sun sets

Sun sets in the west. - What type of event is this? => Likely or Impossible or Certain or Unlikely..

takes place only in the presence of sunlight. In this reaction, the light energy from the sun is absorbed by the photosynthetic pigments and is used to break down the water molecules. This is called the photolysis ('photo' is light and 'lysis' refers to break down) of water. This rele..

. Hence, energy flows from sun through producers to consumers in a single direction only. The decreasing energy level at each step sets the limit of trophic levels to a maximum of 4 or 5. It is the continual trapping of light energy by green plants that makes good this loss and ..

To Determine the Height of an Accessible Tree using a Sextant - AB and CD are two mirrors fixed, as in the diagram, parallel to each other and facing each other, i.e., the reflection on CD is seen on AB. A small telescope and a vernier travelling over a scale, graduated in degrees, constitute the s..

. This results in the rays bending towards the normal and appears to come from S 1 , the apparent position. Therefore sun appears above the horizon. It is for the same reason it continues to be seen a few minutes after it actually sets. Hence the day becomes longer by about 4 mi..

Summary - The first two parts describe how the old sailor (Ancient Mariner), defying laws of hospitality, cruelly kills a sea bird - an Albatross, and is then haunted and followed by the spirit of Albatross. In the first part of the poem, the sailor appears suddenly as three guests are about to ent..

As light is transverse in character, all directions of vibrations of electric vector in the unpolarised light are confined to the XY plane. While looking along the X axis, vibrations of electric vector parallel to Y axis are seen and similarly along y axis. Hence light scattered in a direction perp..

Introduction - The atmosphere resource of our world is unique and available to our planet only. No other planet is found to have similar atmosphere. Earth's atmosphere is a legacy from history of this planet. It was formed billions of years back. In the formative years, as the earth started cooling..

Let us consider a student seated on a stool that can rotate freely about a vertical axis. The student, who is set into rotation at a modest initial angular speed w i , holds two dumbbells in an outstretched hand. His angular momentum lies along the vertical rotation axis, pointing upwards..

Illustrations of the Law of Conservation of Angular Momentum - Let us consider a student seated on a stool that can rotate freely about a vertical axis. The student, who is set into rotation at a modest initial angular speed w i , holds two dumbbells in an outstretched hand. His angular m..
