or explode. However if a phenominon like that were to occur there are diffent theories to what might happen. It would take light from the explosion eight minutes to travel the 93 million miles from the sun to the earth. However‚ Newton’s Law of Gravity claims that Earth would suffer an immediate departature

ES 1010‚ Unit 8 Question 11 - Discuss stellar evolution (describing each stage in brief). What forces are opposing one another throughout the life of a star and how do they influence the various stages in the life cycle of a star Stellar evolution stars exist because of gravity. The two opposing forces in a star are gravity (contracts) and thermal nuclear energy (expands). Stage 1 Birth is where gravity contracts the cloud and the temperature rises‚ becoming a protostar. Protostars are a

You Can prove that radius to the point of contact of a tangent is perpendicular by Take two Iron Rings with a radius of a pin that you have like a stitching needle.. The iron rings should be at a thickness of 1 cm... Join the two rings by superimposing but not exactly‚ without gap. just leave a gap between the two circumference of the circle such that there is parallel gap throughout the two rings then join them at two points{one at any where and another at straight opp to the other} using m~seal

by Fredrick William Herschel on August 28‚ 1789‚ during the first use of his new 1.2 m telescope‚ then the largest in the world.[22][23] Herschel first observed Enceladus in 1787‚ but in his smaller‚ 16.5 cm telescope‚ the moon was not recognized.[24] Its faint apparent magnitude (+11.7m) and its proximity to much brighter Saturn and its rings make Enceladus difficult to observe from Earth‚ requiring a telescope with a mirror of 15–30 cm in diameter‚ depending on atmospherical conditions and light

Comets Belinda Scott Introduction to Physical Science – SCI 110 Dr. Paul A. Belony‚ Jr. | | A comet is a small body‚ roughly the size of a small town‚ in the Solar System. It is made up of ice‚ rock‚ dust‚ carbon dioxide‚ ammonia‚ methane and more. Some researchers think comets might have originally brought some of the water and organic molecules to Earth that now make up life here. Comets become visible as they near the Sun. The tail of a comet is its most

Chapter 1 Introduction 1.1 History of Free Space Optics Even though fibre-optic communications gained worldwide acceptance in the telecommunication industry‚ FSO communications is still considered relatively new. But optical communication‚ in various forms‚ has been used for thousands of years. The Ancient Greeks polished their shields to send signals during battle. In the modern era‚ semaphores and wireless solar telegraphs called heliographs were developed‚ using coded signals to communicate

Some ten kilometers from the heart of Chiang Mai city stands the province’s iconic national park -- Thailand’s tallest mountain: Doi Inthanon. In native northern languages‚ Doi simply means a mountain or its peak. Surrounding this immense‚ gigantic granite is a 1000 square-kilometer national park area stippled with waterfalls and trek trails‚ all enveloped by an impermeable curtain of wilderness.

CHAPTER 7 SPEED - Is a scalar -measures “how fast an object is moving” INSTANTANEOUS SPEED -the speed at any given instant in time AVERAGE SPEED -the average of all instantaneous speed; found simply by a distance or time ratio. SPEED= distance/Time TIME= Distance/Time DISTAnce= Speed*Time VELOCITY- is a vector Refers to the rate at which an object changes its position VELOCITY= displacement/time MOTION- is a change in position with respect to a reference ENERGY-
