weighted projective space

It is a thick muscular, reddish brown, conical organ present in the mediastinal space of thoracic cavity between 2 pleura enclosing the lungs. Its broader side is called base and it is forward and upward while the pointed side called apex is backward and downward. It is 9 cm broad and 12 ..

All bodies when projected vertically upwards fall back to earth due to the earth's gravitational pull. The maximum height attained by a body depends upon the initial velocity of the body. This does not mean that no object can escape earth's gravitational pull. We know that the spacecrafts..

Mass is defined as the amount of matter contained in it. SI unit of mass is Kilogram. Mass remains constant throughout the universe. Mass of an object can never be equal to zero. Mass is a scalar quantity. Weight is the force with which an object is pulled towards the cen..

We often hear that an astronaut experiences weightlessness in space. What does this mean? Let us perform a simple experiment to demonstrate weightlessness. Suspend a stone from a spring balance, the pointer of the spring balance shows the weight of the stone. Allow the spring ba..

Special Type of Germination: Vivipary - This is a special type of germination found in mangrove plants. Mangrove plants are found in marshy areas and on the sea coast. In viviparous germination, the seeds germinate while still attached to the parent plant. The embryo grows out of the seed and then ..

Summary - Matter is anything that occupies space. An Atom is the smallest particle of an element that takes part in a chemical reaction. A molecule is the smallest particle of a substance that has independent existence. Atomic mass unit is one-twelfth mass of an atom of carbon (C-12). It is eq..

The units of nervous system are specialized cells called the neurons . The general structure of a neuron is as follows: Around the cell body are short sensory projections called the dendrons. The fine branches of dendrons are called the dendrites. These short fibres receive messages and p..
