What is the major drawback of an AC amplifier? Its output is not drifting less. The output changes with the time and change in supply voltage. It has poor temperature stability, due to this its operating point shifts. At low frequencies capacitor fail and act like a short circuit. What are the advantages and disadvantages […]

Are there male and female earthworms?
Are there male and female earthworms? Earthworms are hermaphrodites, meaning an individual worm has both male and female reproductive organs. Earthworm mating typically occurs after it has rained and the ground is wet. They emerge from the soil and jut out their anterior end. Do earthworms fertilize their own eggs? Earthworms are hermaphrodites (both female […]
What is kinetic theory of matter for Kids?
What is kinetic theory of matter for Kids? The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, […]
Which two particles are found in the nucleus of an atom?
Which two particles are found in the nucleus of an atom? The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge. Which […]
What is a habitat Class 6?
What is a habitat Class 6? The place where organisms live is called habitat. Habitat means a dwelling place (a home). The habitat provides food, water, air, shelter and other needs to organisms.

How is evolution both a theory and a fact?
How is evolution both a theory and a fact? Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change.” What are […]
What is coordinate system and its type?
What is coordinate system and its type? A coordinate system is a method for identifying the location of a point on the earth. Most coordinate systems use two numbers, a coordinate, to identify the location of a point. Each of these numbers indicates the distance between the point and some fixed reference point, called the […]
